Caution: Indicates a potentially hazardous situation which, if not avoided, could result in serious injuries, equipment damages, or interruption of part services.

Note: Indicates a potentially hazardous situation which, if not avoided, could result in injuries, equipment damages, or interruption of part services.

Beryllia Warning: The equipment inevitably adopts components that contain toxic beryllia.

Some components use beryllia as an insulator. It is innocuous to human health when encapsulated in a component. However, when there is damage to the component, it will release the powdery beryllia, and may cause harm to people. The person who contacts or handles this kind of component must know its characteristics and take corresponding measures.

One must not dispose of components containing beryllia randomly, and must get chemical treatment or special waste treatment according to the local codes and regulations.

Electrical Safety High Voltage

Danger: High voltage is dagerous. Direct or indirect contact with high voltage or main supply through a wet object could result in death.

Some equipment of ZTE operates at 220 VAC or 380 VAC, which makes the equipment potentially dangerous. Nobody has the permission to enter a high-voltage area unless properly follow safety rules.

Do follow the local safety regulations when installing any AC power equipment.



Anyone that installs AC equipment must be qualified for high-voltage and AC operations.

Power cables

Note: Never install or disconnect any power cable with power on.

Do shut off power supply before connecting or disconnecting a power cable.

Before connecting a cable, make sure the cable and its label meet the actual installation requirements.

Tools

Warning: Use special rather than common tools for high-voltage and AC operations.

Drilling Holes

Warning: Do not drill the cabinet without permission. Unqualified drilling could damage the wiring and cables inside the cabinet. Additionally, metal pieces inside the cabinet created by the drilling could result a short circuit on the board.

Thunderstorm

Danger: Avoid operations with high-voltage, AC, iron tower, or mast in a thunderstorm.

The lightning storm would give rise to a strong electromagnetic field in the atmosphere. Therefore, one must ground and protect the equipment against lightning strikes.

Static Electricity Note: The static electricity produced by the human body could damage the static-sensitive components, such as large-scale integrated circuits (LC) on the circuit board.

Accumulated electrostatic charges (ESC) derive from friction created by human body movements. Human body can carry a maximum of 30 kV static voltages in dry environment, which could remain on the human body for a long time. An operator carrying static electricity will discharge



electricity through the component and may damage the component when touching a component.

Wear an antistatic wrist strap and ground the other end before touching any equipment or holding a plug-board, circuit board, IC chip, and others, to prevent human static electricity from damaging sensitive components.

Battery Danger: Make sure to have reading safety precautions on handling the battery and known procdures to connect the battery before operating on it.

Inappropriate operations on the battery may result in danger. Prevent the battery from short circuit, electrolyte overflow, or escape. Electrolyte overflow will pose potential threat to the equipment and erode the metal and circuit boards, to damage the equipment and cause short circuits on the circuit board.

Warning: Do not replace the battery of a specified model with other models of battery. Otherwise, it may cause an explosion.

Electromagnetic Radiation The antenna of a running device generates electromagnetic radiation. The safety requirement may not suffice at a place too near the antenna. Only professionals with proper training and relevant qualifications should install and maintain the equipment.

In designing and manufacturing the equipment, the consideration is to achieve trade-off and to minimize the possibility of exposing the electromagnetic radiation to human body. The radiation design of the equipment complies with the IEEE C95.1-1991.

Warning: High intensity microwave may affect body health when operating high-intensity Radio Frequency (RF) equipment.

Conduct good coordination to shut down transmission on all antennas, tower, and/or mast before installation and maintenance operations.

Warning: Keep adequate distance away from the antenna when conducting installation and servicing operations around an operating antenna.

Avoid plugging the connector of the transmitter output feeder or of the antenna feeder during transmission.



Shut down the transmission before unplugging the connector of the feeder cable or working beside the transmitter antenna.

Laser Warning: Avoid looking straight at the laser beam from the outlet of the optical transceiver or inside the optical fiber to avoid an eye damage.

High Temperature Warning: Avoid touching the surface area of some devices due to high temperature to avoid a scald injury.

Fans Warning: Do not put fingers or any tools in the running fan to avoid an injury. Keep tools away from the running fan.

Sticking finger inside a running fan may cause hurt.

Put parts, screws, and tools away from the fan when replacing related parts, to avoid damage to the fan or related devices.

Keep fingers and board away from the fan when replacing devices around the fan, to avoid damage to the equipment or fingers.

Working at Heights Warning: Prevent objects form falling when working at heights.

Working at heights must conform to related service regulations:

Only a physically trained operator can work at heights.

Take care of the machinery and tools to prevent them from falling.

Take safety precautions and wear a helmet and safety belt.

Wear cold-protection clothes before working at heights in cold weather.



Check all hoisting equipment before working at heights.

Hoisting Heavy Objects Warning: Clear the area before hoisting heavy objects.

Ensure a proper hoisting capability of the hoister when disassembling heavy equipment moving, and replacing equipment. The operator must receive the training and qualification for hoisting operations. Inspect and complete the hoisting tools before getting into service. Make sure to fix the hoisting tools firmly on a sufficiently secured object or wall before the hoisting operation. Use brief oral instructions during the hoisting operations to prevent mistaken operation.

Plugging/Unplugging Modules Note:

Avoid inserting insert a module forcibly. Instead, align the module with the guide rail of the plug-in shelf and push it gently to the backplane. Push with proper force to align the guiding pin with the guiding hole in the backplane to protect the pins from bending.

Plug the module properly into the slot to prevent short circuit due to contact between the module and the circuit surface.

Avoid touching the circuits, components, connectors, and cable troughs when holding a module.

Personnel Note: Non-professionals can only perform maintenance inside the equipment with the presence or under instructions of professionals on site.

