Charger’s enclosure or mounting bracket is loose, causing vibration or movement when plugging/unplugging.

Safety: A loose charger can stress internal wiring and connectors.

• Inspect mounting hardware: Remove the charger cover if needed and check all mounting screws and brackets. Tighten to the torque specified in the manual.
• Upgrade anchors: If installed on masonry or drywall, ensure appropriate wall plugs or anchors are used. Replace with heavier-duty anchors if necessary.
• Check cable strain relief: Confirm that cable glands and strain reliefs are properly tightened so that cable movement does not pull on internal terminals.
• Re-mount if substrate is weak: If the wall material is failing, relocate the charger to a more solid surface or add a backing board.
