2.3.2 Grounding Requirements Proper grounding ensures stable operation of the equipment. Proper grounding is also the prerequisite for the access network to be protected from thunder strikes or interference. Carefully check the grounding conditions on site to ensure proper grounding.

To protect the equipment from a lightning discharge, the earth resistance of the grounding system is recommended to be less than 10 ohms. The equipment grounding should also be in accordance with the national and local electrical codes.

2.4 Unpacking and Inspecting This section describes how to unpack and inspect items from the following aspects:

Requirements for Unpacking Unpacking the Wooden Case Inspecting Items Inside the Wooden Case Unpacking the Carton Inspecting Items Inside the Carton

2.4.1 Requirements for Unpacking After the project kicks off, the project supervisor along with the customer must check the products.

The project supervisor must ensure that:

The total number of products is consistent with the number of products on the packing list attached to the packing case.

The destination mentioned in the packing list is the actual installation site. The packing case is in good condition. The cabinet is placed correctly.

If the outer package is damaged or wet or the equipment is wet and rusty, stop unpacking and find out the reason. Give feedback to the Huawei local office about the damaged equipment.



To protect the equipment and to find out the reason for the damage, store the unpacked

equipment inside the equipment room. Take photos of the storage environment, the rusted or corroded devices, and the packaging

cases and materials. Archive the photos. Take good care of the unpacked packaging cases and materials.

If the products are in good condition, unpack and inspect the items. Unpack the case labeled Built-In Packing List, and take out the packing list. Check the products in the case according to the Packing List.

If any product is less or if any wrong product has been delivered, fill in the Article Problem Feedback Form. In case of any damage to articles, both the parties must fill in the Cargo Replacement Application Form and sign the Packing List.

Prevent the equipment, components, or parts from colliding with doors, walls, or shelves

during transportation and handling. Do not touch the uncoated surface of the equipment, parts, or components with sweat

soaked or dirty gloves.

2.4.2 Unpacking the Wooden Case

Do not place the wooden case upside down. Otherwise, the equipment will be severely damaged.

Wooden cases are used to pack heavy objects such as racks and batteries. Generally, a rack is packed with wooden boards, steel edges, tongues, and foamed angle wraps.

Move the packing case into or near the equipment room (if possible) to avoid damage to the cabinet during transportation. To unpack the case, do as follows:

Step 1 Insert one end of the ejector lever into a hole of the tongue on the cover of the wooden case.

Step 2 Turn the ejector lever to straighten the tongue, as shown in Figure 2-1. You can also use a screwdriver or a hammer to straighten the tongue.

Figure 2-2 Removing the cover

Step 4 Straighten all the tongues that join the wooden boards around the wooden case and remove the wooden boards, as shown in Figure 2-3.



----End

Figure 2-3 Removing the wooden boards

Unpack other cases in the same way.

When handling the cabinet, hold the strong places such as the upper cable rack or bone frame. Do not use too much force on places that are not firm, such as cable supports, cable fixing-beams, to avoid any damage to the cabinet.

Remove the lining board of the rack on the installation site. Otherwise, boards and signal cables may be damaged during transportation.

2.4.3 Inspecting Items Inside the Wooden Case After unpacking, check the items inside the wooden case to ensure that:

The appearance of the cabinet is not damaged. The front and the rear doors of the cabinet match. The top of the cabinet is in good condition and the marking is legible. The dummy panels and nameplates of boards in the subracks are installed. The sanitation inside the cabinet meets the requirements. The feeder clips and other items are complete and in good condition.

The items checked must be placed in order.




2.4.4 Unpacking the Carton Generally, cartons are used to pack boards, modules, or terminal devices.

After moving a board from a dry place with lower temperature to a wet place with higher

temperature, wait at least 30 minutes before unpacking. Otherwise, humidity may gather on the surface of the board and cause damage to the equipment.

When unpacking the boards, take antistatic measures to prevent the boards from being damaged.

When cutting the tape using a paper knife, take care not to cut too deep. Otherwise, the items inside may be damaged.