Replacing any parts or altering the equipment may result in unexpected dangers. Therefore, avoid replacing any parts or altering the equipment unless authorized.

Please contact ZTE if having any questions.

Installation of Power Cables and Grounding Cables


Brief Introduction to Power Cables and Grounding Cables

Installation of Power Cables

Equipment Grounding

Laying of Power Cables and Grounding Cables

Brief Introduction to Power Cables and Grounding Cables The power supply part of the ZXG10 BS21 includes PSM (AC) or DPS (DC), and external 220 V AC input or -48 V DC input, which form a complete set of power supply system for BS21.

External 220 V AC

The power cable comes from main line and goes to the 220 V AC power supply for ZXG10 BS21 with anti-lightning filter, and then distributes power to PSM and heat exchanger. PSM will perform AC/DC conversion, and then distribute power to CMM, ETRM, TMM, and heat exchanger. These modules, after various levels of DC/DC conversion supply power to the boards. At the same time, the ETRM also distributes +12 V output to AEM and provides overload disconnection protection for each module.

External -48 V DC

The power cable comes from main line and goes to the -48 V DC power supply for ZXG10 BS21 and distributes power to DPS to complete filtering and surge protection, and the heat exchanger does not work at the moment. Then DPS distributes power to CMM, ETRM, TMM, and heat exchanger.



The power supply and grounding cables are all led from the bottom of BS21, as shown in Figure 34. See Table 20 for the description of interfaces on the cabinet bottom.

Installation of Power Cables There are two types of power modules: AC power module and DC power module. Use different power supply plug-in box according to the configuration.

AC Power Cables The power supply plug-in box used for AC power supply is shown in Figure 13.

F I G U R E 13 P O W E R S U P P L Y P L U G - I N B O X (220 V AC)

The cross-sectional area of the power cable must be no less than 2.5 mm2

for external 220 V AC power supply. Connect the basic power from the L, GND, and N ends of the 3-core aeronautical socket on the cabinet bottom into the cabinet of the ZXG10 BS21 according to the polarity and grounding marks of the basic power, as shown in position 17 in Figure 34.

Note: Power cable colors: phase line (L) – red, zero line ground (N) – blue, protection ground (PE) – yellow/green

This equipment operates at 220 V AC, which makes the equipment potentially dangerous. Only a person with proper safety can enter a high-voltage.

Do follow the local safety regulations when installing any AC power equipment.

Anyone that installs AC equipment must be qualified for high-voltage and AC operations.

Do shut off power supply before connecting or disconnecting a power cable.

Make sure the cable and its label meet actual installation requirements before the installation.

According to power polarities, connect the power supply with ZXG10 BS21 cabinet through the 4-core aeronautical socket on the cabinet bottom plate, as shown in Figure 34 (the interface with the serial number 21).

Equipment Grounding The connectors marked as PE (protection ground of the case) and LPE (lightning protection ground) on the rack bottom of the ZXG10 BS21 must be grounded properly. The grounding connection is in good condition and the grounding resistance complies with technical requirements, less than 5 Ohm. Refer to positions 16 (PE) and 18 (LPE) in Figure 34 using 35 mm2 grounding wire for rack grounding connections.



1. Protection ground of the equipment

i. Install the protection grounding cable for the master equipment of the BTS. Connect the protection grounding cable of BS21 BTS to the protective grounding bar. Use plastic insulated copper-core wire with a cross section area no less than 35 mm2 s for this purpose.

ii. The protection grounding cables of the equipment must be copper conductors instead of aluminum conductors. The grounding terminal must undergo anti-corrosion and anti-rust treatment. Also, connect the grounding terminal securely.

iii. Protection grounding bar: The protection-grounding bar should have an independent grounding cable. Connect the grounding cable directly to the ground grid. It is preferable to adopt 4 mm × 40 mm of galvanized flat steel for the grounding down lead.

Note: Ground the equipment or facilities properly (e.g., lightning arrester for antenna feeder, lightning protection facility for transmission equipment). Connect the ground leads for the transmission equipment and antenna feeder directly with the ground grid via the busbar.

2. Grounding for the BTS installed on poles

i. The protection ground of the BTS must share the same grounding network with the lightning arrester.

ii. The connecting point between the BTS grounding cable and the grounding network must be within 3 m away from that between the anti-lightning arrestor cable and the grounding network (sharing the same network cable).

iii. The cables of the BTS system must be separate than the lightning arrester or the lightning arrester cables. Lay them far away from lightning arrester or the lightning arrester cables.

3. Grounding requirements of the antenna feeder system

Install lightning arrester with the BTS core module if the BTS uses the outdoor antenna.

Pay attention to following points during the installation:

i. Install the lightning arrester higher than the antenna and the antenna lies within 45° protection range of it.

ii. Ground the lightning arrestor to the ground network directly through flat steel.

iii. Ground the antenna feeder, power supply, and transmission to the busbar.

iv. Ground the equipment to the ground network through the protection ground bar.

4. All external cables for connections and grounding of the lightning arrest must have lightning protection before entering ZXG10 BS21.

Chapter 6 - Installation of Power Cables and Grounding Cables


i. Always ground the antenna feeder lightning arrester of the BTS. The cable must be made of plastic insulated copper-core wire with cross-section area no less than 35 mm2.

ii. The transmission equipment of the BTS must have lightning protection devices installed.

iii. The ZXG10 BS21 must have lightning protection devices installed to lead 220 V power supply and antenna feeders.

5. Other grounding

i. Take proper lightning-proof measures before leading the power and transmission lines into the equipment room.

ii. Ground the indoor system for indoor BS21 installation to the grounding bar and connect all equipment grounds to the grounding bar. Connect the grounding bar to general grounding bar of the building.

