Safety SpecificationsElectrical Safety

Electric Shock:

Never install or uninstall power cables while they are live becausewhen touched with a conductor may produce sparks, resulting infire or damage to eyes.

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

Before connecting a cable, make sure that the cable and its labelmeet the actual installation requirements.

Warning:

It is not allowed to drill cabinet holes without permission. Unqual-ified drilling could damage wiring inside the cabinet. Additionally,the metal pieces inside the cabinet created by drilling could resultin a shorted circuit board.

Antistatic

Electrostatic:

Static electricity produced by human body can damage static-sen-sitive components on circuit board, such as large-scale integratedcircuits.

Friction caused by human body activities is the root cause of elec-trostatic charge accumulation. Static voltage carried by a humanbody in a dry environment can be up to 30 kV, and can remain inthere for a long time. An operator with static electricity may dis-charge electricity through a component when he/she touches theconductor and causing damage.

Wear an antistatic wrist strap (the other end of wrist strap must bewell grounded) before touching the equipment or holding a plug-inboard, circuit board, Integrated Circuit (IC) chip or other devices,to prevent human static electricity from damaging sensitive com-ponents.



Laser

Laser:

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

High Temperature

Danger:

Avoid touching the surface area of some devices due to high tem-perature 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 replacingrelated parts, to avoid damage to the fan or related devices.

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

Hoisting HeavyObjects

Cable Installation Flow

Figure 25 shows the cable installation flow.

FIGURE 25 CABLE INSTALLATION FLOW


Chapter 6 Cables Installation

Note:

� The trunk should be selected according to the on-site situation.

� The installation of GPS jumper is determined by whether GPSantenna is installed on site.

� The alarm cable is determined by alarm input modes, usuallyinstalling the dry contact cable and RS232/RS485 cable.

Cable Layout Principle

When laying out cables, observe the following principles:

� For an equipment room installed with supports and antistaticfloor, downward cabling can be used. That is, cables can bewired through the floor interlayer or cable tray. If upward ca-bling is used, lay the cabling rack above the cabinet top to runcables.

� Determine the cabling positions in advance. Cables should bearranged orderly without damages to external skin.

� For external cables such as power cable, tail table, trunk cable,and other signal cable, use wire fasteners to bind those of thesame type into one bundle. The spacing between bundles is20 cm.

� Ensure smooth and even cable bends. The minimum bendingradius should be at least 60 mm.

� Cables must be bound neatly and orderly with even spacingbetween cable ties.

� Cables within troughs may not be bound. However, they shouldbe straight without overlapping and remain inside the troughs.Bundle the cables at places where they come into or go out ofa trough and where direction is changed.

� For trunk cables, do not pull them tensely when laying themfrom cabinet to transit rack. Avoid stretching the cables anddo not cut off the excessive part completely. Bundle the cablesin troughs or on the raised floor based on cabinet. Ensure thatthe cables are straight without overlapping. After the layout,the cables should be arranged in order without damages toexternal skin. In addition, reserve margins if necessary.

� During cable layout, attach one label special for each cable,such as engineering cable, trunk cable, optical fiber, or powercable, at the position 2 cm from the terminal. The label con-tent should indicate the directions of both ends. The format iscabinet number+board number+socket number.

� The cable layout should provide convenience for maintenanceand future expansion.



Installing Power CableSteps 1. Estimate the cable length and route along the cable tray be-

tween the power cabinet and the BS8800 GU360. The powercable and the protective ground cable should be separately ar-ranged and banded from other cables. The banding distanceper segment is 200 mm. The length of about 0.2 m~0.5 m atboth cable ends is reserved.

Note:

The power cable and the protective ground cable should beintact and without joints in the middle of cables.

2. Make sure the power supply output is cut off.

Danger:

OverviewMain Antenna Feeder SystemComposition

The antenna feeder system consists of input/output ports from thecabinet to the antenna. It is used for transmitting the base sta-tion’s transmission signal and received signal. If the base stationsystem is configured with Tower Mounted Amplifier (TMA), the an-tenna feeder system should also contain power supply circuits ofTMA.

For a site that covers three sectors, usually one sector uses twosingle-polarized antennas, in other words, totally six antennas areused to implement space diversity reception. For the two direc-tional antennas in a sector, one is used for transmitting downlinksignal from the base station to MS and receiving uplink signal fromMS, and this antenna is connected with duplexer and combinerthrough feeder cable. The other antenna is only used for receivinguplink signal from MS, and it is directly connected with the receiv-ing preselective filter through feeder cable.

