ON BATTERY OPERATION
The UPS switches to battery operation automatically and an internal alarm sounds (periodic beeps) if the utility power fails. Press the ON button (front panel) to silence the UPS alarm until low battery (for the current outage only). You can change the audible indicator if you are using PowerChute software. If the utility power does not return, the UPS continues to supply power to the connected equipment until exhausted. The UPS will begin to beep continuously approximately two minutes before final low battery shutdown by default. If you are using a computer, you must manually save your files and power down before the UPS turns off, unless you are using PowerChute interface software that provides automatic, unattended shutdown.
UPS battery life differs based on usage and environment. It is recommended that the battery pack be changed once every three years. See the
