APC POWERCHUTE SOFTWARE
If you'd like to have more control over your APC UPS you can download the Powerchute software from their official website.
From the monitor system tab, you can check the performance of the UPS, current status, perform a self-test and check for energy savings.
Inside the configuration tab you have the ability to enable/disable notifications, send power quality information back to APC, set the UPS running time for your system, change the sensitivity of the UPS (i do recommend setting this to high if the electrical grid is not the best) and finally you can set the voltage range manually.
