Troubleshooting Tips
???? Contactor Not Energizing
Check coil voltage (A1-A2).
Verify control circuit (fuse, switch, wiring).
???? Overheating or Buzzing Noise
Ensure tight terminal connections.
Check for voltage fluctuations.
???? Frequent Contact Wear
Use higher duty rating (AC-4) if switching frequently.
