    Tips: There is no any display on the panel and UPS does not work after the starting up of UPS.

    Judging from the phenomenon, it is the fault of electric supply input, battery, and electric supply detection and battery voltage detection circuit.

    1. Check whether the electric supply input fuse is burned out.
    2. Check whether the battery fuse is burned out and whether the electric supply input fuse is OK. Because the UPS output and display will be shut down when some UPS cannot detect battery voltage.
    3. Check whether the electric supply detecting circuit is working normally if the battery fuse is OK. If it doesn’t work normally and UPS doesn’t has starting up function without electric supply, UPS output and display will be shut down. If the electric supply detecting circuit is working normally, please check whether the battery voltage detecting circuit is normal.
