Error F3
Cause
Suggested solution
The internal DC fault current module has detect-
ed a DC fault current.
When this error occurs for the first time, the charging
procedure is interrupted for 30 seconds and then restarted
automatically. If the error occurs again immediately, the
charging procedure is terminated permanently: A new
charging procedure is only possible after disconnecting the
vehicle from the wallbox.
There is possibly an electrical fault in the charging system
of the vehicle. Do not charge the vehicle, and immediately
contact a qualified specialist repairer. In addition, consider
the notices provided in the operating manual for the vehicle.
Error F4
Description
Flash pattern
Per cycle, the green battery icon flashes once,
followed by the blue power symbol flashing three
times.
The red warning symbol remains ON.
Cause
Suggested solution
Bus communication is not available inside the
wallbox, or within the Controller-Extender group
installation.
Disconnect the wallbox from the electricity supply and
check the data cabling. Then switch the electricity supply
back on. This should automatically reset the error.
Should the error persist, take the wallbox out of operation
(see page 53) and contact a qualified specialist electrical
contractor to resolve the error.
Error F5 (variants with charging socket only)
Description
Flash pattern
The blue power symbol flashes four times per cy-
cle while the green battery icon remains OFF.
The red warning symbol remains ON.
Cause
Suggested solution
The self-test performed by the wallbox has de-
tected an error because the charging cable plug
could not be locked inside the charging socket of
the wallbox.
The wallbox automatically reinitiates the self-test after 30
seconds: after two failed self-tests, the charging procedure
is terminated permanently.
Should the error occur again, check the position of the plug
in the charging socket, or unplug it and plug it back in.
Should the error persist, take the wallbox out of operation
(see page 53) and contact a qualified specialist electrical
contractor to resolve the error.
