How to Fix / Troubleshooting
Safety first: An RCD that does not test correctly must be treated as non-functional. Do not use the charger until resolved.
- 1. Attempt manual test: Press the RCD test button (if accessible) with the unit powered. If it does not trip, the RCD is faulty.
- 2. Power off and inspect: Isolate power and inspect the RCD module for signs of damage or contamination.
- 3. Professional testing: Have an electrician perform an RCD trip time and current test with appropriate instruments.
- 4. Replace RCD module: If tests fail, replace the internal RCD/DC leakage module with the correct myenergi-specified part.
- 5. Retest after replacement: Verify correct operation of the test button and automatic self-test before returning the charger to service.
