What does it mean when Riello UPS display shows A30, A32 and the CPS does not start up?
- M
  marymasonSep 8, 2025
  If the Riello UPS display shows codes A30 or A32 and the CPS does not start up, it could be due to: * Ambient temperature < 0°C. Heat the environment, wait for the heat sink temperature to rise above 0°C and then start up the CPS. * Fault in heat sink temperature probe. Activate the maintenance bypass (SWMB) if present, turn the CPS off and back on again and exclude the maintenance bypass. If the problem persists, contact the nearest service centre.

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.

What to do if Riello UPS display is off, the fans are off but the load is powered?

  Tyler MorrisonSep 6, 2025
  If the Riello UPS display is off, the fans are off, but the load is powered, there may be a fault in the auxiliary power supplies and the CPS is in bypass supported by the redundant power supply. Activate the maintenance bypass (SWMB) if present. Switch off the CPS, wait for a minute and turn the CPS back on. If the display does not turn on or if the sequence fails, contact the nearest service centre, leaving the CPS in manual bypass mode.
