Charging not possible
This error occurs when the temperature inside
the wallbox is too high.
— If the wallbox does not recover from the critical
temperature state, disconnect it from the car.
Wait for at least one hour for the wallbox to cool
down.
— If this error occurs more often, make sure
that the wallbox is protected from heat
sources (direct sunlight).

Charging not possible
NOTE: The ID. Charger detects if it is correctly
connected to ground by measuring the L1 to PE
(Protective Earth) voltage.
— Have voltage between L1 and PE
measured multiple times:
A – If voltage is close to 0 V, then L1 and N
might be swapped.
B – If the voltages are different for each measure-
ment, the ground connection is possibly floating.
Possible solutions:
— For TN and TT grounding schemes (not applicable
to 1-phase without neutral): Have the wallbox
checked for a proper ground connection.
— In case of IT grid or 1-phase without
neutral, have the ground monitor functionality
disabled via DIP-switch 5 of Group A.
— If the error still occurs, and a safe operation
of the wallbox and its upstream installation is
ensured, have the ground monitor functionality
disabled via DIP-switch 5 of Group A.
