RED Steady LED

Steady red light — Charging fault or authentication issue

Zaptec · Pro

What does RED Steady LED mean?

A steady red light can indicate a charging fault, such as a problem with the cable or vehicle, or another authentication failure. It could also point to a deeper electrical issue within the installation.

Common Causes

  • Charging fault on the charging cable.
  • Charging fault on the vehicle.
  • Authentication failed (RFID tag/charging card not connected to user profile).
  • Problem with electrical fuses or circuit breaker.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Disconnect the charging cable from the station. Observe if the status indicator turns green.

  2. 2

    If it turns green, reconnect the charging cable. If it turns red again and charging doesn't start, the fault may be with the cable or vehicle.

  3. 3

    If the light does not turn green after disconnecting the cable, check the circuit breaker in the distribution cabinet for the charging station.

  4. 4

    Verify that your RFID tag or charging card is correctly linked to your user profile in the Zaptec Portal.

  5. 5

    If possible, try charging a different electric vehicle to help determine if the issue is with the charger or the vehicle.
