What to do if the display on my Riello UPS does not light up?
- J
  Jennifer AdamsAug 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.

Why is my Riello UPS operating from the battery even when there is mains voltage?
- W
  William WilliamsAug 20, 2025
  Your Riello UPS might be operating from the battery despite mains voltage for these reasons: * The input voltage is outside the permitted tolerance range for mains operation, meaning there's a problem with the mains. Wait until the input mains voltage returns within the tolerance range; the UPS will automatically return to mains operation. * The upstream thermal protection might have tripped. Reset the thermal protection, being cautious to check for any output overload to the UPS.

What to do if the display is on but the load is not powered by my Riello UPS?

  If the display is on but your load isn't powered by the Riello UPS, consider the following: * The UPS might be in stand-by mode. Press the “ON” button on the front panel to power the loads. * The stand-by off mode might be selected. This mode only powers the loads during a blackout, so you'll need to change the mode. * There might be no connection to the load. Check the connection to the load.

Why is my Riello UPS buzzer sounding and showing codes A54, F50, F51, F52, F53, L50, L51, L52, or L53?

  If the buzzer on your Riello UPS is sounding continuously and the display shows one of the codes A54, F50, F51, F52, F53, L50, L51, L52, or L53, it means that the load applied to the UPS is too high. Reduce the load to within the threshold of 100% (or user threshold in the case of code A54). If the display shows a lock: remove the load and switch the UPS off and back on again.

  If your Riello UPS buzzer is sounding continuously and the display shows F04 or L04, the temperature of the dissipators inside the UPS is too high. Ensure that the ambient temperature where the UPS is located does not exceed 40°C.

What does error code A62 mean on my Riello UPS?
- D
  Daniel GonzalezAug 30, 2025
  If your Riello UPS displays the code A62, it indicates that the batteries are missing, or the battery box is missing or not connected. On the versions with an additional battery charger in place of the batteries, check that the Battery Box is inserted and connected to the UPS correctly.

  If the buzzer sounds continuously and the display shows F53 or L53 on your Riello UPS, it indicates a fault on one or more of the utilities powered by the UPS. Disconnect all the utilities, switch the UPS off and back on again, and then reconnect the utilities one at a time to identify which one is faulty.

  If your Riello UPS displays error codes C01, C02, C03, C05, or C05, it means a remote command is active. If this is unwanted, check the status of the command inputs on any optional contact card.
