To provide -48 V DC power supply for the site, you need to install the DCDU-03C. TheDCDU-03C converts one -48 V DC power input to multiple 48 V DC power outputs for thebase station. The APM200 needs to be installed only when there is only 220 V AC powersupply at the site. The APM200 converts 220 V AC power input to multiple -48 V DC poweroutputs for the base station. Ensure that the power distribution equipment such as the APM200 and DCDU-03C has an

independent power switch to control the power-on and power-off of each BBU and RRU. When the 2T2R is used, the remaining N-type connectors are protected by waterproof caps.

The PGND cable of the BBU isyellow-green or green. The sectional

area of the PGND cable is 6 mm2

(10AWG).The PGND cable is

connected to the BBU through a OT

terminal or a two-hole OT terminal

(M4) and to the grounding bar

through an OT terminal. The PGND

cable of the BBU should be created

at the site.

e Installing the GPS Clock Signal Cable

When the BBU3900 is configured with a USCU, the GPS clock signal cable is connected to

the GPS port on the USCU. When the BBU3900 is not configured with a USCU, the GPS

clock signal cable is connected to the GPS port on the BMPT.

ProtectSurge

When the BBU is installed in a 19-inch cabinet, ground the surge protector. The

grounding cable should not be longer than 300 mm, and the cross-sectional area of thegrounding cable is 6 mm2. The grounding cable is terminated with OT terminals on both

ends.

the insulating tape and waterproof tape

RF jumper

Before installing the RF jumper,

measure the VSWR of the antenna

system. For details, see "Measuring

the VSWR of the Antenna System"

on P21.

You need take

insulation and

waterproof

measures only for

the RF jumpers

connected to an

outdoor RRU.

Connection Relation between the 4T4R RRU and Four-port Antenna

Identify the RF ports with their silkscreens,

and connect the jumpers according to the

connection relation shown in the figure

above.

Installing the Outdoor Cable Transfer Box

Measuring the VSWR of the Antenna System

When the distance between the RRU and the DCDU-03C orAPM200 ranges from 60 m to 180 m, install an outdoor cabletransfer box at the RRU.

The length of the cable which between the outdoor cabletransfer box and the RRU is 3 m to 5 m.

Measure the VSWR of the antenna system using theBroadband Site Master.

Measure the VSWR in the position where the antennasystem is connected to the RF port of the RRU.

Never connect an antenna system with a VSWR of1.5 or higher to the RRU.

Hoist the RRU and other installation parts onto the tower.

Tie the installation parts with a rope at one end and tie the RRU with

the other end

Traction rope

Lifting rope

Do not lift only the handle.

Installers A climb onto the tower and

fixes the crown block onto the support of

the tower platform and puts the hoist

thread through the crown block.

Installer C uses the lifting rope to tie the

RRU and the installation parts according tothe figure and uses the traction rope to tie

a knot at the handle of the RRU.

Installer B pulls down the hoist thread,

and installer C pulls the leading thread

outwards to prevent the RRU and the

installation parts from colliding the tower.4.

Installers A and B hold the RRU and the

installation parts and loosen the knot.

When hoisting the RRU, prevent it from

colliding with the tower.