Keep the carton and antistatic plastic packing bags for future use such as holding spare parts or parts sent back for repair.

Unpack a carton, as shown in Figure 2-4.

Figure 2-4 Unpacking a carton

3.1.3 Casting the Cement Plinth

Confirm whether a cable passage should be reserved according to the on-site cabling before casting the cement plinth. The dimensions and locations of the cable passage should be provided by the customer.

Cast a cement plinth based on the dimensions shown in Figure 3-3.

The height of the cement plinth must meet the flood protection requirement in the local area. The cement plinth should be at least 200 mm higher than the ground surface. This helps to protect the cabinet from damage in the case of heavy rain or flood.

Ensure that the smoothness error of the upper plane is not more than 5 mm.

3.1.5 Drilling Holes and Installing Expansion Bolts

The expansion tube must be completely buried in the ground. The depth of the hole must range from 52 mm to 60 mm. The depth of the hole must be the

sum of the length of the expansion tube and the length of the drill bit. If the depth is less than 52 mm or more than 60 mm, the expansion bolt cannot be fastened.

All the holes must have the same depth. Before measuring the depth of the hole, remove the dust inside the hole to measure the correct depth.

After drilling the holes, measure the distance between the holes. If a drilled hole is of great deviation, relocate and drill a new hole.

To drill a hole and install the expansion bolt, do as follows:

Step 1 Use the φ16 drill bit and the M12 expansion bolt assembly.

Figure 3-5 shows the M12 expansion bolt assembly.

5.2 Preparations Before installing the boards, do as follows:

Wear an antistatic wrist strap, and connect the ESD plug to the ESD connector on the cabinet, as shown in Figure 5-2. Ensure that the wrist strap is in good contact with your wrist.



If the cabinet is not grounded, first connect the PGND wiring terminal on the left of the cabinet to

the external grounding bar. For details, see section 7.3 "Installing the PGND Cables." Keep the ESD wrist strap in good condition. Its resistance should be between 0.75 Mega ohms and

10 Mega ohms. Generally, the life expectancy of the ESD wrist strap is for about two years. Replace the strap when the resistance falls below the specified range.

Figure 5-2 Wearing an antistatic wrist strap

(1) ESD connector (2) ESD plug (3) Antistatic wrist strap

The antistatic wrist strap cannot prevent static electricity from being generated by friction between a board and your clothes. Ensure that the boards are not touching your clothes.

Clean the subracks. Check whether there are any bent, missed, or broken pins on the backplane.

− If there is any bent pin, replace it. In case of an emergency, straighten it with a pair of nipper pliers.

− If any pin is missing, replace the backplane. Check whether the sockets on the backplanes and the boards are deformed.

− If the deformation is not visible, adjust the socket using a pair of nipper pliers. − If the deformation is serious, replace the backplane or the board.

Prepare a #2 crossover screwdriver whose diameter is 6 mm to tighten the M3 captive screws on the board panels.

Keep the boards or parts that are not installed in antistatic bags. Place the removed boards or parts on the antistatic pad or on other antistatic materials. Do not pack or hold the boards or parts using plastic foams, common plastic bags, or paper bags.

If you are not clear about the specifications of the screwdrivers, try different screwdrivers until you find a suitable screwdriver.

5.4.2 Selecting Air Breakers for AC Input The principles of selecting air breakers for AC input in the BTS3012AE cabinet are as follows:

Determine the capacity of the air breakers based on the number of the PSUs configured in the BTS3012AE cabinet.

Consider the output power of the PSU based on the maximum typical power (2,000 W) of the heat exchanger and the maintenance socket.

Table 5-2 lists the specifications of the air breakers for AC input in the BTS3012AE cabinet.

Table 5-2 Specifications of the air breakers for AC input in the BTS3012AE cabinet

Number of PSUs 2 3 4

PSU Output Power 3,360 W 5,040 W 6,720 W

Recommended Capacity of Single-Phase Air Breakers

63A 63A 100A

Recommended Capacity of 3-Phase Air Breakers

3×32A 3×32A 3×63A or 3×32A

If the BTS3012AE cabinet is configured with four PSUs, whether to choose 3-phase air breakers with the capacity of 3×63A or those with the capacity of 3×32A is related to the position of the PSUs.

