Mercedes-Benz Wallbox
| Error detection and solutions
Please follow these steps to change the maximum charging current setting of your Mercedes-Benz Wallbox:
Working step
LED status
Note
1. Switch off the power supply for the wall-
box via the upstream MCB(s) and RCCB.
-
2. Remove the internal electronic compo-
nents cover. Set the desired value using
the S1 rotary encoder (see table on page
16).
On the S1 rotary encoder, select the
position for the desired electrical current.
Leave the S3 rotary encoder in the 0 posi-
tion.
3. Replace the internal electronic compo-
nents cover. Close and lock the housing
cover. Switch the power supply back on
via the upstream MCB(s) and RCCB.
The wallbox will now restart in setup mode
and register the settings of the two rotary
encoders.
4. The wallbox now restarts in setup mode.
ca. 10
minutes
If the settings have been successfully
saved after approx. 10 seconds, all LEDs
will be on.
5. Switch off the power supply via the up-
stream MCB(s) and RCCB.
-
6. Remove the internal electronic compo-
nents cover. Set the S1 rotary encoder to
the 0, 1 or F position.
Ensure that the S3 rotary encoder remains
set to the 0 position.
7. Replace the internal electronic compo-
nents cover. Close and lock the housing
cover. Switch the power supply back on
via the upstream MCB(s) and RCCB.
During start-up, the wallbox will load the
new settings from the memory and then
return to normal operating mode (see
page 11 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.
