‡ Error detection and solutions.
Should a malfunction occur during operation of the smart Wallbox, this is shown by the indicator LEDs
on the lower part of the housing cover as an error code. To indicate certain operating states, the LEDs
may...
... be illuminated
(continuous ON)
... flash
... be extinguished
(continuous OFF).
The following chapter describes how you recognize operating states as well as error codes and which
measures you can take to resolve them.
Operational disruptions and solutions.
For secure operation, the wallbox must be protected by external MCB(s) and RCCB in the domestic power
supply. To take suitable measures and restore operation in case of malfunction, you must first clearly
identify the type of error. The following errors may occur:
Type of error Possible cause Suggested solution
LEDs are not
functioning.
The wallbox does not
have a power supply.
The power supply is interrupted within the domestic
electrical infrastructure: Check the upstream MCB(s)
and RCCB and switch them back on if required. If the
error repeats or occurs permanently, contact your lo-
cal smart technical support.
The wallbox has not
been connected in ac-
cordance with the re-
spective type of mains
power connection for
the country of instal-
lation.
Check your mains connection scheme using the over-
view of country-specific mains connection schemes on
page 29 in this manual or on the
www.yourwallbox.de
website using the following link:
www.yourwallbox.de/Mains_Connection_Schemes
If necessary, please change your mains connection
scheme according to this overview.
An internal fault has
occurred in the wallbox. The wallbox must be replaced. In this case, please con-
tact your local smart technical support.
The electric vehicle
is not recognized.
The charging cable is
not properly plugged
into the vehicle or the
wallbox. Remove the charging connector from the vehicle and
plug it back in: Should the error persist, check the
Mode 3 charging cable and contact your local smart
technical support.
The indicator LEDs
show an error
message.
The wallbox detects a
malfunction.
Please reinitiate the charging procedure: If the error
repeats or occurs permanently, take the wallbox out
of operation (see “Taking the product out of and back
into operation.” on page 21) and contact your local
smart technical support.
