If Huawei does not provide the transmission devices, the interconnection

ports of the transmission devices should meet the following requirements:

• The surge protection level of the FE port should be greater than or

equal to 7.5kA (8/20us) in all-to-ground common mode. Otherwise, a

surge protection unit should be installed near the FE port.

• The surge protection level of the E1 port should be greater than or equal

to 3kA in pair-to-ground differential mode or 5kA in pair-to-ground

common mode. Otherwise, a surge protection unit should be installed

near the E1 port.

over the power cable. Connect power cables to the AC surge

protection box.

c

Close the cover plate of the surge protection box and tighten

the screw to 1.4N·m using an M4 Phillips screwdriver. d

Ensure that the insulation layer of each

power cable is fastened using clips.

1. Lead the power cable between the surge protection

box and the external power device through the PG

connector labeled IN. Connect the OT terminals of the

blue, brown, and yellow/green core wires to the Lin,

Nin, and GND ports on the surge protection box

respectively.

2. Lead the power cable between the BTS3900E

and the AC surge protection box through the PG

connector labeled OUT. Connect the OT

terminals of the blue, brown, and yellow/green

core wires to the Nout, Lout, and GND ports on

the surge protection box respectively.

3.Tighten the thread-lock sealing nut, and then

use a wrench to tighten the PG connector to

ensure it is waterproofed properly.

the optical cable onto the tower when climbing up to

the tower.

6. After the optical cable is lifted up to the tower,

remove the color tape and corrugated pipe before

installing the optical cable.

Binding Waterproof Labels b

Attach waterproof labels to corresponding cables

The default position for attaching a waterproof

label is 2cm away from the connector. In special

scenarios, the label can be attached at another

position to avoid a bend of a cable or a position

where installation is difficult. Generally speaking,

all the waterproof labels should be attached neatly

and consistently.

Both ends of a cable near connectors should be

attached with waterproof labels, and the silkscreen

on the label should be in consistent with the

corresponding cable. For details, see the preceding

figure.
