Possible Causes

Incorrect current setting higher than supply rating, Short circuit or partial short in tethered cable, Internal contactor or wiring fault causing high current draw, Vehicle drawing more current than allowed by pilot signal due to vehicle fault

How to Fix / Troubleshooting

Safety first: Overcurrent can cause fire. Do not repeatedly reset without identifying the cause.

  • Verify current setting: Check DIP switches or configuration app to ensure the maximum current is set to match the circuit breaker and cable size.
  • Inspect cable and plug: Look for melted insulation, burn marks, or kinks in the tethered cable. Replace the cable if any damage is found.
  • Test with another vehicle: If possible, test the charger with a different EV. If E010 only occurs with one vehicle, the vehicle’s onboard charger may be faulty.
  • Check breaker size: Confirm that the upstream breaker is correctly rated and not nuisance-tripping due to other loads on the same circuit.

If E010 recurs with multiple vehicles and a good cable, an internal wiring or contactor fault is likely and the unit should be inspected by a Siemens-qualified technician.
