CAUTION:
• Before installing RRU power cables, ensure that the upper-level circuit breaker is disconnected,
and the power cable has no voltage.
• A drip loop is required for the position between the RRU port and the cable, preventing rain from
damaging the RRU.
• When installing the RRU power cable, connect the power cable to the RRU connector first and
then to the power equipment connector. Incorrect connection sequence or reverse connection of
positive and negative poles may damage the RRU or cause personal injury.
Procedure
1. Connect the female fast connector (pressfit type) at one end of the RRU power cable to the
power supply socket on the RRU, as shown in Figure 1.
