How to Fix / Troubleshooting
Safety: Low insulation resistance can indicate a potential shock or fire hazard. Do not ignore this error.
- 1. Inspect for moisture: Check the charger enclosure, cable gland, and socket for signs of water ingress or condensation. Dry the area thoroughly and improve sealing if necessary.
- 2. Examine cable: Look for cuts, abrasions, or crushed sections on the output cable. Replace the cable if any damage is found.
- 3. Clean interior (qualified only): With power isolated, open the charger and gently remove any dust, insects, or debris that could bridge conductors. Use dry compressed air if available.
- 4. Perform insulation test: A qualified technician should perform an insulation resistance test between live conductors and earth on the output circuit.
- 5. Replace faulty module: If external causes are ruled out, the internal insulation monitoring circuit may be defective and require replacement of the relevant module.