Laying of Power Cables and Grounding Cables Follow the principles below to lay power and grounding cables:

1. Laying power and grounding cable

i. They must be separate from other cables. Bind them separately instead of binding them as a bundle in the rack, also applying it outside the rack.

ii. Select the cable tie model (150 mm/300 mm) according to the cable quantity, and cut the cable tie even after binding.

iii. Measure the exact distance between the power distribution cabinet and wiring terminal of the cabinet during the cable distribution. Always reserve enough length for future insufficiency in practice. Replace the cable whose length is not long enough with a longer one and re-lay the cable. Avoid connecting or welding the cable with one another, as shown in Figure 16.

On-site cable connection is usually unnecessary, for they are ready before delivery. Make corresponding modifications with reference to contents in this section if the personnel change the site configuration during on-site installation.

Introduction to Backboard Interfaces Only the carrier shelf has backplanes in the cabinet.

The backboard transmission module (BTM) consists of an MMTRM, to transmit information among CMM, ETRM, and AEM. It also provides interfaces to input and output external signals.

Figure 17 shows the layout of MMTRM.

Settings of Basic and Extension Cabinets MMTRM backplane in BS21 (V2.2) cabinet uses two DIP switches, S1 and S2, for settings of cabinet ID.

DIP switch S1 and S2 are on the front of backplane, on which boards are inserted. Before setting DIP, pull out CMM board and dummy board first.

CMM reads the ID to determine the cabinet level (basic/extension), SDH network synchronization clock port, and O&M timeslot position upon power-on and initialization.

ID read by CMM is 0 when DIP switch is set to ON; otherwise, it is 1.

ID is a 16-bit serial number, as shown in Figure 27.

INDOOR: Type of BTS (0 - indoor and 1 - outdoor)

SYN: It synchronizes the network with reference clock source (0 - E1 interface abstracted clock, 1 – SDH synchronous clock) when INDOOR = 0. It indicates an outdoor station type (0 - BS21 station) when INDOOR = 1.

CHANEL_NO: It selects on-site monitoring equipment port when INDOOR = 0. It means an outdoor station type (00 - BS21 station) when INDOOR = 1.



BTS_NO: Rack No. in the same site (00 - Basic rack, 01-Extension rack 1, and 10- Extension rack 2)

SLAVE1_PORT: E1 port on the basic rack to connect extension rack 1 (BS21: 01 - D interface on the basic rack and 10 - E interface of the basic rack).

SLAVE2_PORT: E1 port on the basic rack to connect extended cabinet 2 (BS21: 01 - D interface on the basic rack and 10 - E interface of the basic rack).

SATE: It indicates to use the satellite Abis links (0 for ordinary Abis links and 1 for satellite Abis links).

ABIS_PORT: O&M port number (BS21: 00 – A interface and 11 – D interface)

ABIS_TS: O&M LapD timeslots on Abis interfaces (000 - Ts16, 001 - Ts31, 010 - Ts30, 011 - Ts29, 100 - Ts28, 101-Ts27, 110-Ts26, and 111-Ts25)

Note:

0: ON; 1: OFF, for DIP switches S1 and S2

Bit 1 ~ 8 of S1 represent bit 0 ~ 7 of the ID respectively, while bit 1 ~ 8 of S2 represent bit 8 ~ 15 of the ID respectively.

Basic rack E1 port connecting the lower-level station cannot be equal to the value of SLAVE_PORT1 or SLAVE_PORT2 when there is a lower-level station. For example, the basic rack D interface connects a lower-level station. Neither SLAVE_PORT1 nor SLAVE_PORT2 can be equal to 01.

Parallel Connection of Basic and Extension Racks Settings of Basic and Extended Racks The ZXG10 BS21 determines the basic and extension racks through their Ids. ID is the number of BS21 rack. Factory sets the cabinet ID and marks it clearly as below:

A/00 --------------- Basic rack

A/01 --------------- Extension rack 1

A/02 --------------- Extension rack 2



Parallel Rack Connection The rack for the ZXG10 BS21 connects a parallel rack by connecting synchronous cables and E1 cables between racks. Specific connections:

E1 cable connections:

Basic rack ABISO2--------Extension rack 1 ABISI1

Basic rack ABISI2---------Extension rack 1 ABISO1

Installation of Antenna Feeder System


Preparation for Antenna Feeder System Installation

Structure of Antenna Feeder System

Installation Flow of Antenna Feeder System

Installation of BTS Antennas

Check and Test of Antenna Feeder System

Waterproof Treatment for Connectors

Antenna feeder system of the base station includes I/O ports from BTS cabinet to BTS antenna. It mainly transmits and receives signals of the BTS. The system configuration with a tower top amplifier will require power lines for the tower top amplifier.

Configuration of BTS antenna system relates closely to network planning. Different coverage areas and environments needs different antenna feeder systems. Network planning has predetermined layout, elevation, dip, gain, and even diversity reception mode of the antenna before the installation.

Proper installation of antennas is essential to communication performance of coverage areas and to reliable operation of mobile BTS system. Install antennas in correct direction, including correct dip and azimuth of the antenna in each sector. Besides, antennas must be resistant to wind (i.e. capability to withstand wind at the speed of 150 km/h).

The below is sequence for antenna and feeder installation:

1. BTS antenna

2. Tower amplifier (optional)

3. Antenna jumper



4. Main feeder cable

5. Grounding card

6. Lightning arrester

Preparation for Antenna Feeder System Installation Engineering preparation is prior to the installation and it includes infrastructure construction, inspection of incoming materials, and preparation of cable connectors

Antenna installation parameters in networking planning, including directions of the antennas and specific distances between antennas in the same and different sectors, is essential.

