Possible Causes
Supply voltage above EVBox rated limit, Incorrect grid configuration (e.g., wired for 400 V single‑phase), Faulty input voltage sensing circuit on main board, Neutral missing or loose in supply
How to Fix / Troubleshooting
Danger: Overvoltage can damage the charger and vehicle. Only a qualified electrician should measure and correct supply voltage issues.
- Verify supply voltage: Have an electrician measure line‑to‑neutral and line‑to‑line voltages at the EVBox input terminals. Compare with the charger rating plate.
- Check wiring configuration: Confirm that the EVBox is wired according to the installation manual (single‑phase vs three‑phase, correct neutral connection, correct phase rotation where applicable).
- Inspect neutral conductor: Ensure the neutral is present, correctly sized, and firmly connected at both the distribution board and the EVBox terminal block.
- Power cycle after correction: Once supply issues are corrected, turn the charger off for 2 minutes, then restore power and test.
- If E006 remains with correct supply: The input voltage sensing circuit on the main control board may be faulty and the board should be replaced.
