About Your New PowerStack UPS
This Uninterruptible Power Supply (UPS) is designed to prevent blackouts, brownouts, sags and surges from reaching your computer and other valuable electronic equipment. This UPS also filters out small utility line fluctuations and isolates your equipment from large disturbances by internally disconnecting from the utility line, while supplying power from its internal batteries until the utility line returns to safe levels.
While running on battery, an internal alarm will sound (periodic beeps).
If the utility power does not return, the UPS will continue supplying power to the connected equipment until exhausted. A continuous beeping will sound two minutes before the UPS’s final low battery shutdown. If using a computer, you must manually save your files and power down before the UPS turns itself off.
