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 corresponding to the as-
signed conductor (L+ or L-) will be displayed.
