2 Toxic Articles

2.1 Beryllium Oxide

Warning:

Some equipment components carrying toxic beryllium oxide are chosen unavoidably.

Only when the components carrying beryllium oxide are damaged can the beryllium oxide do harm to human body. The personnel who contact or handle the components should be aware of the component peculiarity and take corresponding preventive measures beforehand.

There are many parts of the equipment use the component carrying beryllium oxide, such as power amplifier circuit, combiner circuit and so on. Components and modules should not placed in the environment that may cause mechanical damage, which consequently lead to the discharging of beryllium oxide.

The components carrying beryllium should not be discarded freely. To go along with the chemical treatment or special waste treatment for the component carrying beryllium oxide, one must follow the local regulation in this respect.

2.2 Hydrochloride

Warning:

Some equipment components carrying hydrochloride are chosen unavoidably. The burning of these components will generate toxic gas.


4

Preventive measures should be taken beforehand so that the components will not get burned, and even if the burning occurs, the toxic gas will not be inhaled into human body. The components should not be discarded freely. To dispose the component, the personnel should make the necessary chemical treatment or special waste processing for the component carrying hydrochloride in accordance with the related local regulation.

2.3 Hydrofluoride

Warning:

Some equipment components carrying hydrofluoride are chosen unavoidably. The burning of these components will generate toxic gas.

Preventive measures should be taken beforehand so that the components will not get burned, and even if the burning occurs, the toxic gas will not be inhaled into human body. The components should not be discarded freely. To dispose the component, the personnel should make the necessary chemical treatment or special waste processing for the component carrying hydrofluoride in accordance with the related local regulation.

3 Electrical Safety

3.1 High Voltage

Danger:

High voltage power supply provides electricity for equipment operation. Direct contact or indirect contact via damp objects with high-voltage wires or mains supply may be fatal.

Installation of AC power supply equipment must be implemented in compliance with local safety regulation, and the personnel engaged in AC power supply must be qualified in high-voltage and AC operations.

Electrical conductors such as watch, bracelets and ring must be removed before operation.

If the cabinet is found to be wet, please immediately switch off power supply. Keep the equipment dry in humid environment.


5

Warning:

Improper high-voltage operations may result in fire and electric shocks. Therefore, AC cable must be laid in compliance with local codes. High-voltage operators should be trained and be qualified.

3.2 Power Cable

Caution:

Live installation and removal of power cable are definitely prohibited. Electric spark or arc may result from contact of power cable with conductors, causing fires or eye injury.

Power must be switched off before installation and removal of power cable. Before connecting cable, make sure that the cable and cable tag to be used

should match actual installations.

3.3 Tools

Warning:

High-voltage and AC operations call for special tools instead of general-purpose or makeshift tools.

3.4 Drilling Holes

Warning:

Unauthorized drilling on the cabinets is strictly prohibited. Improper drilling may damage the connections and cables inside the cabinet, and the metal filings resulting from the drilling may cause short-circuit of circuit board if the fillings fall into the cabinet.

To drill on the cabinet, insulated gloves must be worn and the cables inside the cabinet must be removed.

The installation personnel should protect their eyes properly when drilling. Flying metal filings may hurt one’s eyes.


6

Prevent metal filings from falling into the cabinet. Improper drilling will deteriorate the electromagnetic shielding performance of the

cabinet. After drilling, remove all the metal filings immediately.

3.5 Thunderstorm

Danger:

High-voltage and AC operations and operations on steel towers and masts are strictly prohibited in thunderstorms.

Thunderstorms can generate powerful electromagnetic field in the atmosphere. Therefore, equipment should be grounded properly in order to prevent the equipment from being thunderstruck.

3.6 Electrostatic

Caution:

Static electricity generated on human body may damage the electrostatic-sensitive parts on the circuit board, such as large-scale integrated circuit (IC).

In dry climate, the electrostatic charge carried by human body may be up to 30 kV, which will remain on the human body for a rather long period of time. The operator’s contact with the component and the electric discharge will cause damage to the component.

