    What to do if my LEGRAND UPS displays a DIESEL MODE?
    • W
      wwallSep 13, 2025
      If your LEGRAND Power Supply displays DIESEL MODE, it indicates that the auxiliary contact which activates the diesel generator connected to the UPS is closed, imposing this operating mode. Wait for the diesel generator to stop as soon as the mains voltage is restored. Also, check the connection of the auxiliary contact which signals the diesel generator start, to terminals XD1/XD2. If the alarm persists, contact our Technical Support Service.
