Why does my CDP UPO 11-2 AX UPS keep beeping and show overload?

  natashadixonAug 15, 2025
  If your CDP UPS beeps every second and the LCD display shows specific icons flashing, it indicates an overload. This means the devices connected to your UPS are drawing more power than it can supply. You should remove some of the connected devices from the UPS output. If the UPS is locked in Bypass mode after repetitive overloads, remove excess loads, then shut down the UPS and restart it.

  Jenna SteinAug 31, 2025
  If your CDP UPS is showing specific icons flashing on the LCD display and the alarm is sounding every 2 seconds, it indicates that the line and neutral conductors of the UPS input are reversed. To fix this, rotate the mains power socket by 180° and then connect it to the UPS system. Also, this can mean that the external or internal battery is incorrectly connected, so check if all batteries are connected well.

  If your CDP UPS shows no indication and no alarm, even when the mains is normal, it could be due to these reasons: * The AC input power is not connected well. Check if the input power cord is firmly connected to the mains. * The AC input is incorrectly connected to the UPS output. Ensure you plug the AC input power cord into the AC input correctly.