Infrastructure Construction The grounding for the antenna, feeder, iron tower of BTS, and the equipment is extremely important. The work ground of BTS forms a combined grounding system with a grounding resistance less than 5 Ohm.

It is all right to install the antenna of the mobile system on the rooftop with or without fence, on an iron tower or pole. Make preparations, fix the supports and poles, and inspect the iron tower, poles, and cabling rack before installing antennas.

Iron Tower Check following items to ensure the safety of BTS:

1. Whether height, strength, and other indices of iron tower comply with the contract terms.

2. Whether copper grounding bars around the iron tower are ready and their grounding resistance complies with the contract terms.

3. Whether the platform of the iron tower is ready and meets the requirements.

Antenna Pole The pole is generally made of galvanized steel. Its outer diameter ranges 48 ~ 100 mm and the thickness of the pipe wall is no less than 2 mm and its reference length is 3 m. Actual size of the pole depend on requirements in the antenna description, for the antennas are of different types.

Check the following to ensure the safety of BTS:

1. Install antennas on poles spaced according to engineering design requirements. Horizontal diversity distance for 900 MHz generally

Chapter 9 - Installation of Antenna Feeder System


ranges from 4 m to 6 m while that for 1800 MHz ranges from 2 m to 3 m, for two receiving antennas in the same sector. Follow the design documents for otherwise specified designs.

2. Poles on the iron tower are mounted on the enclosure of flat roof, one meter away from the tower body.

3. Install poles used for fixing BTS antennas and are perpendicular to the horizontal plane (error less than ±1 degree).

4. Mount the poles close to the rooftop brink as much as possible. When securing the poles directly on the side of the wall, make sure that the wall is strong enough.

5. When securing the poles directly on the rooftop, construct cement frusta to avoid drilling holes on the rooftop, which may cause the rooftop leaking.

Cabling Racks Check the following to ensure the safety of BTS:

1. The cabling racks in the equipment room are all 400 mm-wide standard models, and are usually installed above the equipment rack about 2,600 mm above the floor. Make sure that the whole equipment does not shake after installation of the cabling racks.

2. The remaining length of the expansion bolts used for reinforcing must be the same, that is, reserve a length of about 5 mm or more than two threads when tightening the screw.

3. Paint the cabling rack with the same color.

4. Ground indoor cabling racks every 5 m. Measure electrically for proper grounding after installation.

Checking Incoming Materials Conduct inspection and performance test on the jumpers, tower top amplifier (optional), lightning arresters, and antennas before their distribution to the site.

Transport some materials directly to the site during installation of the antenna system of the BTS. Unpacking and inspection of these materials is also an important part of system installation. Such materials are main feeder cable, including installation accessories.

On-site inspection includes following items:

1. Check whether the packing is intact.

2. Carefully unpack to check the number of goods and accessories against the packing list.

3. Check the goods appearance for any damage.

4. Check the quantity (e.g. length) of the materials against the packing list for consistency.

5. Store the materials before installation.



Preparing Connectors All the cables use special connectors in the antenna feeder system.

Engineering personnel usually make jumper connectors before delivery and it is only necessary to make the connectors for feeders on the site.

Take the 7/8" feeder connector as an example. Procedures to make the connector:

1. Pull straight a section (about 150 mm) of the connector at one end, use a knife to strip off the sheath of the feeder cable 50 mm away from the end, as shown in Figure 36.

F I G U R E 36 S T R I P I N G O F F SH E AT H

Caution: Be careful when using the knife.

2. Strip the sheath of the feeder cable. Put the feeder cable end into the notch of the cutter, and make the notch as close to the sheath of the feeder cable as possible. Close the cutter gently and press it slightly. Turn the cutter clockwise, viewed from the feeder cable end, until the blade at the front cuts the internal and external conductors completely. Turn the cutter slightly two revolutions to make sure that the blade at the back cuts the sheath.

3. Put an O-shaped ring around the sheath of the feeder cable and apply lubricating oil at the first wave trough of the external conductor. Make the internally threaded end face outward and put the connector fastener around the feeder cable. Finally, push it in until it exposes a wave trough of the external conductor of the feeder cable, as shown in Figure 37.



F I G U R E 37 P L AC I N G O-S H A P E R I N G

4. Put the spring gasket into the wave trough of the external conductor of the feeder cable.

5. Press the foamed materials inside the feeder cable connector towards the internal conductor from the external conductor.

6. Guide one end of the plug-in component into the internal conductor of the feeder cable carefully and then load the plug-in component, as shown in Figure 38.

F I G U R E 38 C O N N E C T I N G

7. Turn the connector onto the fixing component. Turn the fixing component with a spanner without moving the connector. Brush the copper filings off the foamed material, especially the cross section of the foamed material, as shown in Figure 39.

F I G U R E 39 CL E AN I N G C R O S S S E C T I O N



8. Remove the connector and check the profile of the external conductor, which must be even without any foam or copper filings. Unscrew the plug-in component by 1/4 turns, and turn the connector fixing component while keeping the connector fixed, as shown in Figure 40.

F I G U R E 40 R O T AT I N G C O N N E C T O R F AS T E N E R

9. Screw the fixing component onto the plug-in component in the same way as described in step (7), as shown in Figure 41.

Structure of Antenna Feeder System Install up to three directional antennas or one omni-directional antenna on the top of the concrete pole.

Both transmission and reception can share one of the two directional antennas in a sector. Connect the duplexer and the combiner via the feeder cable. It transmits downlink signals from the BTS to the mobile station (MS) and receives uplink signals from the MS. The receiving of the uplink signals from the MS use the other antenna and connects directly to the pre-receiving filter via the feeder cable.

