Voltage

1X Maximum Power

Consumption (W)

The grounding regulations and resistance requirements (including the lightning

protection requirements) are as follows:

DO Maximum Power

Consumption (W)

The communication equipment should be well grounded for reliable operation. Good

grounding ensures lightning protection and interference resistance. The grounding

cables in the equipment room should be routed in a radiating or flat way. Three

independent grounding cables should be used: The protection ground of the DC power

distribution system, the work ground of the power system and the lightning protection

ground.

The equipment adopts joint grounding with the grounding resistance less than 1 Ω.

Generally, the grounding resistance of BTSB should be less than 5 Ω. The engineering

requires the grounding resistance to be the smallest possible. The magnitude of

grounding resistance is affected by grounding post resistance, leading wire resistance,

contact resistance between the grounding post and soil as well as the soil type. The

greatest impact on grounding resistance comes from soil type. In areas with poor soil

conditions, some resistance-reducing agent (such as propenamide) may be added

around the grounding stake to meet the requirements. Changes in temperature will also

cause variations in resistance. In cold areas, the impact of temperature on the resistance

2-5

ZXC10 BTSB (V1.0) cdma2000 Base Transceiver Station Installation Manual

may be reduced by burying the stake deeply into the ground. Grounding stakes are

usually made of galvanized materials in proper size. The connection cables from the

grounding stake to the equipment should adopt copper-sheathed wires of good

conductivity (core wire section area less than 50 mm

, and length as short as possible).

If necessary, anti-erosion protection can be provided to the grounding connection parts

to guarantee low-resistance connection.

The working ground refers to the loop formed through the earth to transmit energy and

information. For instance, the 3-phase AC power supply neutral line ground and the

positive battery ground are both working grounds. This grounding approach can resist

electromagnetic interference and cross talk.

The protection ground refers to the grounding of the metal shell of the power supply

equipment to prevent hazards to human body due to power leakage.

In addition, the ground for lightning protection should be used to prevent lightning

stroke from damaging the equipment and to protect the safety of lives and properties.

2.1.5 Checking the Outdoor Installation Environment for the Antenna Feeder System

1. Check whether the height and size of the feeder window comply with the

requirements of the BTSB equipment and the engineering design drawing.

2. Check whether the height, weight bearing and grounding of the outdoor cabling

rack comply with the engineering design.

3. Check whether the height, weight bearing and grounding of the indoor cabling

rack comply with the engineering design.

4. Check the height, diameter, weight bearing, wind resistance, grounding,

lightning protection and position of the antenna pole of the BTSB on the roof to

make sure they comply with the BTSB equipment requirements and the

engineering design drawing.

5. Check the height, diameter, weight bearing, wind resistance, grounding,

lightning protection and position of the antenna pole of the BTSB on the iron

tower to make sure they comply with the BTSB equipment requirements and the

engineering design drawing.

2-6

Chapter Error! Style not defined.

2.1.6 Checking the Safety Conditions

Appropriate fire-fighting devices should be equipped in the equipment room, such as a

certain quantity of portable powder fire-extinguishers. As for a large equipment room, a

complete set of automatic fire-fighting system should be equipped. No inflammable or

explosive articles should be placed in the equipment room.

1. Storage of flammable and explosive materials in the equipment room is strictly

prohibited and necessary firefighting equipment must be installed.

2. Different outlets in the equipment room shall bear noticeable marks, and

dynamic electricity and lighting electricity should be noticeably differentiated.

3. The equipment room should be far from high-voltage power lines, strong

magnetic fields, strong electric sparks, or other factors that may threaten the

security of the equipment room.

4. Reserved holes in the floors should be covered with safety cover plates.

5. Proper lightning protection facilities should be in place before the power lines

and transmission lines are led into the equipment room.

Error! Style not defined.

2.1.7 Checking Other Auxiliary Equipment

Check the following items against the configuration requirements specified in the

backplane is to be replaced, the power cables need to be connected on site.

1. Connection between the DC distribution cabinet and the DC distribution panel

The PE grounding bar of the DC distribution cabinet must be reliably connected

to the protective grounding bar provided by the carrier through the yellow/green

wire with the copper core, plastic insulation layer and the same diameter as the

power cable.

The two -48V terminal blocks of the DC distribution cabinet should be reliably

connected to the -48V DC negative busbars of the active/standby DC

distribution panels respectively. The GND terminal blocks of the DC distribution

cabinet should be reliably connected to the -48V DC positive busbars of the

active/standby DC distribution panels respectively.

If there is no DC distribution cabinet, PE wiring terminals of the cabinets must

be reliably connected with the protective terminal blocks provided by the carrier.

The power cables led out from -48 V and GND wiring terminals of each cabinet

are directly connected to the -48V DC negative busbar and -48V DC positive

busbar of the DC distribution panel.

2. Connection between the DC distribution cabinet and the cabinet

connected to the PE wiring terminal on the P power supply of the cabinet, and

the other end to the PE busbar of the DC distribution cabinet.

