What to do if the display on my Riello UPS does not light up?
- KKyle RodriguezAug 18, 2025
If the display on your Riello UPS doesn't light up, there could be several reasons: * The input switch might be open. In this case, close the input switch located on the back of the UPS. * The main connection cable might be missing or not properly connected. Ensure the power cable is correctly connected. * There might be no mains voltage (blackout). Check if the power reaches the socket by testing with another device like a table lamp. * The upstream thermal protection might have tripped. Reset the thermal protection, but first, check that there is no output overload to the UPS.