Each set of BTS antennas connects to the bottom rack via one feeder cable. Every feeder cable includes the following sections from the antenna to the antenna interface (specific feeder dimensions depend on site conditions) without tower amplifier configuration:

1. It consists of 1/2" super-flexible jumper from the antenna to the main feeder using a male DIN connector.

2. The main feeder is 7/8-inch feeder cable (including connectors on both ends). Generally DIN connecters, connecting the jumper of the main

feeder at one end, and the jumper from the main feeder to the super-flexible jumper at the other end.

3. There is a lightning arrester between the main feeder and the super-flexible jumper. It uses DIN connector for connection, with male end connecting the main feeder cable and female end connecting the jumper.

4. It is 1/2" super-flexible jumper from the main feeder to the MB, and it uses male DIN connector for connection.

5. There must be several grounding cards at the upper part and lower part of the main feeder cable before entering the equipment room. Space the grounding cards at 15 ~ 20 m with both ends grounded.

There is a jumper from the antenna to the tower amplifier and a jumper from the tower amplifier to the main feeder cable, in tower amplifier configuration.

The installation position and environment affects the installation of the antenna feeder system of the base station. Detailed installation procedures depend on installation environment.



Check the following to ensure the safety of BTS:

1. Ground the feeder cable properly at the platform on top of the tower after the installation of the BS iron tower on the floor, where the installed antenna is 0.5 m ~ 1 m above the bend. If the feeder cable is longer than 60 m, ground it in the middle. It connects the metallic outer layer to the grounding busbar via grounding clips. Lead out a tinplated copper wire with cross section area no less than 95 mm2 or zinc-plated flat steel of the busbar to connect corresponding grounding point of the iron tower.

2. Install antennas on poles spaced as per the engineering design requirements. Horizontal diversity distance of the 900 MHz one for two receiving antennas in the same sector generally ranges from 4 m to 6 m, while that of the 1,800 MHz one ranges from 2 m to 3 m. Follow the design documents for otherwise specified designs.

3. Reinforce the main feeder cable in every 1.2 m, and add some more reinforcement points at bends. The feeder must be closely against the pole, and it requires the reinforcement with the pole body every certain distance, as shown in Figure 45.

4. Ground the antenna and feeder properly. The work ground of the BTS should form a combined grounding system with a grounding resistance less than 5 Ohm. Ground the main feeder cable respectively where it connects with the antenna and where it leaves the bend of the iron tower.

The following contents detail the installation of the antenna feeder system based on the installation flow.



Installation of BTS Antennas The installation of antennas includes fixing the antennas, installing antenna jumpers, feeder cables, cabinet-top jumpers, lightning arresters, and grounding clips. Install the antenna with a lightning arrester if the BTS is an outdoor installation, and sometimes there may be no need to install lightning arresters.

Warning: Take care to prevent objects from falling while working at height.

Working at height should conform to the related national service regulation requirements:

Train people specially working at height.

Take care of the operation machinery and tools to prevent them from falling.

Take safety precautions, and wear helmet and safety belt.

Check all hoisting equipment before working at height.

Fixing Antennas Installation procedures of directional antenna and omni antenna are different. Pay attention to following aspects during both installations:

1. Only experienced professionals can install and maintain the antenna system of the BTS.

2. Read this manual and follow the specified procedures before installation.

3. Do not install antennas near any power line to ensure personal safety.

4. Do not use a metal ladder for installing antennas.

5. Wear safety belt and safety helmet for working at height.

6. Wear shoes with bossy rubber on the soles, wear rubber gloves, and wear jackets and long-sleeve shirts.

7. Never conduct any installation or test in rain, wind, moisture, or lightning weather.

8. Make sure that the BTS is off during installation.

9. Observe relevant precautions strictly during installation of every part.

It is necessary to use a rope to hoist the antennas to the right place before installation, as shown in Figure 46.



F I G U R E 46 H O I S T I N G AN T E N N A

Warning: Do not walk about right under the boom and hoisted weight.

Make sure of facilities with proper hoisting capability during disassembling, moving, and replacing equipment.

The personnel must have related training and corresponding qualifications for hoisting equipment. Check the hoisting tools to be complete. Make sure of fixed hoisting tools to a fixture that can bear the weight or to the wall for the hoisting. Use brief commands to prevent mistakes.

Directional Antenna The installation of directional antenna is a little complicated. Follow installation instructions of the antenna to install the antenna. General installation procedures:

1. Install the antenna fixing supports in a folded way, as shown in Figure 47.



F I G U R E 47 AN T E N N A S U P P O R T S

2. Adjust antennas to appropriate height. Use bolts and U-shaped bolts to fix the antenna dip fixing supports onto the antenna pole to ensure input/output ports of antennas face downwards, as shown in Figure 48.

F I G U R E 48 U-S H AP E B O L T

3. Verify the normal direction of the antenna radiation surface is the same as the antenna azimuth for network planning using compass. Turn the antenna centered by antenna pole. Adjust the azimuth of the antenna of adjacent sectors as required. Included angle between antennas of different sectors is generally 120°, while the directions of the two antennas within the same sector must be the same.

Install the antennas on the iron tower platform. It is difficult for an ordinary compass to define azimuth of the antenna accurately due to the influence of iron tower on the magnetic field. Use special instrument (e.g. Kathrein azimuth regulator as applied in the example here, as shown in Figure 49) to adjust the azimuth to designed degrees.

Omni-directional Antenna It is simple to install omni antenna.

1. Adjust antennas to appropriate height, use bolts and U-shaped bolts to fix the antenna onto the antenna pole to ensure that the input/output ports of the antennas face downwards, as shown in Figure 54.



