Why does my UPS beep?

Although uninterruptible power supplies (UPS) are designed to be silent, sometimes they will make a beeping sound. The reason why your CyberPower UPS unit beeps might differ depending on the situation and type of equipment you have. Below are some examples of what could cause the unit to start making noise:

  1. Beeping twice every 15-45 seconds: This is an indication that your UPS unit is running on battery power only and it needs to plugged in or waiting for power to be restored.
  2. Rapidly beeping: The UPS is running out of battery power and needs to be plugged in.
  3. Long solid beep: An overload condition exists, such as too many devices connected to an outlet.

  1. Make sure the wall outlet is turned on and working correctly. To test try plugging device into another outlet. Try plugging something into the wall outlet like a lamp or fan and see if it works. Alternatively the charging cable could be faulty and need replacing.