Before contacting any equipment, hand-held plug-in boards, circuit boards and IC chips, put on anti-static wrist belts with one end well grounded so as to prevent sensitive parts from being damaged by static electricity on the human body.

Before operators touch the board or module, they should discharge the electrostatic in their body. That is, before the operator touch a board or a module, he must wear anti-static wrist strap. The connecting line between wrist and grounding point should connect in series with a resistance greater than 1M to protect people from being accidentally shocked. The resistance value greater than 1M is rather low in terms of electrostatic voltage discharging. The anti-static wrist strap should be checked regularly. It is strictly prohibited using other cable to replace the cable of anti-static wrist strap.


7

Electrostatic-sensitive board or module should not be in contact with the object with electrostatic or the object that may easily generate electrostatic.

Electrostatic-sensitive board or module can only contact the quality discharging material, such as the anti-static packing bag. The board in stock or in the course of transportation should be packaged with anti-static packing bag.

Before the measurement device is connected to boards or modules, it should firstly discharge its electrostatic; that is, the measurement device should be grounded in the first place.

The boards or modules should not be placed near strong DC magnetic field, say, near the cathode ray tube of the scope. The safety distance should be outside of 10 cm range at least.

The damage caused by electrostatic is accumulative in effect. If the damage is slight, the component will not malfunction. However, as the time of damage increases, the components may suddenly fail. The electrostatic discharging damage on the component is of two types: explicit damage and implicit damage. Implicit damage is not shown when the damage occurs, whereas the component may become vulnerable and easily get damaged under the condition of over-voltage and of high-temperature.

The correct way of wearing anti-static wrist strap is shown in Figure 1.

Plug of anti-static wrist strap

Figure 1 Diagram of wearing anti-static wrist strap

3.7 Label Stickers of Power Supply Cables

Attention:

Before connecting the cables, check the correctness of label stickers and then make the connection.


8

3.8 Leakage Current

Warning:

To avoid the occurrence of large leakage current, the equipment must be grounded before it is connected with power supply.

Before connecting the AC input power supply, the operation and maintenance personnel should first connect the protection-grounding terminal of the equipment housing with the earth. The purpose of doing this is to avoid the electric shock on human body result from leakage current, which is usually caused by the EMI wave filter earth capacitance of the equipment AC power supply input terminal or the Y capacitance of the primary power supply.

3.9 Environment with Flammable Air

Danger:

The equipment should not be placed in the environment where flammable, explosive air or smog exists. No operation of any kind can be performed in this environment.

The operation of any digital equipment in this equipment poses absolute threat in this environment.

4 Batteries

4.1 General Operation

Danger:

Before undertaking the battery operations, the personnel should carefully read the safety precautions for handling batteries and the connection of batteries.

Improper operation of batteries will be dangerous. Guard against short-circuits of batteries or electrolyte spillover in operation, which may pose a potential threat to


9

equipment, corrode metal articles and circuit boards, damage equipment and result in short circuit of circuit board.

Before undertaking the installation and maintenance of batteries, the personnel should take the following measures to ensure safety:

The batteries should be handled with care. Avoid strenuous vibration during the move.

Metal articles such as watch, bracelets and ring must be removed. Use special insulated tools. Wear eye protection gears and take preventive measures. Wear rubber gloves and apron in case of electrolyte spillover. Hold the positive pole of batteries upright during handling. Do not handle them

upside down or in slant position.

4.2 Short Circuit

Caution:

Short-circuit will cause personal injury. Although the voltage of ordinary battery is not high, the powerful instantaneous current generated by short-circuit may release immense energy.

Prevent short-circuit of batteries caused by metal articles, such as short-circuit caused by improper use of tools. If permitted, first disconnect the batteries at work and then proceed with other operations.

4.3 Harmful Gases

Caution:

Unsealed lead acid batteries should not be used, as the gas released from the batteries may cause fires or equipment corrosion. Batteries should be placed horizontally.

Batteries may give off inflammable gases in operation, so the place where the batteries are located should be well ventilated and fire prevention measures should be taken.


10

4.4 High Temperature

Caution:

Excessively high temperature of batteries will cause deformation and damage of batteries and spillover of acid liquid.

