Connecting plug at the upper side of the device for plug connection to the basic unit or to
Socket at the upper side of the device for the plug connection to additional modules
Remote ON/OFF and signaling contacts
When the buffer module with double-layer capacitors is completely charged (LED "O.K."
lights green), power failures of 4 s or 10 s can be buffered with a load current of 40 A. The
buffer time is appropriately increased for lower load currents.
