After commissioning, the relays for the external power-off
can be defined on the display as normally closed or nor-
mally open relays.
Dry contact
The inverter has one dry contact. The contact is closed
when the relays energize.
Event
Description
Disabled
The functions for the dry contact are
switched off.
On Grid
Inverter is connected to the mains
grid.
Insulation
Insulation error.
Alarm
An error, failure or warning message
is present.
Error
An error message is present.
Fault
A failure message is present.
Warning
A warning message is present.
An event can be assigned to the dry contacts can be set
on the inverter display after commissioning.
The default setting for both contacts is "Disabled".