Observed from antenna to cabinet, the antenna feeder systemconsists of the following components:

� Antenna

� TMA (optional)



� Antenna jumper

� Main feeder cable

� Grounding clip

� Lightning protector

� Cabinet-top jumper

The antenna feeder system composition is shown in Figure 36.

Antenna Jumper InstallationAntenna Jumper InstallationPrecautions

To guarantee the antenna system reliability, the following itemsshould be noticed during the process of installing 1/2” super flex-ible jumper.

� Single bend: the minimum bend radius is 125 mm.

� Multiple bends: the minimum bend radius is 200 mm.



� The redundant antenna jumper can be made into semicircle ofwaterproof corner with a radius larger than 125 mm, or circlewith a radius larger than 200 mm.

� Fasten connectors. After the entire antenna feeder system haspassed test, seal connectors with waterproof tapes.

Installing Antenna Jumper

Context The antenna jumper is a super flexible jumper connecting the an-tenna and the main feeder cable. Usually, the 1/2” super flexiblejumper is used for the mobile base station system. The jumperconnector type depends on the antenna and the main feeder cable,normally, the jumper’s two connectors are both male DIN type.

Steps 1. Select an appropriate jumper route, which should be reliable,convenient, and as short as possible. Make sure that rain waterdrops from the jumper’s middle part, not from the connector.

2. Connect the jumper connector to the antenna connectorwith an appropriate torque. A typical connection torque forDIN-type connector is 1.7 N•m, and the maximum connectiontorque can not exceed 2.3 N•m. Make sure that the connectorsdo not bear any lateral force, as shown in Figure 45.

FIGURE 45 CONNECTING JUMPER

3. Connect the main feeder cable connector to the jumper con-nector with an appropriate torque (the same as that specifiedin the previous step). Make sure that the connectors do notbear any lateral force.

4. Fix jumper with feeder cable clips, as shown in Figure 46. Thedistance between feeder cable clips is not more than 0.76 m.When the wind speed exceeds 160 km/h, appropriately shortenthe distance between feeder cable clips.



FIGURE 46 FIXING JUMPER WITH FEEDER CABLE CLIP

5. Implement performance measurement for antenna and feedercables and make sure that the system is running normally. Af-ter doing these, seal connectors with self-adhesive waterprooftape and PVC tape.

END OF STEPS

room as shown in Figure 47.

FIGURE 47 DRILLING HOLES ON THE WALL

2. Seal feeder cable holes according to the number of feeder ca-bles required, as shown in Figure 48.



FIGURE 48 SEALING FEEDER CABLE HOLES

3. Install the feeder window as shown in Figure 49.

FIGURE 49 INSTALLED FEEDER WINDOW

END OF STEPS



Main Feeder InstallationMain Feeder Installation Precautions

The following items should be noticed during the process of in-stalling feeder cable:

� When installing feeder cables on the iron tower, use the pulleyblock to hoist feeder cables.

� Paste the main feeder cable label 0.3 m away from the feedercable end.

� Hoist feeder cable to the platform on the tower, and fix thefeeder cable’s upper end to appropriate position to avoid itfalling down from the tower.

� Feeder cables should be arranged tidily without being crossed.Mark both ends of each feeder cable before performing feedercable layout.

� Draw the actual cabling route before performing feeder cablelayout to avoid feeder cable crossing.

� The minimum bending radius of feeder cable must be not lessthan 20 times that of the main feeder cable. For single bend,the minimum bend radius is 90 mm, while for multiple bends,the minimum bend radius is 200 mm.

� The maximum distance between feeder cable clips (HANGER)is 1.65 m. It is advised to install one feeder cable clip everyone meter.

� For feeder cable at the antenna, there should be a straightpart of 30 cm to 40 cm to guarantee that the feeder cableconnector does not bear any force, and certain feeder cablemargin should be left for possible adjustment. If the pole onthe building roof is single-polarized, it is advised to arrange thefeeder cable margin at the corner of the horizontal cable rackon the lower pole.

� Fix feeder cable with feeder cable clip if conditions permit. Donot use cable tie to bind feeder cables.