F I G U R E 54 I N S T AL L AT I O N O F OM N I -D I R E C T I O N AL AN T E N N A

2. Make sure the antenna is vertical and measure it with a vertical angle gauge.

3. Tighten the screws with a spanner.

Installing Antenna Jumpers The antenna jumper is a 1/2" super-flexible jumper to connect the antenna and the main feeder cable in the BTS system. The use of jumper connectors depends on the antenna and the main feeder cable. They are usually male DIN connectors.


1. Select an appropriate path for the jumper, considering factors, such as, reliability, convenience, short jumper, and best water flow (i.e. the rainwater drops from the middle of the jumper and not from the connectors).

2. Connect the connector of the antenna and jumper with an appropriate torque (the connection torque of a DIN connector is typically 1.7 N·m and maximally 2.3 N·m). Make sure that the connector of the antenna and jumper does not bear any lateral force, as shown in Figure 55.



F I G U R E 55 C O N N E C T I O N O F J U M P E R S

3. Connect the connector of the main feeder cable and jumper with an appropriate torque (same as above). Make sure that the connector of the main feeder cable and jumper does not bear any lateral force.

4. Fix the jumper with feeder cable clips with the maximum spacing of no more than 0.76 m, as shown in Figure 56. Shorten the spacing between the feeder cable clips when the wind speed is over 160 km/h.

F I G U R E 56 F I X I N G FE E D E R C L I P

5. Measure the performance of the antenna and the feeder cable, make sure that the system works normally, and then seal connectors with waterproof self-adhesive tape and PVC tape.

Precautions when installing 1/2" super-flexible jumper, to ensure reliability of BTS antenna system.

1. Minimum bending radius of once-for-all bend is 125 mm, as shown in Figure 57.



F I G U R E 57 ON C E -F O R - AL L B E N D

2. Minimum bending radius of repeated bends is 200 mm, as shown in Figure 58.

F I G U R E 58 R E P E AT E D B E N D S

3. Tighten the connectors and seal them with waterproof adhesive tape if the test result of entire antenna feeder system is satisfactory.

Installing Feeder Cables Connect the main feeder cable with two jumpers (one to the antenna and the other to the cabinet) using 7/8" foamed feeder cable. Both connectors are usually female DIN connectors.

Ensure following mechanical properties when transporting and installing the main feeder cable:

1. Minimum bending radius of once-for-all bend is 400 mm.

2. Minimum bending radius of repeated bends is 450 mm.

3. Maximum feeder cable hoisting length of the hoisting trawl is 60 m.


1. The feeder cables delivered to the construction site are often very long without prepared connectors, so it is necessary to measure the required length of a single main feeder cable first during the installation (reserve excessive length), and cut the feeder cables delivered to the site into the lengths required.

2. Prepare the main feeder DIN connector at the antenna side.



3. Use pulley or hoisting trawl to lift the feeder cables to the iron tower, as shown in Figure 59. Work with several other people to fix the main feeder cables with feeder cable clips, and cut off remaining length of each main feeder cable.

F I G U R E 59 C AB L E H O I S T I N G M E S H

4. Proceed to main feeder DIN connector at the other side after installing the main feeder cable.

5. Reinforce main feeder cable every 1.2 m, and add some more reinforcement points at the bends. The feeder must be closely against the pole, reinforce with the pole body every certain distance, as shown in Figure 60.



F I G U R E 60 F I X I N G FE E D E R C AB L E S

6. Install BS iron tower on the floor. Ground the feeder cable properly 0.5 m ~ 1 m above the bend where it connects the antenna and leaves the tower body, and at the outside of the entrance to the equipment room. Ground it in the middle if the feeder cable is longer than 60 m. Connect its metallic outer layer to the grounding busbar via grounding clips, and lead out a tinplated copper wire with cross section area no less than 95 mm2 or zinc-plated flat steel of the busbar to connect to corresponding grounding point of the iron tower.

Precautions:

1. Keep the feeder cable (at least 150 mm) straight.

2. Use special-purpose tools for cutting feeder cables.

3. Measure the length precisely with an accurate ruler.

4. Use a knife to strip the sheath of the feeder cable without scratching the external conductor.

5. Keep the plug-in components motionless when tightening the connector with a spanner. Turn the connector-fixing component to fasten the connector firmly.

6. Attach identifiers to both ends of the main feeder cable before placing it onto the iron tower to distinguish sectors it belongs to and the transmitting/receiving features during line connection. Attach the identifiers closely to avoid peeling due to friction with the steel frame of the iron tower.

Installing Feeder Window Install the feeder window before introducing the feeder cable in the equipment room after installing BTS in the equipment room.




1. Drill holes at appropriate places on the wall of the equipment room, as shown in Figure 61.

F I G U R E 61 D R I L L H O L E S O N W AL L

2. Seal the feeder cable holes of corresponding number of feeder cables actually used, as shown in Figure 62.

F I G U R E 62 S E AL I N G FE E D E R C AB L E H O L E S

3. Figure 63 shows complete installation of the feeder window.



F I G U R E 63 I N S T AL L I N G FE E D E R W I N D O W

Installing Lightning Arrester Connect grounded lightning arresters in serial properly on all cables leading from the antenna of the BTS into the equipment room. Lightning arresters of different models from different manufacturers may differ. The following description takes typical λ/4 stub as an example.


1. Install the lightning arrester between 7/8" main feeder cable and 1/2" cabinet-top jumper after entering the equipment room. The lightning arrester has one male DIN connector and one female DIN connector. Maximum installation torque of the lightning arrester with DIN connector is 25 N·m, and that with N connector is 1.7 N·m. Please use an adjustable torque spanner to adjust the torque to specified value to prevent excessive torque from generating lateral force and damaging the lightning arrester.

