  Johnathan CunninghamAug 6, 2025
  If the icon and are flashing, a warning code appears on the LCD, and the alarm beeps twice every second, it indicates that the Powervar UPS is overloaded. This may be because the UPS is genuinely overloaded or, after repetitive overloads, the UPS is locked in bypass mode. To resolve this, remove excess loads from the UPS output. If the UPS is in bypass mode, also shut down the UPS and restart it.

  If fault code 43 and the icon appear on the LCD display and the alarm beeps continuously, it means the UPS shut down automatically due to an output overload. To fix this, remove some of the load from the UPS output and restart the UPS.

  Jordan TurnerAug 21, 2025
  If the battery backup time is shorter than expected, it might be because the batteries are not fully charged. Charge the batteries for at least five hours and then check the capacity. If the problem persists, there may be a defect with the batteries.

Why Powervar ACDEF2000-11 has no warning when mains is normal?
- N
  Natasha ChenAug 31, 2025
  If there is no warning or fault indication and no alarm, even though the mains is normal, the AC input power cord may not be firmly connected to the input of the UPS or to the mains, or the AC input is connected to the UPS output. Ensure that the AC input power cord is firmly connected to both the input of the UPS and the mains. Also, plug the AC input power cord firmly into the AC input.
