Application
The 3UG30 82 monitoring relay has been designed for insulation
monitoring in ungrounded, purely DC networks with or without
filtering.
It is mainly used to monitor ungrounded DC voltage networks as
well as to monitor battery-powered systems.
Supply voltage
Due to the electrical insulation of the supply voltage and the
measurement circuit, the relay can be used for DC networks in
which the auxiliary voltage is either supplied externally or where
the network to be monitored also serves as the power supply.
Note:
If the monitoring relay is supplied with an AC 230 V voltage, for
example, the terminals A1 and L+ as well as A2 and L- must not
be connected with each other!
