Charger enclosure vibrates or rattles when the contactor pulls in or during charging.

Safety first: Turn off power before tightening internal components.

• Check wall mounting: Ensure all mounting screws are tight and anchored into solid structure per Zencar installation guide.
• Inspect internal brackets: With power OFF, tighten screws securing the main power contactor, power supply, and terminal blocks.
• Secure cables: Use cable ties or clamps to prevent heavy cables from pulling on the housing or components.
• Test after tightening: Restore power and start a charge to confirm vibration is reduced.
• If vibration persists from contactor: Consider replacing the main power contactor if it appears mechanically worn.
