Ground fault breaker in charging cable
The control unit for the charging cable charging cable has a built-in ground fault breaker that protects the car and the user from electric shocks caused by system faults.
Warning
Charging the high-voltage battery must only take place with grounded and approved 230 V sockets (alternating current). If the capacity for the socket or fuse circuit is unknown, ask a licensed electrician to check the capacity. Charging above the capacity of a fuse circuit may lead to fire or damage the fuse circuit.
Warning
- The charging cable's overvoltage protection helps to protect the car's charging system, but cannot guarantee that overload will never occur.
- Never use visibly worn or damaged electrical sockets. This could cause fire or serious injury.
- Never connect the charging cable to a cable extension.
- Maintenance or replacement of the high-voltage battery must only be performed by a trained and qualified Volvo service technician.
- Do not use a charging cable that has not been recommended.
- An external timer must not be used between the charging cable and the electrical socket.
- One or more adapters must not be used between the charging cable and the power socket.
Important
The ground fault breaker does not protect the 230 V socket (alternating current)/electrical installation.

LED lamp
If the control unit's built-in ground fault breaker is tripped then the LED lamp illuminates with a red constant glow - check the 230 V socket (alternating current).

Important
- Check the capacity of the socket.
- Other electronic equipment connected to the same fuse circuit must be disconnected if the total load is exceeded.
- Do not connect the charging cable if the socket is damaged.
