air switch +24V end, if measurement value shows 24（±3） V, connection is correct.
And then close designated branch switch.
WARNING: Do not bundle power cables with other cables. They must be cabled
separately.
2.6 Cabling Requirements in the Equipment Room
The following installation requirements must be followed in order to prevent accidents or
damages to the equipment.
 In the equipment room, transmission cables on the cable ladder should be cabled
separately from power cables and grounding wires, without any cross connection.
The cabling should be done in a tidy and nice order. Excessive cables should be
bundled up with cable ties and then placed on the cable ladder in the equipment
room. Attached white cable ties should be used in an internal less than 400mm.
 The RF feeders between the cable ladder and the RF feeder, any elbow should
be kept smooth without cross connection. The elbow angle should be ≥90º.
 Some cables, such as the GPS cable from the cable ladder to the cabinet, 7D-FB
feeder, Ethernet cable, power cables of the BTS and the cabinet’s grounding
wires, should be vertically led into the cabinet’s cabling holes from the cable
ladder.
 Both ends of Ethernet cable should be labeled clearly. Make sure to check the
Ethernet cable to ensure good contact;
 Both ends of the ground wire should be connected with specific connectors
(copper lug). After checking the connectors, wrap the connection between the
grounding wire and the connector with insulation tape. On the grounding wire
provided upon delivery, no connection is allowed in the middle. Both ends should
be tightened with bolts;
 On the power cables configured along with delivery, no connection is allowed in
the middle. After connection, label the power cables clearly close to the switch.
Close the branch switch on the power distribution cabinet to check the power to
be connected to the BTS. If the power is correct, switch it off and connect it to the
BTS.
 Power cable and signal cable in the cabinet should be distributed separately,
leading power cable (connect to circuit breaker) and protection grounding cable
should be laid in the cabling troughs’ outboard on the left of the cabinet (see
behind), GPS cable should be laid in the cabling troughs’ middle, and Ethernet
cable should be laid in the cabling troughs’ indoor. Base station power cable
should be laid in the cabling troughs on the right of the cabinet.
