Protection

ground_fault_protection loss of protective earth detection - display shows 'PE not connected!' when impedance exceeds limits
over_current isolates if the vehicle draws more than 125% of the maximum current
over_temperature thermal limit reduces charging current, then trips if overheating continues
over_voltage trips at more than +12% of 230 V nominal for five seconds; auto-reset within nominally 230 V +/-10%