2. The lightning arrester has one RF port connecting 7/8" main feeder cable and the other with 1/2" cabinet-top jumper. One may connect both RF ports with the antenna or BTS, and the lightning arrester provides the same protection against lightning, as shown in Figure 64.



F I G U R E 64 I N S T AL L I N G L I G H T N I N G AR R E S T E R

3. Connect grounding post of the lightning arrester to main grounding post or the system-grounding ring with small grounding resistance.

4. Do not seal connectors before performance test of feeder cable finishes. Seal the connectors with self-adhesive tape if test result is satisfactory, as shown in Figure 65.

F I G U R E 65 S E AL I N G L I G H T N I N G AR R E S T E R

Precautions:

1. Do not expose RF ports outdoors.

2. Make sure that all the grounding contact surfaces are clean, dry, and not oxidized during the installation.

3. Make sure to connect the grounding port of the lightning arrester with the main grounding rod or grounding ring of the system to secure small grounding resistance.

4. Install the lightning arrester properly and neatly.

5. Make sure that the operating frequency marked on the lightning arrester is compliant with operating frequency of BTS system.



Installing Grounding Clip The grounding clip serves to connect external conductor of the feeder cable with the tower or independent grounding wire to channel the current into the ground in case of lightning stroke. One must install the grounding clips at the top of the feeder cable near the antenna, at the end of the feeder cable near the tower bottom, and before the feeder cable enters the equipment room. Connect a grounding clip to the middle of a feeder cable longer than 60 m.


1. Fix the grounding end of the grounding clip. Mark the corresponding position on the 7/8" feeder cable at the installation position of grounding clip, and strip the sheath of the 7/8" feeder cable at the installation position to install the grounding clip.

2. Put the retaining ring of the grounding clip around external conductor of the feeder cable and snap the ring, as shown in Figure 66.

3. Use waterproof self-adhesive tape to wind around entire connection place. Each layer overlaps half of last layer is as shown in Figure 67. The winding direction must be the same as bail direction to make the connection tighter. Press adhesive tape along the edge of grounding clip to make the tape fit in closely with retaining ring of the grounding clip.

4. Use electrically insulated tape to wind around entire connection place. Wind in semi-overlapping mode to leave a length of 25 mm for each layer over its previous layer, as shown in Figure 68. Overlap the electrically insulated adhesive taps by half. Pull the tape to a proper length to avoid folding. Wind backward when it comes to the end of connection place. Press the tape with both hands to make sure that layers are in good contact.

F I G U R E 68 E N W I N D I N G E L E C T R I C AL I N S U L AT I N G T AP E



5. Connect grounding end of the grounding clip to the tower body or special-purpose wiring post. Remove the paint and oxide about 13 mm around the connection place. Apply antioxidant grease to the clean area to ensure proper electrical contact.

Warning: Do not install grounding clip in case of lightning strike to avoid personal injury.

Notes: Make sure to ground the external conductor of the feeder cable properly at the position of the grounding clip.

Make sure to seal the external corrugated conductor of the feeder cable completely (waterproof, airtight, and antioxidant) after installing the grounding clip.

Installing Cabinet Jumper Connect the cabinet and the main feeder cable by a 1/2" super-flexible feeder cable. The use of jumper depends on the cabinet and the main feeder cable. Both connectors are usually male DIN connectors.


1. Unfasten the four installation bolts to fix the antenna feeder socket (one among HYCOM1 ~ HYCOM6) on the cabinet top, and screw off the socket.

2. Unfasten the N connector on AEM, loosen RF cables on AEM panels and adjacent ETRM, and unfasten spring screws to remove AEM and adjacent ETRM.

3. Put the jumper down from the cabinet top to corresponding carrier frame. Grab the jumper at the hole on the side panel of the frame, and thread it out from the hole on front post of the cabinet.

4. Take the N connector out from the baffle plate. Adjust the direction of the N connector so that its cross section faces inward and points to the module panel. Tighten the four screws on the cabinet top to secure the antenna feeder cable.

5. Plug AEM and ETRM again, connect RF cables on the panels, and tighten all the connections.

Note: Refer to installation of antenna jumpers in Section “Installing Antenna Jumpers” for related precautions.



Check and Test of Antenna Feeder System Perform the antenna feeder test to match the feeder cable, that is, to verify correct installation and proper function of the antenna feeder system. This test mainly involves the indices of the receiver and the transmitter. Main test items are Standing Wave Ratio (SWR) and RF transmitting power.

Preparations Requirements before testing the antenna feeder system:

1. Install antenna and feeder cables and disconnect interfaces connecting the antennas.

2. Check for any damage to the feeder cable, proper connection, and correct direction of the antenna.

3. Arrange the test process to avoid repeated connection and disconnection of connectors and sealed parts. Do not seal connectors with adhesive tapes before the test is complete.

People’s safety might be in danger to stay close to the antenna because it may generate electromagnetic radiation. Only qualified professionals with adequate training may install and service the equipment. The radiation design of the equipment must comply with IEEE C95.1-1991 standard.

Warning: The high intensity microwave may affect body health when operating on high-intensity RF equipment.

Collaborate to shut the transmitter of the antenna down when doing close installation and maintenance operations on a certain antenna in an iron tower or mast mounted with many transmitter antennas.

Warning: Keep adequate distance from the antenna when conducting installation and servicing operations around the operating antenna.

Avoid unplugging the connector of the transmitter output feeder or of the antenna feeder cable during transmission.

Power off the relevant transmitter before unplugging the feeder cable connector or working beside the transmitter antenna.

VSWR Test VSWR test refers to the test of VSWR (Voltage Standing Wave Ratio) of TX antenna. The BTS tester SITE MASTER 332B is better for the test. VSWR must be less than 1.5. Check the antenna feeder system if VSWR test result is not OK:



1. Check the connection of connectors.

2. Check for any scratches or damages to the surface of the feeder cable, and bending radius of the feeder cable to be smaller than permitted minimum value.

