Tips
– Use the same mains socket to connect the power supply of the communication server and
the power supply of the EFOP fan-out-panel to the mains power. This prevents an unwanted
switchover in the event of a mains failure on the EFOP fan-out-panel only.
– In redundancy operation, connect the communication server and the APS2 auxiliary power
supply unit to separately protected mains power. This will further enhance the system's
operating reliability.
