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 3kAin 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.

Tower Mountinga

The shielding layer of a DC cable must be grounded properly to the maintenance cavity of the BTS3900E. Therefore,

external grounding is not required on the tower.

The shielding layers of the E1 cable and alarm cable are grounded on the BTS side with connectors. Therefore, grounding

clips are not required on the tower.

If cable clips, cable ties, or pig tail clips are used to ground the cables on the power supply device and transmission device

side, grounding clips are not required.

4. Grounding Requirements of External Cables

1. Requirements of BTS3900E Installation and Port Surge Protection

The BTS3900E and its auxiliary devices must be installed within the 45 protection

angle of the lightning rod. The BTS3900E must be grounded to the nearest grounding point on the tower

(within 1m from where the BTS3900E is installed).

None of the external ports of the BTS3900E require external surge protection units.

The BTS3900E and its transmission and power supply devices must be connected

to the same grounding system and share the grounding grid of the site.

ports of the transmission devices should meet the following requirements: The surge protection level of the FE port should be greater than orequal to 7.5kA (8/20us) in al l-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-groundcommon mode. Otherwise, a surge protection unit should be installed

near the E1 port.

Rooftop Mountingb

The shielding layer of a DC cable must be grounded properly to the maintenance cavity of the BTS3900E. Therefore,

external grounding is not required on the rooftop. The shielding layers of the E1 cable and alarm cable are grounded on the BTS side with connectors. Therefore, grounding

clips are not required on the rooftop. Insulating tapes or L-shaped plastic pipes must be used to protect cables from damage.

If cable clips, cable ties, or pig tail clips are used to ground the cables on the power supply device and transmission device

side, grounding clips are not required.

4. Grounding Requirements of External Cables

1. Requirements of BTS3900E Installation and Port Surge Protection

The BTS3900E and its auxiliary devices must be installed within the 45

protection angle of the lightning rod. The BTS3900E must be grounded to the nearest metal pole or rooftop

surge protection belt (within 1m from where the BTS3900E is installed).

None of the external ports of the BTS3900E require external surge

protection units.

The BTS3900E and its auxiliary devices are installed on the same rooftop.

External cables must be routed in lightning-free areas and cannot beshort-circuited to the surge protection belt on the rooftop or to the external

conductors on the building.

2. Lead the fiber tails labeled 1A and 1B of theoptical cable into the corrugated pipe by 160mm.3. Wrap the corrugated pipe and optical cable with

the color tape.4. For the tower made of steel pipes, tie the blackjacket to the corrugated pipe at the position 150 mm

away from the color tape, and then lift the opticalcable up to the tower.5. For the tower made of angle steel girders, carry

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 beforeinstalling the optical cable.

Binding Waterproof Labels

Attach waterproof labels to corresponding cables

The default position for attaching a waterprooflabel is 2cm away from the connector. In special

scenarios, the label can be attached at anotherposition to avoid a bend of a cable or a positionwhere installation is difficult. Generally speaking,

all the waterproof labels should be attached neatlyand consistently.

Both ends of a cable near connectors should beattached with waterproof labels, and the silkscreen

on the label should be in consistent with the

corresponding cable.For details, see the precedingfigure.
