How to Fix / Troubleshooting

Safety first: Frequent resets can indicate underlying electrical issues. Turn off power before internal inspection.

  • Check ambient temperature: Ensure the charger is not exposed to direct sun or high ambient temperatures beyond its rating.
  • Inspect ventilation and dust: Clean vents and internal components to improve cooling.
  • Surge protection: Have an electrician verify that appropriate surge protection is installed on the supply to the EVlink charger.
  • Firmware update: Consult Schneider Electric for firmware updates that may address stability issues.
  • Power supply/control board replacement: If resets continue, a technician should test the auxiliary power rails and replace the power supply module or control board as needed.