When the temperature of battery is over 60°C, check whether there is spillover of acid liquid.

In case of acid liquid spillover, please handle the acid spillover in time.

4.5 Acid Liquid

Caution:

In case of acid liquid spillover, make sure that such spillovers are absorbed and neutralized.

To move leaking batteries, mind the damages liable from the acid liquid. Once acid liquid is found to have spilt over, absorb and neutralize it with the following materials.

Bicarbonate: NaHCO3 Barilla: Na2CO3 Soda: Na2CO310H2O Consult with battery manufacturers as regards materials used to absorb and

neutralize acid liquid.

4.6 Battery Replacement

Warning:

Operation and maintenance personnel should not replace the batteries of prescriptive model with that of different model; otherwise, the explosion danger of the batteries may incur.

To prevent battery leakage due to aging, periodical checking (at least once half a year) is needed.

5 Microwave and Magnetic Field

5.1 Introduction

The equipment antenna in service will generate electromagnetic radiation. Standing too close to the antenna is against the safety codes. The equipment can only be installed and maintained by trained professional personnel. The radiation design of the equipment should meet the IEEE C95.1-1991 recommendation. When working near the full-power transmitting antenna, one should read the following safety working requirement.

5.2 Definition of the Environment

The uppermost level limit of the environment that can be exposed to radio magnetic radiation is of two kinds: one is "controlled environment" and the other is "uncontrolled environment" with less radiation.

Controlled environment

"Controlled environment" refers to a certain location where the personnel who enter the area are aware of the potential threat of exposing themselves in the radio frequency radiation environment. The magnetic field level of the area is higher than that the level of "uncontrolled environment" but no greater than that of "controlled environment level" listed in the table.

Uncontrolled environment

"Uncontrolled environment" refers to a certain location where the personnel who enter the area are not aware of the potential threat of exposing oneself in the radio frequency radiation environment, and they cannot be in control of the environment where they are situated. This location may include living environment or working environment. The magnetic field level of the location cannot be greater than the uppermost level that can be exposed in the "uncontrolled environment".

5.3 Minimal Distance Formula

The following content introduces how to calculate the minimal safety distance. The formula is used for calculating the minimal safety distance apart from all types of antenna.

rmin=N10 10

G-L（（

P4 W

OUT

The respective element in the formula is explained in the following:


12

Rmin is the minimal safety distance, and its unit is meter.

N is the number of frequency carriers.

Pout is the output power of the frequency carrier, and its unit is W.

L is the loss from transmitting party to the receiving party, and its unit is dBm.

G is the antenna gain, and its unit is dBm.

W is the greatest field power density permitted, and its unit is W/m2.

In the uncontrolled environment, the greatest field power density permitted is f/150, in which f is the frequency, whose unit is MHz. Its tested value is the mean value measured when the testing time is over 30 minutes. In the controlled environment, the greatest filed power density permitted is f/30, and its tested value is the mean value measured when the testing time is over 6 minutes.

Upon the above formula, the minimal safety distance on the axial line of the antenna field is shown in Table 2.

4.4 Unpacking Equipments

In the non-turnkey project, both the customer and the project supervisor (engineer from Huawei or cooperative party) are required to be present at the unpacking site. If one party is absent at the unpacking site, another party who unpacks shall responsible for any errors occurring to the articles.

In the turnkey project, it is the project supervisor and the order management engineer who unpacks, checks & accepts, hands over the articles, and makes a confirmation with signatures. The operation of Unpacking check and problem feed back in this case is almost the same as that of the non-turn key project, except that the customer does not need to sign. The goods will be handed over to the customer after passing the initial check of the project.

The following will mainly deals with the former case.

4.4.1 Collate Packing List

Before unpacking, both parties should check if the packing cases are damaged. If so, stop unpacking and contact the order management engineer at the local office of Huawei, waiting for the handling. Meanwhile, check if the quantity of cases on the site agrees with the “Packing List”, and if the place of delivery agrees with the actual installation place. If there is any disagreement, the project supervisor should feed back the Article Problem Feedback Form confirmed by the customer with a signature to the order management engineer at the local office within 3 days.

