How to Fix / Troubleshooting

Safety first: Turn OFF the breaker immediately if you see water inside the charger or suspect moisture intrusion. Do not use the charger until it has been inspected.

Steps to try:

  • Drying: Allow the charger to dry naturally in a dry environment. Do not use heat guns or hair dryers on the enclosure.
  • Inspect exterior: Look for cracks, missing screws, or gaps around conduit entries and mounting points.

When to call a technician: A technician should open the unit, inspect for corrosion or damage, replace any compromised gaskets or housings, and verify insulation resistance before returning the charger to service.
