      If the alarm list of your Riello UPS shows one or more of the following codes: L01, L02, L03, L04, L06, L07, L08, it could be due to: * Faulty loads applied: Remove the load. Insert the maintenance bypass SWMB (if present), and turn the UPS off and then on again. * Fault in the input or output stage of the UPS: Activate the maintenance bypass SWMB (if present) and turn the UPS off and then on again.

      If your Riello UPS is completely off (display not turned on), consider the following: * **Mains Voltage:** Check that the mains voltage is present. If needed, power on the UPS from the battery to power the load. * **Input Terminals:** Ensure the mains are correctly connected to the terminals. * **Input Breaker:** Verify the input breaker (SWIN) is closed. * **Neutral Connection:** The UPS requires a neutral connection to function. Connect the mains to the terminals as indicated in the Installation manual. * **Upstream Protective Device:** Reset the protective device, but first, check for any overload or short-circuit at the output of the UPS.

      If the load connected to your Riello UPS is not powered, check the following: * **Output Terminals:** Ensure the load is correctly connected to the output terminals. * **Output Isolator:** Verify that the output isolator (SWOUT) is closed. * **Stand-By Mode:** Make sure the UPS is not in stand-by. Execute the power-on sequence. * **Stand-By Off Mode:** Check if STAND-BY OFF mode is selected, this mode only powers the loads when a black out occurs. Change the operating mode if needed. * **UPS Failure:** If there is a UPS failure and automatic bypass is out of order, insert the maintenance bypass SWMB (if present) and call your local service center.

      If the alarm list of your Riello UPS shows one or more of the following codes: A18, it could be due to: * Protective device upstream from the bypass line open (only if bypass is separate): Reset the upstream protective device. Check that there is no overload or short circuit at the output of the UPS. * Bypass switch open (SWBYP only if bypass is separate from mains): Close the bypass switch (SWBYP) if present.
