The charger’s enclosure or mounting bracket is loose, vibrating, or rattling when plugging or unplugging the cable.

Safety first: Turn off power before tightening any screws that might be near live parts.

Steps:

• External check: Gently test the charger by hand to identify where movement occurs.
• Tighten fixings: Use appropriate tools to tighten the mounting screws into the wall anchors. Do not overtighten and crack the housing.
• Upgrade anchors: If the wall material is weak (e.g., drywall), consult the installation manual for suitable anchors or consider relocating to a more solid surface.
• Technician check: Ensure that internal components are also securely mounted and not contacting the enclosure.
