Why is my Riello UPS operating from the battery when there is mains voltage?
The Riello UPS might be operating from the battery because the input voltage is outside the permitted tolerance range for mains operation due to a problem with the mains. Wait for the input mains voltage to return within the tolerance range; the UPS will then automatically switch back to mains operation. Another potential cause is the intervention of the input circuit breaker. If present, reset it by pressing the button on the back of the UPS, after checking that there is no output overload.

If the display is on but the load isn't powered, first, ensure the UPS is not in standby mode by pressing the “ON” button on the front panel. Also, check if the STAND-BY OFF mode is selected, as this mode only powers loads during blackouts, and change the mode if needed. Finally, verify the connection to the load.
