Resetting the Operation Inhibition after Detection of an Arc Fault


Qualified person

If the red LED is glowing and the event number 4301 or 4302 is shown in the event list on the user interface of the inverter, the inverter has detected an electric arc and interrupts feed-in operation.

Procedure:

  1. DANGER

    Danger to life due to electric shock

    1. Disconnect the inverter from any voltage sources (see the inverter installation manual).
  2. Ensure that the PV modules, the connected DC cables and the terminal block for the DC connection are not defective.
  3. Repair or replace defective PV modules, DC cables or terminal block for the DC connection.
  4. Recommission the inverter (see inverter installation manual).
  5. Open the user interface Establishing a connection to the user interface).
  6. Log into the user interface as an Installer Logging In and Out of the User Interface).
  7. To reset the operation inhibition, select the parameter Reset operating data and set it to Reset operation inhibition or select the parameter AFCI switched on and set it to No and then back to Yes.
  • This effects resetting of the operation inhibition and the inverter will start feeding in again.
