5.4.2 Alarm relay alarm assignment "r1" and "r2" and LED assignment
In the alarm assignment, each alarm is assigned to the corresponding alarm relay with the
setting "on". The LED indication is directly assigned to the alarms and is not related to the
alarm relays.
In the event of an asymmetrical insulation fault, only the alarm corresponding to the as-
signed conductor (L+ or L-) will be displayed. .
