Possible Causes
Insufficient ventilation around charger, High ambient temperature, Loose high‑current terminals causing localized heating, Undersized supply cable causing I²R losses
How to Fix / Troubleshooting
Safety first: If you smell burning or see smoke, disconnect power immediately.
- Check installation clearances: Ensure the charger has the minimum clearances specified by Garo and is not enclosed in a small, unventilated space.
- Inspect terminals: With power OFF, open the charger and tighten all high‑current terminals (input and output). Look for signs of overheating.
- Verify cable size: Have an electrician confirm that the supply cable cross‑section matches the configured current.
- Reduce current: Temporarily lower the maximum charging current in the settings to reduce heat until a permanent fix is implemented.
