Charger is installed outdoors and shows signs of rust on mounting hardware or around cable entry.

Safety first: Corrosion near electrical connections can lead to poor grounding and overheating.

• 1. Inspect for water ingress:
  • Check inside the housing (with power off) for rust or corrosion on terminals and boards.
• 2. Replace corroded hardware:
  • Use stainless steel mounting screws and washers.
• 3. Seal penetrations:
  • Apply appropriate outdoor-rated sealant around mounting holes and cable entries, avoiding vents.

Severe internal corrosion warrants replacement of the charger to maintain safety.
