Additional details: Under-voltage monitoring in three-phase networks (each phase against neutral) with fixed set threshold, fixed set hysteresis, and integrated test button. It has been specifically designed for emergency lighting systems according to DIN VDE 0108. The device can also be used to monitor a single phase. All unoccupied inputs must be connected to the connected phase. If there is a back voltage caused by the load that exceeds the set threshold, no fault message will occur.

Good indication: Relay is energized (contacts 11-14 and 21-24 closed), LED is off.
Fault indication: Relay has dropped out (contacts 11-14 and 21-24 open), LED is on.
Button press: Relay drops back (contacts 11-14 and 21-24 open), LED lights up.
Connection with screw terminals.
