Note
For an external power supply use the optional auxiliary power supply unit
APS2 exclusively.
Tip
In redundancy operation, connect the communication server power sup-
ply and the APS2 auxiliary power supply unit to separately protected
mains power. This will further enhance the system's operating reliability.
Mounting the auxiliary power supply APS2
The auxiliary power supply APS2 is supplied with a fastening kit that includes two
fastening plates and 6 screws. If a fan-out-panel FOP or EFOP is already fitted, the
auxiliary power supply can be installed behind the connection panel.
The following diagram shows the fan-out-panel FOP from below with the auxiliary
power supply fitted.