If two out of the four PSUs are placed at L2, choose 3-phase air breakers with the capacity of 3×63A.

If any two PSUs are not placed in the slots PSU1 and PSU5, choose 3-phase air breakers with the capacity of 3×32A.

Select air breakers according to the capacity range listed in Table 5-3. In case of 3-phase AC input, evenly connect the PSUs to be configured with three cables. If the capacity of the air breaker is over-small, tripping may occur.

5.5 Installing the DELU 5.5.1 Installation Overview

The DELU is in the signal lightning protection subrack. It is configured in slots 0 of the DSCB (from top to bottom). The BTS3012AE requires a minimum of one DELU.

One DELU can protect four channels of E1 signals from lightning strike.



5.5.2 Installation Procedure The procedure for installing the DELU is as follows:

Step 1 Keep the DELU flat.

Step 2 Hold the left and right sides of the DELU with your hands and place it in the slot.

7.2 Installing the Power Cables

Do not connect the N wire of the AC power cable to the PGND cable of the exchange equipment or communication equipment.

7.2.1 Introduction to the Power Cables The BTS3012AE supports the following power input modes:

220 V AC 3-phase 4-core input 220 V AC single-phase 2-core input 110 V AC dual-live input

Table 7-3 lists the specifications of the AC power cables for the BTS3012AE in different input modes.

Table 7-3 Specifications of the AC power cables for the BTS3012AE

Power Input Mode Core Wire Core Quantity Sectional Area Color

L 3 10 mm2 Red 220 V AC 3-phase 4-core input

N 1 10 mm2 Black

L 1 16 mm2 Red 220 V AC single-phase 2-core input N 1 16 mm2 Black

L 2 16 mm2 Red 110 V AC dual-live input

N 1 16 mm2 Black

The AC power cables for the BTS3012AE are available at local markets. The colors of the cables

must comply with the local rules and regulations. If the local rules and regulations have no special requirements pertaining to the color of the cable, use the cables that are delivered with the BTS.

The default color of the delivered L wire is red and the default color of the N wire is black. The OT terminals of AC power cables are made on site.

For details, see Table 1-7 "Types and installation positions of the cables."

Table 7-4 lists the rated voltage, rated frequency, and power distribution mode in different modes.



Table 7-4 AC power distribution mode

Rated Voltage (V AC) Rated Frequency (Hz) Power Input Mode

200–250 ! 20% 45–65 220 V AC single-phase 2-core input

346/200–433/250 ! 20% 45–65 220 V AC 3-phase 4-core input

208/120–220/127 ! 20% 45–65 110 V AC dual-live input

Note: For example, if the rated voltage is 346/200 V AC, the circuit voltage is 346 V AC and the phase voltage is 200 V AC.

7.2.2 Installation Principles Adhere to the following principles when installing the power cables:

The power cables must be cut according to the measured distance between the wiring terminals and the power interface box. Extra length must be reserved.

If the power cable is of insufficient length, replace it with a new power cable. Do not make connectors, or solder joints.

The power cables must be separated from other power cables. If the power cables are laid parallel to the other power cables, the space between them

must be at least 30 mm. The power cables tied on the metal cabling rack must be insulated. Switches or fuses must not be added to the power cable. The E1 cables must be laid neatly and tied with cable ties. The space between the cable

ties must be 200 mm. The cable ties must be in one line and in the same direction. The ends of the cable ties

must be evenly cut.

It is difficult to move the slide plate in the storage battery cabin after the power cables are led into the cabinet through the waterproof module. Therefore, keep the cable slack.

7.2.3 Leading the 3-Phase 220 V AC Power into the BTS3012AE Cabinet

To lead the 3-phase 220 V AC power into the BTS3012AE cabinet, do as follows:

Step 1 Remove the cover of the filtering box.