Main Feeder Indoor Layout Principles

The following lists principles for main feeder indoor layout:

� A 12–hole feeder cable hermetic window has four big holes.Each big hole contains three small holes, and each small holehas one feeder cable passing through.

� Feeder cables in the three small holes in one big hole are ar-ranged sequentially according to engineering label ID, and arelaid out either clockwise or anti-clockwise.

� The feeder cable layout in the hermetic window should be easilyexpanded. Capacity expansion should not change the original



feeder cable layout, it is only allowed to add feeder cables in thehermetic window or change jumper connections in the cabinet.

� The feeder cable layout in hermetic window should facilitatelaying feeder cables on the cable rack and feeder connectionswith the cabinet. Feeder cables should be parallel and have nocross.

Installing Main Feeder Cable

Context The main feeder cable is connected with two jumpers:

� The jumper connected with antenna

� The jumper connected with cabinet

The main feeder cable adopts the 7/8” foaming feeder cable. Usu-ally, the two connectors are both female DIN connectors.

The following mechanical performance should be guaranteed whentransporting and installing main feeder cables:

1. Single bend: the minimum bend radius is 400 mm.2. Multiple bends: the minimum bend radius is 450 mm.3. The maximum hoisting feeder cable length of a hoisting trawl

is 60 m.

Steps 1. Measure and cut the feeder cables into various lengths accord-ing to actual requirements. Leave necessary feeder cable mar-gin.

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

3. Use the hoisting trawl or pulley to lift the feeder cable up to theiron tower, as shown in Figure 50. Fix the main feeder cablewith feeder cable clips and cut excess length of the main feedercable.

FIGURE 50 HOISTING TRAWL



4. Complete the main feeder cable installation and make the mainfeeder cable DIN connector at the other side.

5. Use support for the main feeder cable every 1.2 m, and adda few supporting points at the bends. Keep the feeder cableclose to the pole, and add cable support along the pole everycertain distance, as shown in Figure 51.

FIGURE 51 FIXING FEEDER CABLE

6. If the iron tower is floor-mounted, then ground the feeder ca-ble at 0.5 m ~ 1 m above the bend where it connects theantenna or leaves the tower body, and outside the entrance tothe equipment room. If the feeder cable length is more than60 m, ground it in the middle part. Connect the feeder cable’smetal outer layer with the grounding busbar through ground-ing clips. Lead a tin-plated copper wire or zinc-plated flat steelout from the grounding busbar, with a cross-sectional area notless than 95 mm2, and connect it to the grounding point of theiron tower.

END OF STEPS

Postrequisite Ensure the following items during the connector installationprocess:

1. Keep the feeder cable straight for at least 150 mm.2. Use special purpose tools to cut feeder cables.3. Use ruler to accurately measure the feeder cable length.4. Do not tear the outer conductor when using knife to strip the

feeder cable’s outer layer.5. Keep connector unmoved when using spanner to fasten con-

nector. Rotate the connector fastening component to screw theconnector tightly.

6. Label both ends of the main feeder cable before the cableis laid on the iron tower, to distinguish the sector it belongsto and transmitting/receiving features during cable connectionprocess.



Leading Main Feeder Cable Indoors

Context Figure 52 and Figure 53 show the two methods of leading mainfeeder cable indoors. It should be guaranteed that the main feedercable does not cause rain water coming into the equipment room.

FIGURE 52 LEADING MAIN FEEDER CABLE INDOORS (METHOD 1)

3. Feeder clip

FIGURE 53 LEADING MAIN FEEDER CABLE INDOORS (METHOD 2)

1. Feeder window2. Cable rack

3. Feeder clip

Steps 1. Unscrew the fastening hoop iron of feeder window to a properposition. Pull out hermetic covers of small holes through whichthe feeder cable passes through.

2. Lead the main feeder into the equipment room. When lead-ing the main feeder into indoor cable rack from outdoor cablerack, it is required that two installation workers, one indoorand the other outdoor, cooperate together to fulfil the task. Ithelps avoid damaging the main feeder as well as other indoorequipments due to improper force during the main feeder cableinstallation process. After the main feeder is pulled to specifiedposition, screw the fastening hoop iron tightly.



3. Cut the main feeder cable. Before cutting the main feeder cableand after the main feeder cable is cut, make sure that labelson the main feeder are intact.

