Class 3 Status
Codes
Class 3 includes status codes that may appear during grid power feed operation and do
not cause permanent interruption of the grid power feed operation.
After automatic disconnection from the grid and waiting for its conditions to return to those
stipulated, your inverter will try to resume grid power feed operation.
240 Arc detected
The status code is displayed
for approx. 4 seconds.

241 Arc detected
The status code 241 is dis-
played directly after 240; the

setting the inverter.

the "Enter" key.
