Test Since the relays are not monitored in the hardware or software, the relays
must be tested at regular intervals on proper functioning. The frequency of
the test cycle is subject to the safety requirements of the operator but it must
be carried out at least every six months.
During the test it must be ensured that the relays can actually switch! The
following settings are required:
Ground-fault relay menu 6.6.1.2 relay test "on"
NGR-fault relay menu 6.6.2.2 relay test "on"
Trip relay menu 6.6.3.2 relay test "on"
