Explanation
Charging not possible
NOTE: The CUPRA 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 measurement, 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.
Charging not possible
The wallbox has detected a current leakage to ground (earth)
caused by the vehicle.
• If the vehicle is connected to the wallbox, disconnect it.
Wait until the wallbox is idle before reconnecting your vehicle.
• If the vehicle is not connected to the wallbox, have the
wallbox switched off at the power supply cabinet. Have
the wallbox switched on again for a reboot.
• If the error still occurs, inspect the charging cable and the
connector for dirt or damage.
• If the error is not corrected, contact your customer support.
Charging not possible
• Have the settings of the DIP-switches checked to match
the configurations shown in this manual.
Charging not possible
The output relays are welded together.
WARNING
Risk of electric shock
If the wallbox is powered on, there may be live voltage
in the charging connector.
1. Have the wallbox switched off at the power supply cabinet.
2. If the vehicle is still connected to the wallbox, unplug the
charging cable from your vehicle and attach the cap on
the cable connector.
3. Have the wallbox switched on again for a reboot.
4. If the error still occurs, have the wallbox switched
off permanently and secured. Call your customer
support and have the wallbox replaced.
