7. Troubleshooting
If you encounter issues with your charger, refer to the following common problems and solutions:
Issue: Charger displays "E04" or a Ground Fault Error.
This error typically indicates a grounding issue with the electrical outlet. The charger has a built-in safety feature that detects improper grounding.
Solution: In some cases, this error can be bypassed if your electrical system does not provide a ground wire (e.g., older NEMA 10-30 outlets). Follow these steps to bypass the ground fault detection:
- Ensure the charger is unplugged from the vehicle.
- Long press the "function" button on the charger's control box.
- Navigate through the menu options until you see "GND" or "Grounding".
- Select "No grounding" or the equivalent option to bypass the ground fault detection.
- Reconnect the charger to your vehicle and attempt charging again.
Note: Bypassing ground fault detection should only be done if you are certain about your electrical system and understand the potential risks. Consult a qualified electrician if unsure.

Other Issues:
- Charger not powering on: Ensure it is securely plugged into a live electrical outlet. Check the circuit breaker.
- Slow charging: Verify the selected amperage setting on the charger. Ensure your vehicle and electrical system can support higher charging rates.
- Charging interrupted: Check for loose connections at both the outlet and the vehicle. Ensure no external factors (e.g., power fluctuations) are affecting the charge.