After all the above inspections are ok, unpack the cases to check and accept the articles.

There are two kinds of packages: wooden cases and cartons. The unpacking tools should be used accordingly.

Note:

The Packing List is usually in the carton with red label.

4.4.2 Unpacking Inspection on Cartons

Generally, the carton is used to pack various boards, modules and terminal equipment, etc. The board is placed in a plastic bag for transportation. Antistatic


4-5

measures should be taken during the unpacking so as to avoid any damage to the equipment.

Before opening the carton, first check the label on it to have an idea of the type and number of the modules in it. And then use a paper knife to cut open the tapes along the seams of the cover, and take out the module. The unpacking operation of NMCU is illustrated in Figure 4-1. The unpacking of NDRU and NPSU are the same with NMCU.

(1) Cushioning Top Pad (2) NMCU (3) Cushioning Bottom Pad (4) Carton (5) Moistureproof Plastic Bag (6) ESD Plastic Bag

Figure 4-1 Unpack carton of NMCU

Caution:

When the board box is open, the board shall be seen wrapped in a packing bag and an antistatic bag. Do not tear or discard these two bags, as they can be used to store the spare boards or to wrap the failure boards for repair.

Check the goods after unpacking. The next unpacking cannot be done unless the present unpacking check has been finished. The check covers:


4-6

Whether the internal packing has been damaged; Whether the number and type of the boards and modules are in line with the

Packing List; Whether there is any broken printed circuit boards or any components detached

from the board; Whether the display, keyboard and mouse are all there and whether there is any

damage on them.

For inner packing, any breakage of the inner packaging should be recorded in detail.

B.2.3 Printing Labels

Note:

The contents on the metal label have been printed before delivery, so there is no need to fill it out during installation.

The contents can be printed or written on the labels. Printing is recommended for the sake of high efficiency and eye-pleasant layout.

I. Template for the printing

The Word-form template is available for label printout. You can download the template from http://tech-support.huawei.com/asp/comm/index.asp (path: //support/technical document/project management/installation and maintenance/document/others), or get the template from Huawei local office.

When using the template, you can directly modify the contents on the template, and the following should be observed:

The settings of centered characters, direction, and fonts should not be changed. When there are too many characters to be filled in, zoom out the characters, but

make sure the printouts are clear and legible.

II. Cells merging on the template

To merge the cells, you should first recover the table structure (if gridlines are displayed, you can start from Step 3 directly).

1) Select the menu item [Edit/Select All]. 2) Select the menu item [Format/Borders and Shading/Borders]. Select Box and

click <OK>. 3) Drag the mouse to select the cells to be merged and select the menu item

[Table/Merge Cells].

If two merged cells are still not enough to accommodate the characters, use multiple lines.

III. Requirements on the printer

To print the labels, laser jet printer must be used, although there is no restriction on the model of the printer. Before printing the label, set up the page and try the printing on ordinary blank paper (both sides are blank):

1) Cover the blank paper onto the whole page of label paper, and check whether the page setup conforms to the requirement.


B-5

2) Make sure the printer properties, such as "paper size" and “direction”, have been set correctly.

3) If the warning prompt as shown in Figure B-5 appears before printing, click <Ignore> to continue the printing.

Figure B-5 Warning prompt before printing

If the printout confoms to the requiremnt, print it to label paper. If the printout does not conform, adjust the page setup and try the printing again, until the correct printout is produced. The method of adjusting the page setup is as follows:

1) Select the menu item [File/Page Setup]. 2) Select the Margins tab page. 3) Select Left for Gutter Position. 4) Set Header and Footer as 0, and adjust the values of Top, Bottom, Left, and

Right.

After the page setup has been made correct, save it for future use. This page setup is only necessary in the first time you use the template to print the labels.

IV. Requirements on feeding the printer

Different from the ordinary paper, the label paper is composed of two pages. No matter what model of printer you are using, feed in the labels one after another by hand. Never use the auto-feed mode in order to avoid jamming the labels. Different models of printers may have different feeding modes, make sure to feed in the labels correctly.