3. Intra-module cabinet cascading

In the same module, the GND wiring terminals of each cabinet should be

connected with each other via a shorted cable.

4. Precautions for connecting power cables

While fixing the lug at one end of the DC distribution frame, add the flat washer

and spring washer to make sure that the lug is reliably fixed and that the cable

and wiring bar are in good contact to minimize the contact resistance. For details,

When installing lugs, if two or more cables need to be installed on one wiring

post, the lugs should be crossed or installed in a back-to-back way, instead of

being overlapped. If they must be overlapped, they should be bent into 45

before installation. Note that the big lug should be put under the small one.

It is recommended to adopt this method in all the places where the lugs need to

be installed. For details, see Fig. 5.3-5.

z Overview of BTSB grounding system installation

z Installation procedure of the BTSB grounding system

6.1 Grounding System Overview

This section describes the grounding of the BTSB equipment and the installation of the

grounding device accessories required for the BTSB installation. It covers the

installation of the grounding copper bar, the feeder grounding clip and the lightning

arrester.

The purpose of grounding is to ensure the safety of human body and equipment and to

improve the capability of the equipment to resist electromagnetic interference.

The grounding system consists of indoor part, outdoor part and underground ground

grid of the building.

As to the engineering, the user is responsible for the basic ground grid construction of

the grounding system, the grounding engineering of the iron tower and the building,

and the provision of the connecting point for the indoor and the outdoor grounding

copper bars to connect the ground grid via separate 50 mm2 wires, as shown in Fig.

6.1-1.

The wire of the indoor rack protection ground (PGND) is connected to the indoor

grounding copper bar.

The wire of the BTSB rack working ground (–48VGND) is connected to the working

ground terminal of the BTSB DC power rack.

To ground the lightning arrester, connect it to the outdoor grounding copper bar with a

wire. To ground the feeder, connect each feeder to the outdoor grounding copper bar

through a grounding clip before it enters the equipment room. This is shown in Fig.

6.1-1.

6.2 Installing the Grounding System

6.2.1 Installing the Outdoor Grounding Copper Bar

The outdoor grounding copper bar is used for lightning protection grounding. It is

usually installed on the wall outside the feeder window. The best place for it is right

under the feeder window or on the rainproof wall of the feeder well on the roof top. In

principle, it is better to put it close to the feeder window.

During the practical installation, first determine the installation position of the

grounding copper bar by following the engineering design drawing, and then install the

grounding copper bar on the wall with the expansion bolts. See Fig. 6.2-1 for the

structure of the grounding copper bar.

Style not defined.

Fig. 6.2-1 Appearance of the Grounding Copper Bar

6.2.2 Installing the Feeder Grounding Clip

Caution:

No installation of grounding clip shall be performed in case of any lightning stroke, lest

bodily injury may be incurred.

When installing the grounding clip, keep the feeder at the joint of the grounding clip

and the feeder straight.

6-3

ZXC10 BTSB (V1.0) cdma2000 Base Transceiver Station Installation Manual

6.2.2.1 Grounding Principles of the Main Feeders

1. Usually, each main feeder should be grounded with grounding clips at least at

three positions: on the tower platform, at the place where the main feeder leaves

the tower for the outdoor cabling rack, and before the cable enters the equipment

room. When the main feeder is over 60m, grounding clips should be added in

the middle of it. Generally, a grounding clip is installed every 20m on the feeder.

2. The antenna feeder system, antenna support and new cabling rack installed on

the roof top should be welded to the lightning protection grid of the building.

The feeder should also be grounded at three positions: where it leaves the

antenna pole, where it leaves the roof top, and where it enters the equipment

room.

3. When the main feeder enters the equipment room from the roof top along the

wall, the outdoor cabling ladder provided by the network operator must be

grounded. If not, urge the network operator to finish it as soon as possible.

6.2.2.2 Installing the Grounding Clip

1. Prepare the tools: Paper cutter, flathead screwdrivers, wrench and sharp-nose

pliers.

2. Select a proper installation position for the grounding clip. Cut open the sheath

of the 7/8" feeder to the size of the grounding clip. The structure of the

grounding clip is shown in Fig. 6.2-2.

Chapter Error! Style not defined. Error!

Style not defined.

3. Lead the grounding cable of the feeder lightning grounding clip to the ground

grid. No reverse direction is allowed. The angle formed by the grounding cable

and the main feeder should not be more than 15

. No reverse folding is allowed.

In the case the antenna feeder system is installed on the tower, the grounding

cable of the grounding clip should be led downward along the tower body.

In the case the antenna feeder system is installed on the roof top, the grounding

cable of the grounding clip should be led close to the building lightning

protection grid.

4. Before installing the grounding clip, wrap the grounding cable at the grounding

clip end that is close to the grounding cable copper sheet with the waterproof

adhesive tape, as shown in Fig. 6.2-3. This can improve the sealing effect and

prevent the rain from falling into the feeder interior along the grounding cable.

