How to Fix / Troubleshooting

Safety first: Turn off power before tightening any mounting hardware.

Check wall fixings: Ensure all mounting screws are tight and appropriate wall anchors are used.
Add support: If the wall is thin or flexible, add a backing board or additional supports.
Secure conduits: Clamp any conduits or cables so they do not transmit vibration to the charger.
Professional internal check: A technician can tighten internal brackets and ensure no components are loose.
Monitor over time: If vibration worsens or is accompanied by noise or smell, stop using the charger and have it serviced.

Charger’s enclosure vibrates or rattles when the contactor closes or during charging.