V. Requirements on the printed label

Make sure the printed label satisfy the following requirements:

All the printouts must be on the label, and nothing should be printed on the bottom page of the label.

Contents in the cells should be aligned in the center. In a single-line printout, the dividing lines and the mark “TO” should not be covered by the printed characters.

When the cells are merged and the printouts are made in multiple lines, avoid covering the mark “TO” when printing the texts by using the space bar to move the printing contents to the next line.


B-6

VI. Writing Labels

Use the black oiliness markers delivered together with the device to write the labels.

In special cases, black ball-pens are allowed, although not recommended. When writing with the ball-pen, take care not to leave the oil on the label, which may contaminate the label and blur the words..

Note:

The delivered marker has two nibs. Make sure to use the smaller nib to write the labels.

For the sake of easy recognition and good looking, the font in handwriting should be close to the standard typeface as much as possible. Table B-1 shows the standard typeface.

Appendix C Assembly Specifications of Communication Cables

C-1


C.1 About This Appendix

This appendix describes the assembly procedure of communication cables, including:

Cable Assembly by Using RJ45 Connectors Cable Assembly by Using SMB Connectors

C.2 Cable Assembly by Using RJ45 Connectors

C.2.1 Parts Required

RJ45 connectors, network cables.

C.2.2 Stripping and Cutting

Strip the cables according to the cable structure and sizes as indicated in Figure C-1 and Figure C-2. Cables assembled by using RJ45 connectors are of two types, namely, round communication cable and flat communication cable, which are shown below in Figure C-1 and Figure C-2 respectively. The length of the stripped segment on either cable is “L+ (2~3mm)”. The meaning of “L” is shown in Figure C-4 while “2~3mm” is the length reserved for wire cutting and flushing.

Figure C-1 Outline of a round communication cable

Figure C-2 Outline of a flat communication cable



C-2

Caution:

When the round communication cable and the flat telephone line are stripped, make sure that the end of the sheath should be neatly stripped and the cutting angle should be vertical to the cable.

Do not damage the shielding layer around a shielded cable when stripping the cable sheath. After the stripping, fold the shielding layer back to the root of the cable sheath as shown in Figure C-3.

The core wires should be cut neatly, especially for the round communication cable. Spread the core wires evenly apart and cut them neatly with the cutting tool, as shown in Figure C-4.

The length of the truncated cable should be in accordance with the requirements shown in Figure C-4, that is, either the round communication cable or the flat telephone core wire should be “L” in length.

(1) A folded shielding layer

Figure C-4 Outline of neatly-cut core wires

C.2.3 Wire Insertion and Assembly

1) Insert the 8-core flat telephone line from the end of the RJ45 connector until the connector butts against the external protection layer of the cable. Each core wire should be inserted along the trough of the RJ45 connector to the end of the connector, so that the core wires and the RJ45 connector end are flush, as shown in Figure C-5.



C-3

2) Round communication cables should be inserted into the connector in the same way mentioned above. The core wire end should be flush so that it is easy to be put in position.

3) Wires in a shielded cable should also be inserted into the connector in the same way, with the folded shielding layer contacting the built-in shielding piece at the tail of the RJ45 connector and butting against point A of the connector. See Figure C-5.

C-4

C.2.4 Crimping

After the cable is assembled, crimp the connector using the RJ45 crimping pliers into a finished product as shown in Figure C-6.

Figure C-6 A crimped RJ45 connector

Caution:

During the crimping, place the RJ45 connector in the proper trough of the crimping pliers and crimp it as required.

Make sure that the connector is fully crimped. After the crimping, the metal blade should be lower than the top surface of the RJ45 connector.

When crimping a RJ45 connector onto a shielded cable, make sure that metal cutters in the connector are crimped in position and that the built-in shielding piece of the connector securely contacts the shielding layer of the cable.

C.2.5 Checks

1) Outer appearance inspection

Any cable with visible defects such as breakage or crack to the connector shell or to the lock piece or cable out of position, etc. is a reject.

2) Wire order check

Any cable whose wire crimping order does not satisfy the design requirements is a reject.