Fig. 6.2-3 Wrapping the Grounding Cable of the Grounding Clip with Waterproof Tape

5. Clamp the feeder external conductor with the grounding cable copper sheet and

the locking spring plate, so that the grounding cable copper sheet and the feeder

external conductor are fully meshed.

6. Take the following steps to conduct the waterproof treatment to the joint of the

grounding clip and the feeder:

1) First wrap the waterproof adhesive tapes and then wrap the PVC tapes.

2) To wrap the waterproof adhesive tapes, apply them layer by layer from bottom

to top first, then from top to bottom once again, and finally from bottom to top

thrice, that is, wrap three layers of them. During the process, make sure the

upper layer overlaps the lower layer by about half the width of the tapes.

7. The grounding end of the grounding clip can be connected to the main tower

body or the outdoor cabling rack (connected to the lightning protection grid of

6-5

ZXC10 BTSB (V1.0) cdma2000 Base Transceiver Station Installation Manual

the building) on the roof top. Remove paint and oxide within the radius of about

13 mm at the connection place, and cover the clean area with antioxidant to

ensure good electric contact. When the grounding end is connected, paint

another coat of antirust paint.

8. Before the main feeder enters the room, the grounding end of the grounding clip

can be connected to the outdoor grounding bar.

6.2.3 Installing the Indoor Lightning Arrester

For the wide-band lightning arrester that need not be grounded separately, you may

directly connect it in serial to the place between the main feeder and the indoor cabinet

top jumper. During the installation, the lightning arrester and indoor equipment as the

cabling rack should be insulated.

For the lightning arrester that need be grounded, a lightning arrester frame should be

provided. Please refer to the assembly instructions provided by the supplier for the

assembling of the lightning arrester frame. The installation steps are as follows:

1. Install the lightning arrester on its frame in advance.

During the installation, please note that the connectors at both ends of the

lightning arrester are different: One end is a DIN male connector (DIN-M) and

the other is a DIN female connector (DIN-F). Make sure that the DIN-M

connector of all the lightning arresters installed on the frame are in the same

direction, and the DIN-F connector of all the lightning arresters are in the same

direction. The lightning arrester should be securely installed on the frame and in

close contact with the frame.

2. Fix the assembled lightning arrester to the cabling rack.

Plan the installation position carefully to make both the main feeder and the

cabinet top jumper easily be connected to the lightning arrester and to enable

easy cabling.

The lower part of the lightning arrester frame that is secured to the cabling rack

can be adjusted according to the width of the cabling rack.

When the lightning arrester frame is installed on the cabling rack, make sure that

its DIN-M connector points to the main feeder and its DIN-F connector points to

the connection line from the jumper to the rack.

3. The lightning arrester is installed indoor. Its grounding cable should be

connected to the outdoor grounding copper bar and should not contact with the

conductor of the indoor cabling rack. The lightning arrester frame is insulated

from the cabling rack.

The installation of the lightning arrester frame is shown in Fig. 6.2-4.

5. Generally the internal cables have been installed before delivery, so you only

need to check their status after the cabinet installation. Check whether the cables

are properly connected, whether the socket connectors are firmly and properly

inserted, and whether the distributed cables are in good order and without

shortages. If any socket connector is damaged or loosened or any cable is

scratched, try to repair it or re-distribute the cable.

7.2 Installing Cables in the BDS Cabinet

Chapter Error! Style not defined.

They are usually used to connect a remote RF cabinet.

The optical fiber jumpers connect the blind match connectors of the BDS backplane

RIM0 master/slave slots to the optical adaptors on the two BIM6 interface boards. The

jumpers are available with the following types: MTP4-LC-0.5M, BMTP8-LC-0.5M

and BMTP12-LC-0.5M, and the optical fibers are connected in the spectrum order of

blue, orange, green, brown, gray, white, red, black, yellow, purple, pink and cyan.

When installing optical fibers, make sure that the bending radius is larger than 40 mm

to prevent any damages. In addition, the optical fibers should not be bundled too tight

and there should be some space kept between an optical fiber and the clips.

7.2.4 Installing Monitoring Cables in the BDS

The internal monitoring cables of the BDS include cables for front access control

monitoring, CCM board temperature monitoring, CHM board temperature monitoring,

flooding monitoring and fan monitoring.

The internal monitoring cables adopt the one-to-eight structure with the ends being A

and B1 ~ B8. End A is connected to the X154EMSOCKET socket on the BDS

backplane; B1 is connected to the front door position switch along the right side of the

chassis; B2 is designed to be connected to the back door position switch (now idle); B3,

B4 and B5 are temperature sensors connected to the top of the CCM and CHM boards;

B6 is connected to the DB25 socket of the fan plug-in box backplane; B7 is to the

lightning-proof board of the BDS filter; B8 is to the flooding sensor (unnecessary when

the BDS is mounted on the RFS cabinet) at the lower right corner of the BDS.