Note:

When cutting the main feeder cable, the following factors areconsidered for selecting the cutting position:

� Cabinet installation position

� The length of jumper on the cabinet top

� Lightning protector configuration

� Installation position of the lightning protector rack

� The bend radius of main feeder cable

� Cable layout in the equipment room should be clean andtidy

4. Make indoor connector of the main feeder cable.

5. Connect the main feeder cable with the lightning protector.

Note:

� For lightning protector without grounding cable, directlyconnect the lightning protector to the main feeder duringthe installation process. Make sure that the lightning pro-tector is insulated from the cable rack.

� For lightning protector with lightning protector rack, ad-just each main feeder cable carefully during the installationprocess. Make sure that the main feeder cable connectoris well connected with the lightning protector.

END OF STEPS

Installing Lightning ProtectorContext All cables that are led into the equipment room from antenna must

be connected to the lightning protector, and the lightning protectoris connected to the grounding cable, as shown in Figure 54.

3. Test the feeder cable performance to ensure it is normal. Af-ter doing that, seal the connectors with self-adhesive tape asshown in Figure 56.



FIGURE 56 SEALING LIGHTNING PROTECTOR

Note:

� During installation, all surfaces contacting the ground mustbe clean, dry, and not oxidized.

� The working frequency marked on the lightning protectormust be consistent with that of the base station system.

END OF STEPS

Installing Grounding KitContext The grounding kit is used to connect the feeder cable’s outer con-

ductor with the tower or grounding cable. It leads current to theground in case of the system being attacked by thunder. Usually,the grounding kit is installed near the top of the antenna’s feedercable or the feeder cable end at the bottom of the tower, or theentry through which the feeder cable comes into the equipmentroom. For feeder cables higher than 60 m, the grounding kit isinstalled in the middle part of the feeder cable.

Steps 1. Fix the grounding end of the grounding kit. Mark the ground-ing kit installation position on 7/8” feeder cable, and strip thefeeder cable sheath at the position for installing the groundingkit.

Waterproof Outdoor Joints

Prerequisites The antenna feeder system SWR test is passed.

Context � It is advised to adopt the 3–3–3 mode in waterproof sealing forfeeder cables. In other words, three layers of insulating tapeare used inside, three layers of waterproof tape are used in themiddle, and three insulating tape are used outside.

� The insulating tape inside facilitates removing connectors, thewaterproof tape in the middle prevents water and moisture,and the outside insulating tape is used to keep the middle tapeinside and protects the connector.

� The 3–3 mode can be adopted if the connecting point needsnot be removed. In other words, three layers of waterprooftape are used inside and three layers of insulating tape areused outside.

Steps 1. Connect the antenna jumper and the main feeder cable con-nector, and screw them tightly.

2. Perform waterproof handling for the connector. Wrap the con-nector with three layers of electrical insulating tape first. Thenwrap it with three layers of waterproof insulating tape, tightenthe tape to make the tape width 3/4 ~ 1/2 of the original width.After doing that, wrap the connector with another three layersof electrical insulating tape.

i. When wrapping the waterproof tape, start wrapping fromthe lower part the connector, and use about 200–mm tapeto fill in the concave part, as shown in Figure 74.

FIGURE 74 WRAPPING WATERPROOF TAPE (1)

ii. Extend the tape length twice of the original length. Use60–cm waterproof tape for each connector and wrap theconnector for three layers. The wrapping direction must be



same as that of screwing the feeder connector to preventthe connector from loosening.

iii. Wrap the tape layer by layer as shown in Figure 75, thenwrap the tape in the opposite direction, the outside layeroverlapping inside layer about 1/2 of the tape width. Fi-nally, wrap the tape in the opposite direction for three lay-ers. Do not cut the tape during wrapping, and the lengthof wrapping tape must exceed the connector for about 20mm.


iv. After wrapping the waterproof tape, press the tape to en-sure the tape and feeder/feeder connector are agglutinatedtightly, as shown in Figure 76.


v. Wrap the electrical insulating tape out of the waterprooftape for three layers. Make the outside layer overlap insidelayer 1/2 of the tape width.

vi. Press the electrical insulating tape and the waterproof tapeto ensure that the two are agglutinated tightly.

vii. Use the black anti-ultraviolet tie to bind the two ends oftape to avoid tape aging and falling off, and cut the redun-dant tie, as shown in Figure 77.



Note:

Considering the effect of expanding with heat and contract-ing with cold, reserve 3 mm ~ 5 mm extra tie to preventthe tie from falling off.
