CHAPTER ONE: INSTALLATION PROCEDURE FOR EMTS PROJECT

If material arrive site, the SBC should use a checklist to check

the equipment and the ensure that the materials are complete

as printed on the MR or DN.

If everything is confirmed ok, the SBC should unpack the

materials gently to avoid damaging of the equipment.

Ensure no damaged or missing item. If there is any damaged or

missing item, the SBC should inform Huawei engineer on site

and indicate such on the check list. The SBC will get a

corresponding amercement according to the damaged or

missing item.

INSTALLATION PROCEDURE

The installation

procedure is best

described in two folds:

The equipment (BTS)

part procedure

The RF part procedure

THE EQUIPMENT(BTS) PART PROCEDURE.

The

installation flow

chart for this

part is as

follows:

HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential Page 10

INSTALLING THE BASE, RFC AND APM30H

Check the plinth and

mark out according

design.

The base of the

Battery cabinet and the

RFC/APM30H cabinet

must be separated by a

distance of at least 10cm.

Ensure that you use

expansion bolt to make

the base firm on the plinth.

HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential Page 11

INSTALLING THE BATTERY & RFC CABINET

Ensure you install

the battery cabinet on

the left side and the

RFC cabinet on the

right as shown in the

picture below:

APM30H & RFC

IBBS battery

banks set up.

HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential Page 12

INSTALLING EARTHING CABLES.

The grounding cable

of diameter 16mm^2 is

used to interconnect

the two cabinets and

must be connected to

the earthing terminal

(Bar) as shown below: To the earthing terminal on-site.

HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential Page 13

NOTES; During this installation the SBC is not expected to use

short cables that may lead to joining of the cables.

The SBC should ensure tight connections at all

terminal points on the grounding bar.

The SBC must apply denso-paste at all the grounding

terminal points.

SBC must route the cable through a PVC pipe to

make the installation neat and protect the cables.

All earthing cables must be routed through the cable

hole accordingly.

HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential Page 14

CHECKING OF THE BOARDS AND MODULES

The SBC should check the boards e.g.

DRFU, modules e.g. PSU, PMU etc that are

pre-loaded in the cabinet from factory, if they

are complete and well positioned in the

cabinet according to configuration. If at this

stage and there is any alteration from the

physical connection, please report to office.

HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential Page 15

PART TWOTHE RF & MW PART PROCEDURE

Generally , the RF and MW part of the installation involves the

installation of the following:

The jumpers at the BTS end of the line.

The feeder cable which can be 7/8 or 5/4 inch diameter coaxial cable

depending on the height of the tower.

The coaxial connectors at both ends of the cable which can be male

or female type.

The jumper cables at the antenna end on the tower

The antenna which can be single band or dual band depending on

the configuration of the site.

CHAPTER THREE POWERING UP STAGES OF BTS 3900A OUTDOOR

Note:

Make sure all necessary ATS setting for Generators and a 16mm 4 core, 4 wire power

cable

connecting from ATS to ACDB is well connected as design , check all phases for

Generators 1& 2 in ATS if they are balanced and confirm the accuracy of the voltage

needed to supply the equipment on-site using multimeter.

Step 1 :

Check BTS 3-phases cables on ACDB if voltage supplied is according to range of AC

voltage

needed between 240V using millimeters to check . Make sure you switch ON AC breaker

For BTS inside ACDB.

Check also the 3-phases cables of BTS AC (EPS) box that came from ACDB ,make sure

supplied voltage is according to range of AC voltage needed between 240V using

multimeter to check.