Fill in Installation Acceptance Report and BTS Information Table after the test finishes, and the user signs it for acknowledgement.

The system gives an alarm if VSWR exceeds 1.5 after BTS system installation. There are two alarm thresholds in the system. The system generates an alarm when it overruns primary alarm threshold, and BTS keeps operating. The transmitter shuts down automatically when it overruns the secondary alarm threshold.

RF Transmitting Power Test RF transmitting power refers to average RF carrier power, and it determines the power at input end of the combiner and verifies accuracy of average transmitting RF carrier power.

Use on-site test instruments and BTS tester MASTER 332B is better.

Conduct the test at the input end of the combiner, like output end of the power amplification module.

BS21 must be able to output maximum peak power of the power levels, as shown in Table 36 (RF900) and Table 37 (RF1800) and accordingly turn down 6 static power levels at a step of 2±0.5 dB.

Waterproof Treatment for Connectors Seal the connectors after the completion of the system test for antenna feeder and the results are OK. Use two types of adhesive tapes for sealing: waterproof self-adhesive insulated tape and electrically insulated adhesive tape. Wrap the connectors with electrically insulated adhesive tapes, then with the waterproof adhesive tapes, and finally with electrically insulated tapes again.

The electrically insulated adhesive tapes must be fire-retardant, coldness resistant and corrosion-proof, and must be able to operate under voltage of 600 V. Its operating temperature must not be greater than 80°C.

Following describes usage of electrically insulated adhesive tapes:

1. Polish the surface area and clean it.

2. Remove the lining paper of the adhesive tape, to make the glued side face the surface to be covered.

3. Wind the tape continuously in a half-overlap way, to keep the tape fully stretched.

Power-on/off


Unplugging/plugging Modules

Check before Power-on

Power-on/off Procedures

Unplugging/Plugging Modules Installation and maintenance personnel must avoid hot plugging of modules in BS21 system to avoid unnecessary human damage to the modules.

Notes: Do not plug a module with great force to avoid bending the pins on the backplane.

Plug the module right into the slot and avoid contact between the module and the circuit face.

Do not touch the module circuits, components, connectors, and wiring slots when holding a module.

Wear antistatic wrist strap for necessary hot plugging.

Notes: Static electricity produced by human body may damage static-sensitive components on the circuit board, such as large-scale integrated circuits (LSI).

Accumulated electrostatic charges (ESC) derive from friction created by human body movements. Human body can carry a maximum of 30 kV static voltage in a dry environment, which could remain on human body for a long time. An operator carrying static electricity may discharge electricity through the component when touching a component, causing damage to it.

Wear an antistatic wrist strap in order to prevent human static electricity from damaging sensitive components. Ground the other end before



touching any equipment or holding a plug-board, circuit board, IC chip, and others.

Plugging Modules 1. Hold the panel of the module with both hands and keep it level. Insert

the module into the corresponding slot of the shelf, as shown in Figure 69.

F I G U R E 69 P L U G G I N G M O D U L E

2. Push the board slowly until it contacts the backplane. Press down the

interface module slightly to connect its connector firmly to connection socket of the switch. Fasten screws on the panel of the module. Figure 70 shows the effect after completion.

Chapter 11 - Power-on/off


F I G U R E 70 MO D U L E I N S E R T E D

Unplugging Modules Unscrew fastening screws on the panel, and pull the module out of the slot gently.

Precautions:

1. Avoid hot plugging/unplugging

ZXG10 BS21 (V2.2) adopts separate power supply and takes protective measures on the circuit for the module power supply for hot swapping. However, components like power sockets can withstand only a limited times of electric surge, to avoid hot plugging/unplugging.

2. Disconnect corresponding circuit breaker in PSM before installing a module into the cabinet, push the module along the guide rail, and close the circuit breaker.

Disconnect corresponding circuit breaker in PSM before dismounting the module from the cabinet, and pull out the module along the guide rail. Keep the circuit breaker disconnected during the whole process.

Check before Power-on Check carefully before powering on BS21 after BS21 (V2.2) hardware installation finishes. Check items:



1. Whether to match plug-in modules installed on the rack with desired configurations.

2. Whether every module is in position and in good contact. Unplug and plug it again if necessary.

3. Whether connections of cables between layers of same rack and between different racks (including cables of the backplane) are correct and reliable.

4. Whether connection of cables between BS21 and BSC is proper.

5. Whether power input is correct and power voltage is within the permitted range (nominal AC value: 220 V, permitted fluctuation: 130 V ~ 300 V; nominal DC value: -48 V, permitted fluctuation: -57 V ~ -40 V).

6. Whether installation of antenna feeder is correct. Note which cell the antenna feeder belongs to and avoid any wrong connection. Check whether introduction of any simulation loads if TX transceiver is idle. Take special care to check that the cable from ETRM module to AEM unit module and the cable from AEM unit to the antenna is correct, to prevent any radiation leak.

7. Whether groundings for racks, antennas, and lightning arresters are correct.

8. Whether nominal values of installed fuses match specifications.

9. Whether set various selecting and controlling switches of the equipment at the specified start positions.

Caution: Check power and equipment switches carefully to prevent human injury or damages to the equipment.

Power-on Procedures Power-on/off procedures:

1. Check to confirm that various power modules are in “Off” status.

2. Turn the cabinet-top power switch to “ON” status.

3. Turn on the modules by turning on corresponding open circuit protective switches of modules on PSM panel in order. Observe normal response from the indicators on the panel after power-on. Locate and clear the faults immediately, if not. Figure 71 shows PSM panel.
