If the earth leakage circuit breaker has been activated, it may have been an earth leakage, short circuit or overcurrent situation.
An 'earth leakage trip' means that an earth leakage current has been detected. This usually indicates there is an issue with the leakage current of the installation or of the vehicle.
We advise to contact the installer or operator of the charging station for inspection and possible repair. Are you the operator? You can submit a 'Request for Service' ticket via support.alfen.com.
