How to Fix / Troubleshooting

Safety first: Do not repeatedly power cycle the charger during a firmware update process unless instructed by Schneider documentation.

  • Check status LEDs: Some EVlink models indicate bootloader or firmware status via specific LED patterns. Refer to the manual to interpret them.
  • Stable power: Ensure the supply voltage is stable and within specification before attempting any recovery.
  • Firmware recovery: Follow Schneider Electric's official procedure for firmware recovery, which may involve a USB stick, SD card, or service tool. Use only firmware images provided for your exact EVlink model.
  • Avoid DIY flashing: Do not attempt to load unofficial firmware or modify images; this can permanently damage the control board.
  • Board replacement: If firmware cannot be recovered, the Schneider EVlink control board will need replacement by an authorized technician.
