Error messages during operation with the vehicle
Under some circumstances, malfunctions and disruptions may occur that prevent the
proper charging of the vehicle according to IEC 61851.1, Mode 3. The Wallbox detects
possible errors on the part of the vehicle independently and shows them using the
indicator LEDs.
To represent certain errors, the indicator LEDs will flash in a specific, repeating pat-
tern.
The following error codes are displayed:
LED-SEQUENCE (FLASHING) ERROR DESCRIPTION
The vehicle makes an unauthorized demand on the
charging procedure
Communication with the vehicle is disrupted
A DC fault current has been detected
The EVSE 5X1 / 5X3 reinitiates the charging procedure every 30 seconds, checking
communications with the vehicle. If the error recurs, the indicator LEDs continue to
show the error code. No charging occurs in this operating state.
WARNING!
If the Wallbox continues to show error messages during operation with
the vehicle, please always contact your service partner for the vehicle. It
is possible that maintenance must be carried out before the vehicle can
be charged again using the EVSE 5X1 / 5X3.
Disruptions to the operation of the wallbox and solutions
For safe operation, depending on model variant, the eMH1 has an integrated DC fault
current detector and/or a residual current circuit breaker (RCCB), which detects re-
sidual currents that may occur and disconnects the entire Wallbox from the electricity
supply for your personal protection. The RCCB is located under the lockable cover
shield: This ensures that it can only be operated by authorized users.
PLEASE NOTE:
All EVSE model variants must be protected during operation either
by an integrated or external RCCB.
Depending on the country, for model variants without DC fault current
detection, an external type B RCCB must be set aside in the domestic
power distribution box.
