How to Fix / Troubleshooting

Safety: Moisture inside electrical equipment can cause shorts and corrosion.

  • Disconnect power: Turn off the breaker before inspecting or drying the unit.
  • Dry the unit: Open the front cover (if allowed by ABB) and gently dry internal areas with a clean cloth and allow to air dry completely. Do not use high heat.
  • Inspect seals: Check the door gasket, cable gland, and any knockouts for gaps or damage. Replace damaged gaskets or glands with ABB-approved parts.
  • Use holster: Always store the connector in the provided holster to protect it from rain and snow.
  • Corrosion check (technician): A technician should inspect for corrosion on terminals and boards; clean or replace affected components.
