5.4.2 Relay alarm assignment "r1" and "r2" and LED assignment
In the alarm assignment, each alarm is assigned to the respective relay with
the setting "on". The LED indication is directly assigned to the alarms and is
not related to the relays.
In the event of an unsymmetrical insulation fault, only the alarm correspond-
ing to the assigned conductor (L1/+ or L2/-) will be displayed. Otherwise, the
messages for L1/+ and L2/- are shown together.
