Why is my Eaton UPS beeping every 2 seconds?
- T
  tstevensAug 13, 2025
  Your Eaton UPS is beeping every 2 seconds because it's running on battery power due to abnormal input voltage. This happens when the input voltage is too high (greater than 149V for 120V models or greater than 290V for 230V models) or too low (less than 30V). If possible, correct the input voltage. The UPS will continue to operate on battery until the condition is corrected or the battery is completely discharged.

Why does my Eaton 5115 UPS operate in battery mode even with normal power?
- W
  William GravesAug 20, 2025
  Your Eaton UPS might be operating in battery mode due to a couple of reasons. For 230V models, the input circuit protector might be open; in this case, save your work, turn off your equipment and the UPS, reduce the load, and then press the input circuit protector on the UPS rear panel. Alternatively, the batteries may need charging or servicing. Plug the UPS into a power outlet for 24 hours. If the alarm beeps after pressing the button, the battery may need replacement.

  If your Eaton UPS is about to automatically shut down, it's likely because the power requirements exceed the UPS capacity or the load is defective. Try removing some equipment from the UPS. If the issue persists, consider obtaining a UPS with a larger capacity.
