Remote Control Unit (RCU)
The RCU provides remote control of Powerwave WRHs. It contains an integrated mobile phone, modem and
power supply backup. The RCU is installed in the bottom front of the cabinet, on top of the PSU as illustrated
in Figure 4-2.
The RCU is connected to P130 on either an RCI or FON. A jumper is required between pins 1 and 2 on the
R
CI if the P130 ca
ble connector is disconnected. If a main power failure occurs, the unit has a battery with
enough capacity for sending a number of alarms.
