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 position and negative poles may damage the RRU or cause personal injury.
