Charging cable with control unit - ground fault breaker
The control unit for the charging cable has a built-in ground fault breaker that protects the car and the user from electric shocks caused by system faults.
If the control module's built-in ground fault breaker is tripped then the car symbol illuminates with red constant glow - check the 230 VAC socket.
Important
The control unit's earth fault switch does not protect the 230 VAC socket.
