What to do if the Liebert Adapt BX 6K UPS is beeping twice every second?
- J
  Jacqueline DavisAug 14, 2025
  If the Liebert UPS is overloaded, indicated by the icon flashing on the LCD and the alarm beeping twice every second, it means that the devices connected to the UPS are drawing more power than it can supply. This can also happen if the UPS is overloaded for a prolonged time, causing it to enter Bypass mode, where connected devices are powered directly from the mains. To resolve this: * Remove some of the connected devices to reduce the load on the UPS. * If the UPS is in Bypass mode due to repetitive overloads, first remove excess loads, then shut down the UPS and restart it.

  Brandi GarciaAug 17, 2025
  If the battery backup time of your Liebert UPS is shorter than expected, there are a couple of potential reasons. Either the batteries are not fully charged, or the batteries are defective. You can try charging the batteries for at least 7 hours to ensure they are fully charged and then check the capacity. If the issue continues, it may indicate a battery defect.

  If fault code 43 is displayed on your Liebert UPS, accompanied by a lit icon and continuous beeping, it indicates that the UPS has been overloaded for too long, resulting in a fault and automatic shutdown. To fix this, remove some of the connected devices to reduce the load on the UPS output and then restart it.

  If fault code 14 appears on the LCD display of your Liebert UPS, the icon is lit, and the alarm beeps continuously, it means that the UPS has automatically shut down because a short circuit has occurred on the UPS output. You should check the output wiring and the connected devices to see if they are in a short circuit status.

  If there is no display or alarm on the front panel of your Liebert UPS, even when the mains power is normal, it may indicate that the AC input power is not properly connected. Check to ensure that the input cable is firmly connected to the mains.
