Possible Causes

Detected potential rise on earth/neutral, Incorrect TN‑C‑S earthing configuration, Faulty PEN fault detection module, Loose neutral or earth connection upstream

How to Fix / Troubleshooting

Shock hazard: PEN faults can make exposed metal parts live. Do not bypass PEN fault protection.

  • Step 1 – Stop using charger: Turn off the dedicated breaker immediately.
  • Step 2 – Check with electrician: Have a qualified electrician verify the supply earthing arrangement and integrity of the neutral and earth conductors.
  • Step 3 – Confirm correct installation: Ensure the Shell Recharge charger was installed according to local regulations for PEN fault detection (e.g., no shared neutrals, correct bonding).
  • Step 4 – Reset after verification: Once the supply is confirmed safe, power the charger back on and see if E15 clears.
  • Step 5 – If E15 persists with verified good supply: The internal PEN fault detection module or associated circuitry may be defective and must be replaced by an EVSE technician.