Take care not to damage the power cables connected to the socket on the cover.

Step 2 Determine the hole (in the waterproof module) through which the power cable is routed into the cabinet.

Step 3 Cut the cable according to the measured distance between the power interface box and the wiring terminals N, L1, L2, and L3.

Step 4 Attach temporary labels to both ends of the cable.




The contents of the temporary labels can be the same as the contents of the formal ones or decided on site.

Step 5 Lay the cables. For details, see section 7.2.2 "Installation Principles."

Step 6 Make an OT terminal at one end of the external power cable.

Step 7 Lead the L1, L2, L3, and N wires with OT terminals into the cabinet through the waterproof module. Secure the OT terminals to the wiring posts, as shown in Figure 7-8.

The labels must be attached 20–50 mm away from each end.

----End



7.2.4 Leading the Single-Phase 220 V AC Power into the BTS3012AE Cabinet

Ensure that the L wire and N wire are connected correctly in single-phase mode. If not, the lightning arrester may be burnt, causing serious faults.

The two methods used to lead the L wire into the BTS3012AE cabinet in single-phase mode are as follows:

The single-phase power provided by the customer is divided into three channels in the power interface box before being led into the BTS3012AE. For details on how to connect the cables, see section 7.2.3 "Leading the 3-Phase 220 V AC Power into the BTS3012AE Cabinet."

Install a short-circuiting copper busbar on the AC lighting arrester. Lead the single-phase power provided by the customer directly into the BTS3012AE. For details on how to connect the cables, see section 7.2.3 "Leading the 3-Phase 220 V AC Power into the BTS3012AE Cabinet."

7.3 Installing the PGND Cables 7.3.1 Introduction to PGND Cables

The yellow and green PGND cables of the BTS3012AE have a cross-sectional area of 25 mm2. Choose plastic insulation copper core cables with a cross-sectional area of at least 25 mm2 if you prepare the PGND cables by yourself.

The yellow and green PGND cables of the transmission interface box and power interface box have a cross-sectional area of 16 mm2. Choose yellow and green plastic insulation copper core cables with a cross-sectional area of at least 16 mm2 if you prepare the PGND cables by yourself.

7.3.2 Installation Principles Adhere to the following principles when installing the PGND cables:




Measure the accurate distance between the two grounding ends and reserve cables according to the distance. When laying out the PGND cables, replace the cables if the reserved cables are not long enough. Solder joint or connection is not allowed.

The PGND cables must be separated from other PGND cables. If the PGND cables are laid parallel to other PGND cables, the space between the PGND

cables and the other cables must be at least 30 mm. If PGND cables need to be bound with the metal cabling rack before being laid out,

insulation measures should be taken. Switches or fuses cannot be added to the PGND cable. The connection points at both ends of the PGND cables should be in good electrical

contact and anticorrosion measures should be taken. The E1 cables must be laid neatly and tied with cable ties. The space between cable ties

must be 200 mm. The cable ties must be in one line and in the same direction. The ends of the cable ties

must be cut evenly.

The PGND cables after being routed into the cabinet through the waterproof module may prevent the removal of the slide plate from the storage battery cabin. To ensure that the slide plate can be moved in and out freely, keep enough redundant length of the cables that have been routed into the cabinet through the waterproof module.

7.3.3 Installation Procedure To install a PGND cable, do as follows:

Step 1 Determine the hole (in the waterproof module) through which the PGND cable is routed into the cabinet.

Step 2 Measure the distance between the internal grounding bar of the BTS3012AE and the wiring terminal of grounding bar outside the cabinet according to the actual cabling route of the PGND cable. Obtain a cable of proper length.

Step 3 Attach temporary labels to both ends of the cable. The contents of the temporary labels can be consistent with the contents of the formal ones or can be determined based on your requirements.

Step 4 Lay out the PGND cable according to the specification requirements for cabling and the cabling mode required for the project. For the basic cabling principles of PGND cables, see section 7.3.2 "Installation Principles."

