32 CHAPTER 2: INSTALLING THE SWITCH
Figure 10 RPS Connection to the Switch
When the RPS is connected to the switch, you can move the circuit
breaker in the RPS to the closed (on) position and the switch will be
powered by the -48V DC power.
The -48V DC power takes priority over the AC mains and powers the
switch if it is connected.
Connecting the
Earthing Cable
Use the earthing cable that accompanies your switch if the length is
suitable. Alternatively use the earthing cable specification as defined in
Appendix C on page 127.
The earthing cable is only required if the switch is powered by the RPS
only.
The recommended cable length should not exceed three metres (9.84
feet).
