8.5 Resetting the Operation Inhibition after Detection of an
Arc Fault
If the red LED is glowing and the event number 4301 is shown on the display and/or in the event
list on the user interface of the inverter, the inverter has detected an electric arc and interrupts feed-
in operation.
There are two options for resetting the operation inhibition:
• Reset the operation inhibition by tapping twice on the enclosure lid of the Connection Unit.
• Reset the operation inhibition by parameter setting.

Connection Unit
1.
Danger to life due to electric shock
• Disconnect the inverter from any voltage sources (see the inverter installation manual).
2. Ensure that the PV modules, the connected DC cables and the connecting terminal plate for the
DC connection are not defective.
Repair or replace defective PV modules, DC cables or connecting terminal plate for the DC
connection.
3. Recommission the inverter (see inverter installation manual).
4. If the event with the event number 4301 appears in the display, immediately tap on the
enclosure lid twice in quick succession. Here, the operation inhibition can only be reset if the
event is showing in the display when you begin tapping.
☑ This effects resetting of the operation inhibition and the inverter will start feeding in again. At
the same time, the blue LED can flash rapidly, indicating that there is an active WPS function.
The WPS function deactivates automatically after a short period.
