Charger displays E06 and refuses to start; often logged as a "PEN fault" or "PME fault" in the app.

Safety first: PEN/PME faults can create dangerous touch voltages. Do not bypass or disable PEN fault protection.

• Confirm earthing arrangement: Verify that the charger is configured for the correct earthing system (PME, TT, etc.) as per the Rolec installation manual and local regulations.
• Check supply integrity: Have an electrician test the supply neutral and earth at the origin. Any instability or high potential difference must be resolved by the DNO or a qualified electrician.
• Inspect PEN fault module: With power isolated, check the Rolec PEN fault detection module and its connectors for damage or loose wiring. Some modules have status LEDs—refer to Rolec documentation.
• Power‑cycle and retest: After confirming wiring and configuration, reboot the charger. If E06 clears temporarily and returns, the module may be oversensitive or failing.
• Replace module if necessary: If supply tests are normal but E06 persists, replace the PEN fault detection module with the correct Rolec‑approved part.
