Possible Causes
Tripped upstream breaker or RCD, Blown internal fuse on Garo main board, Failed auxiliary power supply, Loose supply wiring at input terminals
How to Fix / Troubleshooting
Safety first: Treat the unit as live until proven otherwise. Only a qualified person should open the enclosure.
- Check supply breaker: Verify that the dedicated breaker and any RCD feeding the charger are ON and not tripped.
- Test supply voltage: Have an electrician confirm that correct voltage is present at the charger's input terminals.
- Inspect internal fuse: With power OFF, open the charger and locate any internal fuses on the main board or power supply module. Replace only with the exact type and rating specified by Garo.
- Check wiring tightness: Ensure that the supply conductors are firmly clamped in the input terminal block.
- Power supply replacement: If supply is present but the charger remains dead, the internal auxiliary power supply or main board is likely faulty and must be replaced.
