How to Fix / Troubleshooting

Safety first: If you smell burning or see smoke, stop charging immediately and turn off the breaker.

  • Reduce current: In the installer or user settings, temporarily reduce the maximum charging current and monitor temperature.
  • Inspect plug and socket: After cooling, check for discoloration or deformation of the Type 2 plug and socket. Replace any heat-damaged components.
  • Tighten terminals: With power off, retorque all high-current terminals on the input block, contactor, and socket/cable connections to manufacturer specs.
  • Check cable sizing: Confirm that the supply cable cross-section is adequate for the configured current and run length.
  • Ventilation: Ensure the charger has adequate airflow and is not installed in a confined, unventilated space.
  • Replace overheated parts: Any melted or charred socket, cable, or terminal block must be replaced.