3) Continuity check

The continuity ratio should be 100% and the wires should not be short-circuited. Otherwise, the cable is a reject.



C-5

Caution:

As to the shielded cable assembled with the shielded RJ45 connectors, check the continuity between the shielding shell of the connector and the shielding layer of the cable. Any cable without such a continuity is a reject.

C.3 Cable Assembly by Using SMB Connectors

Following is the most commonly used method to assemble an SMB connector.

C.3.1 Mounting the Heat-Shrinkable Tube and Crimping Sleeve

See Figure C-7.

Figure C-7 Mounting the heat-shrinkable tube and crimping sleeve

C.3.2 Stripping

Use a cable stripper to strip the cable sheath and inner insulating layer without any damage to the shielding layer and internal conductor. The end faces of the cable sheath and inner insulating layer should be flush and smooth. The specific stripping dimensions (in mm) are shown below in Figure C-8.

C.3.3 Soldering Pins

Use the soldering tin with melting point above +125°C to weld the pins with the conductor inside the cable.

In the process of welding, insert the cable conductor into the small central hole at the tail of the pin until the step at the pin tail contact the inner insulating layer of the cable, as shown in Figure C-9.

(1) Inner insulating layer (2) Boss

Figure C-9 Soldering Pins

Caution:

In the process of welding, do not scald the cable inner insulating layer. In the process of welding, try not to let the soldering tin flow out to the exterior face of the pin. In the

case of outflow, they must be cleaned off lest they should affect next process.

C.3.4 Crimping External Conductor

Insert the knurled cylinder of the SMB connector between the inner insulating layer of the cable and the shielding layer so that the shielding layer evenly adheres to the knurled cylinder of the connector. Meanwhile, prop the boss of the pin against the inner insulating core of the connector, as shown in Figure C-10.



C-7

Figure C-10 Crimping an SMB connector onto a coaxial cable

Push the crimping sleeve so that it fully covers the shielding wires, then perform crimping using the SMB crimping pliers.

Caution:

Before crimping, check the SMB connector prior to the pre-crimping. Any shielding wires exposed outside the crimping sleeve should be in time curtailed using the scissors before crimping is allowed.

During the crimping, the SMB connector should be properly placed so that it meshes with the crimping mold in the crimping pliers.

C.3.5 Blowing Heat-Shrinkable Tube

Place the heat-shrinkable tubing onto the joint of the crimping sleeve and the cable, evenly blow in hot air by using the hot air gun until the heat-shrinkable tubing evenly shrinks. Refer to Figure C-11 below.

(1) Blow-shrinking

Figure C-11 Blowing the heat-shrinkable tube to shrink It

C.3.6 Checks

Continuity check. Use a multimeter to measure the continuity between the connector pin and the inner conductor of the coaxial cable and that between the outer shell of the connector and the shielding layer of the coaxial cable.

Insulation Test. Use a multimeter to measure if short circuit exists between the inner and external conductors.

Tensile strength test. Pull outward the inner pin with proper force (about 60 N) and there should be no visible displacement of the inner pin.

Outer appearance inspection. Check if there is any shielding wire exposed outside or if the pin is not inserted in position, etc.

D.3 Assembly Procedure Description

D.3.1 Cutting the cable

1) Place and roll the cable coils on the support. Measure and cut off a segment of the cable according to the cable layout plan of the project design, as shown in Figure D-2.


D-3

(1)

(1)

(1) Rolling direction

Figure D-2 Cable assembling

2) Cut the cable with a handsaw. Since there are many core wires in the cable and they are relatively thin and soft, the serrulate sawblade (0.8mm teeth spacing) is recommended for the cutting. The cable should be cut, if possible, using a KT35 wire clipper.

D.3.2 Mounting the heat-shrinkable tube

Mount the heat-shrinkable tubing onto the cable from the cable end as required in the cable design.

D.3.3 Stripping

Generally special stripping tools or electrical knives are recommended. The AM35 wire stripper is recommended for round cables if available because it is simple to use.

