What to do if no power reaches the load with Riello UPS?
- D
  diana25Aug 22, 2025
  If no power reaches the load when using a Riello UPS, check the following: * Ensure the load is properly connected to the output terminals. * Verify the CPS is not in standby mode by running the start-up sequence. * Confirm the operating mode; the STAND-BY OFF mode only powers loads during a blackout. If this mode is selected, change the operating mode. * If the CPS is malfunctioning and the automatic bypass is out of use, insert the maintenance bypass (SWMB) and contact the nearest service center.

  Darlene MillerAug 30, 2025
  If the Riello UPS display shows the code A39, the batteries have failed the periodic efficiency test. It is recommended to replace the batteries of the CPS, since they are no longer able to maintain the charge for a sufficient autonomy. The replacement of the batteries must be carried out by qualified personnel.

Why Riello UPS connected to the mains does not switch to stand by mode?
- K
  kimberly15Aug 25, 2025
  If your Riello UPS, connected to the mains, does not switch to standby mode (and the display does not light up), consider the following potential causes: * A missing connection to the input terminal. Connect the mains to the terminals following the indications in the paragraph “POWER CONNECTION”. * A missing neutral connection. Connect the mains to the terminals as explained in the paragraph “POWER CONNECTION”. * The isolator (SWIN) is open. Close the isolator. * Mains power missing (blackout). Make sure the mains power is present. If necessary, perform battery start-up to power the load. * Intervention of the upstream protection device. Restore the protection. Warning: make sure there is no overload or short circuit on the CPS output.

  Kimberly GibsonAug 23, 2025
  If the Riello UPS display shows nothing or provides incorrect information, the display may have power supply problems. To resolve this, activate the maintenance bypass (SWMB), completely shut down the CPS and wait a few seconds. Turn the CPS back on and check if the display operates normally. If the fault persists, contact the nearest technical support centre.