Step 5 Make OT terminals for the PGND cable.

Step 6 Route the PGND cable into the cabinet through the waterproof module. Connect one end of the PGND cable to the grounding busbar in the cabinet, and secure the OT terminal using a spring washer and a screw.

When fixing the waterproof module to the bottom plate of the cabinet, you should apply lubricants. The applying method is the same as that is described in section 7.2 "Installing the Power Cables."



Step 7 Connect the other end of the PGND cable to the grounding copper busbar outside the cabinet.

Step 8 Attach formal labels 20–50 mm away from both ends and remove the temporary labels.

----End

7.3.4 Connecting the PGND Cable to the Transmission Interface Box

To connect the PGND cable to the transmission interface box, do as follows:

Step 1 Measure the distance between the grounding bar of the transmission interface box and the wiring terminal of grounding copper bar outside the cabinet according to the actual cabling route of the PGND cable. Obtain a cable of proper length.

Step 2 Attach temporary labels to both ends of the cable. The contents of the temporary labels can be consistent with the contents of the formal ones or can be determined based on your requirements.

Step 3 Lay out the PGND cables according to the specification requirements for cabling and the cabling mode required for the project. For the basic cabling principles of the PGND cables, see section 7.3.2 "Installation Principles."

Step 4 Strip the outer insulation layer on one end of the PGND cable.

Step 5 Loosen the adjustment screws on any free cable clamping interface of the grounding bar in the transmission interface box. Insert the cable wire that is stripped of insulation layer into the cable clamping interface of the grounding busbar, and then fasten the adjustment screws.

Step 6 Make an OT terminal at the other end of the PGND cable.

Step 7 Fix the end with an OT terminal on the grounding copper bar outside the cabinet.

Step 8 Remove the temporary labels at both ends of the cable and attach the formal labels.

----End

7.3.5 Connecting the PGND Cable to the Power Interface Box To connect the PGND cable to the power interface box, do as follows:

Step 1 Measure the distance between the grounding bar of the power interface box and the wiring terminal of grounding copper bar outside the cabinet according to the actual cabling route of the PGND cable. Obtain a cable of proper length.

7.4.2 Installation Principles Adhere to the following principles when installing the E1 cables:

The E1 cables must not be routed on the outdoor cabling rack. The E1 cables should pass through a metal tube whose ends are grounded. Alternatively,

the E1 cables with metal sheath are used with both ends grounded. The E1 cables must be separated from the other cables. If the E1 cables are laid parallel

to the power cable, PGND cable, or RF signal cable, the space between the E1 cables and the other cables must be greater than 30 mm.

The bending radius of the coaxial cable must not be less than 40 mm so that the wires in the cable will not be damaged.

The E1 cables must be laid neatly and tied with cable ties. The E1 cables must not be stretched at the bend. The cable ties must be in one line and in the same direction. The ends of the cable ties

must be evenly cut.



7.4.3 Installation Procedure

If the E1 cables have outer shielding coat, strip the cables at the positions where the cables are led into or out of the cabinet. If the E1 cables do not have outer shielding coat, no processing is required.

To install the E1 cables, do as follows:

Step 1 Determine the hole (in the waterproof module) through which the E1 cable is routed into the cabinet.

Step 2 Cut the E1 cable to a proper length according to the cabling route.

Step 3 Lay the E1 cables outside the cabinet. For details, see section 7.4.2 "Installation Principles."

Step 4 If the E1 cables have outer shielding coat, strip the cables at the positions where the cables are led into or out of the cabinet. If the E1 cables do not have outer shielding coat, no processing is required.

Step 5 Lead the E1 cable into the waterproof module and route the cable along the column to near the DB25 socket of the DELU.

Step 6 Connect the DB25 connector to the DELU according to the label on the E1 cable.

Step 7 Connect the other end to the transmission interface box.

Step 8 Attach labels 20–50 mm away from both ends of the E1 cable.

----End

7.4.4 Connecting the 75-ohm E1 Cable to the Transmission Interface Box

To connect the 75-ohm E1 cable to the transmission interface box, do as follows:

Step 1 Install an SMB connector to one end of the E1 cable.