1) The stripped length is related to the length of the crimping tubing behind the bare terminal. For the JG bare terminal commonly used by Huawei, the relation should comply with the formula: L1=L2+(2~3mm), in which L1 is the stripped length and L2 is the length of the effective crimping area of the JG terminal, as shown in Figure D-3.

2) Remove the insulation layer from the multiple core wires at the end, and strand them tightly. The stranding direction should be the same as the original merging direction of the core wires.


D-4

(1) (1) Crimping sleeve

Figure D-3 Cable stripping

Caution:

When stripping, check with care whether the cable core wires have been seriously oxidized or corroded. If such problems exist, cut off the damaged segment until the cable is free from oxidization or corrosion.

D.3.4 Crimping

1) Crimp the cable with special crimping pliers or special molds. 2) Try to insert the core wires into the wire inlets of the terminal crimping tubing

until they cannot be pushed any further. After this is done, the core wires should protrude out 2~3mm longer than the terminal, as shown in Figure D-4.

3) Before crimping the wiring terminal, place the cable in the connection position so that the contact surface of the wiring terminal is parallel to the bus bar of the power supply. If they are not parallel, hold the end of the terminal using the pliers to adjust it until parallel.

4) During crimping, use the mold of the corresponding cross section. The corresponding molds of the 4 types of power cables are shown in Figure D-5.

5) To ensure the reliability of electrical connection, the crimping position should be as shown in Figure D-6.

Caution:

The heat-shrinkable tubing on the cable should wrap up the whole crimping sheath of the bare terminal including the joint between the terminal and the cable.


D-7

D.3.6 Checks

1) Tensile strength sampling test

The finished product of 50mm2 cables should have a tensile strength of 1KN, 95mm2 cables should have 2KN, 120mm2 cables should have 2.5KN and 240mm2 cables should have 5KN.

2) Outer appearance inspection

The product with an oxidized terminal surface and damaged cable sheath is substandard.

D.3.7 Labeling

Attach corresponding labels to both ends of the power cable 20mm away from the cable ends.

Appendix E Waterproof Treatment for Outdoor Connectors

E-1


E.1 About This Appendix

This appendix describes the water treatment procedure, including:

Introduction to Waterproof Tape Waterproof Treatment Procedure

E.2 Introduction to Waterproof Tape

There are two types of waterproof tape needed: PVC tape and waterproof insulation tape, as shown in Figure E-1.

(1) (2)

(1) PVC tape (2) waterproof insulation tape

Figure E-1 PVC tape and waterproof insulation tape

E.3 Waterproof Treatment Procedure

Below is the procedure of waterproof and encapsulation treatment:

1) Clean the connectors. 2) Stick the end of the waterproof insulation tape to the cable at the point 2~5cm

from the connector. 3) Stretch the tape until it is 3/4~1/2 as wide as its original shape. Make sure that the

stretched width is at least 1/2 of the original width, otherwise over-stretching may damage the molecular structure of the tape and lower its reliability).

4) Wrap up the cable spirally upward while maintaining this stretching strength. Make sure that the overlapping area of adjacent tape layers is 1/2 of the stretched width, as shown in Figure E-2.



E-2

Caution:

Make sure that the stretched width is at least 1/2 of the original width, otherwise over-stretching may damage the molecular structure of the tape and lower its reliability

Figure E-2 Wrapping up the connector with waterproof insulation tape

5) When wrapping to the point 2~5cm another connector or grounding clamp, reverse the direction to let the wrapping goes back towards starting point. When it reaches the starting point, reverse the direction one more time. In this way, the connector is wrapped up with three layers of waterproof insulation tape.

6) After wrapping, squeeze the tape stuck to the connector to make sure no air remains between tape layers.

7) When the wrapping of the waterproof insulation tape is done, it is necessary to wrap it up with PVC tape to prevent the wearing and aging of the waterproof insulation tape.

8) The wrapping of PVC tape is similar to that of waterproof insulation tape. Start wrapping spirally upward with 1/2 width of overlapping between adjacent layers. Reserve the wrapping direction twice to make three-layer cover. Make sure to maintain the stretching strength.
