Possible Causes

Missing phase at input terminal block, Incorrect phase rotation (L1/L2/L3 swapped), Loose phase conductor, Faulty upstream breaker or fuse on one phase

How to Fix / Troubleshooting

Note: This applies to three-phase Mini EV Home Chargers.

  • Verify supply type: Confirm that the charger model is three-phase and that it is connected to a three-phase supply as specified on the nameplate.
  • Check upstream breakers/fuses (electrician): Ensure all three phase breakers or fuses feeding the charger are ON and intact. Replace any blown fuses.
  • Measure phase voltages (electrician): At the charger input, measure L1–L2, L2–L3, and L3–L1. All should be within the specified range and similar. If one phase is missing, correct the supply.
  • Correct phase sequence (electrician): If the charger requires a specific phase rotation, swap two phases at the input terminal block to correct sequence. Always follow Mini’s wiring diagram.

If E06 persists with correct three-phase supply, the phase detection circuit on the main PCB may be defective and require replacement.
