8. Remove the internal electronic com-
ponents cover. Set the S1 rotary en-
coder to the 0, 1 or F position.
Ensure that the S3 rotary encod-
er remains set to the 0 position.
9. Replace the internal electronic com-
ponents cover. Close and lock the
housing cover. Switch the power sup-
ply back on via the upstream MCB(s)

During start-up, the wallbox will
load the new settings from the
memory and then return to nor-
mal operating mode (see page
12 and following).
In some circumstances, an error may occur when changing the preset charging current, which will be
indicated by the LED display after you have switched the power supply to the wallbox back on in step 3.
Error description LED status
> The settings could not be saved in the memory.
> The wallbox was set to an electrical current that is not allowed for this
model variant: The preset current is therefore not altered.
In both cases, please continue with step 6 in order to then restart the wallbox for normal operations.
