Possible Causes
Loose wall mounting hardware, Vibrating contactor or transformer, Resonance with building structure, Unbalanced three-phase load causing mechanical hum
How to Fix / Troubleshooting
Safety first: Turn off power before tightening any mounting hardware.
- Check mounting screws: Ensure the EVlink charger is firmly secured to the wall or mounting post with appropriate anchors.
- Add damping: If mounted on a thin wall, consider adding rubber washers or a backing board to reduce resonance.
- Internal check: With power OFF, verify that internal components (contactor, transformers) are tightly fixed to their brackets.
- Phase balance: For three-phase units, have an electrician verify that the load is balanced and supply voltages are symmetrical.
