Fig. 68 Connection of an EFOP fan-out-panel
Tips
– Use the same mains socket to connect the power supply of the com-
munication 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.
