What to do if Online USV ZINTO A 800 does not switch on after pressing the power button?
- MMitchell HardyAug 1, 2025
If your Online USV UPS doesn't switch on after pressing the button, ensure you keep the button pressed until the acoustic signal stops, which usually takes about 3 seconds. Also, check the cable connection, paying attention to the seating of the connectors. If the issue persists, there might be a short circuit or overload in the UPS output. In this case, remove all loads, restart the UPS, and reconnect the loads one by one, making sure they are not faulty. If the mains wall socket is faulty, please contact an electrician. If the internal fuse is faulty, please contact your dealer.