Step 2 Lead the 75-ohm E1 through the cable access socket into the transmission interface box. Install the cable on the 75-ohm digital unit, as shown in Figure 7-17.

Step 3 According to Steps 1 and 2, install the customer-prepared E1 cable to the other side of the 75-ohm digital unit and tie the cable to the bundling socket using cable ties.

Step 4 Fill the gaps of the cable access socket with waterproof mud.

----End

7.4.5 Connecting the 120-ohm E1 Cable to the Transmission Interface Box

To connect the 120-ohm E1 cable to the transmission interface box, do as follows:

Step 1 Remove the indicator card from the 120-ohm digital unit.

Step 2 Cut a proper length of the 120-ohm E1 cable.

Step 3 Lead the 120-ohm E1 cable through the cable access socket into the transmission interface box.

Step 4 Select the wires for the 120-ohm E1 cable according to the cable connection list delivered with the cables. Select the cores for the 120-ohm E1 cable.

Two signal transfer cables and one grounding cable form a group. One group provides one uplink or downlink E1 channel.

Step 5 Lead the wires through the entrance of the cable trough on one side of the 120-ohm digital unit into the cable clamping interface, one group for one cable trough, as shown in Figure 7-18.

7.5 Installing the Optical Fibers 7.5.1 Introduction to the Optical Fibers

The BTS3012AE uses both multimode fibers and single-mode fibers.

The optical fibers in the BTS3012AE are LC connectors, as shown in Figure 7-21.

Figure 7-21 LC connector

1

(1) Heat-shrink tube (2) Tail wire (3) LC connector

The color of the PVC sheath of a multimode fiber is orange and the color of the PVC sheath of a single-mode fiber is yellow.

7.5.2 Installation Principles Adhere to the following principles when installing the fibers:

The E1 cables must be laid neatly and tied with cable ties. The fibers must not be stretched at the bend. The bending radius must be greater than or

equal to 20 times the diameter. Do not pull the fibers or trample on the fibers and prevent them from touching sharp

objects. Check whether there are creases and impresses on the fibers, and damages to the

connectors. If yes, replace them with fibers in good condition. The rest of the fibers must be coiled on the fiber coiler. The fibers outside the cabinet must be protected with PVC corrugated tubes. The connectors, if not used, must be covered with dustproof caps. The cable ties must be in one line and in one direction. The ends of the cable ties must be

evenly cut.




Do not look into end faces of the connectors if one end of the fiber is connected to the optical transmission device. This is to prevent injury to the eyes.

7.5.3 Installation Procedure To install the fibers, do as follows:

Step 1 Determine the hole (in the waterproof module) through which the fiber is routed into the cabinet.

Step 2 Select fibers of proper length according to actual requirements on site.

The contents of the temporary labels can be the same as the contents of the formal labels or can be decided on site.

Step 3 Attach temporary labels to distinguish the fibers.

Step 4 Coat the fibers using PVC corrugated tubes.

Place the fibers on a slope and then coat the fibers with PVC corrugated tubes. Do not cut corrugated tubes at random because exposed fibers may be damaged. If cutting corrugated tubes is required, cover the cut with insulation tapes to protect the fibers from

being damaged by sharp objects.

Step 5 Lay the fibers outside the cabinet. For details, see section 7.5.2 "Installation Principles."

Step 6 Lead the fibers from the waterproof module into the cabinet, and route the fibers near to the optical transmission equipment in the cabinet.

Step 7 Align the LC connector with the optical transmission device on the top of the cabinet and insert the connector until you hear a click sound.

Step 8 Use insulation tapes to seal the ports at both sides of the PVC corrugated tube.

Step 9 Attach the corresponding labels to both sides of the fibers, ensuring that the attaching points are 20–50 mm away from the port.

----End

7.5.4 Connecting the Fibers to the Transmission Interface Box Figure 7-22 shows the connections between the fibers and the transmission interface box.
