Configuration Program

8.9Battery Tab

Factory default settings illustrated.

The boxes above show options available in the drop-down menus.

The Liebert GXT2-10000RT208 automatically detects external battery

cabinets when they are connected. Use the Battery Cabinets Number selection box to select non-Liebert battery cabinets when used with the UPS.

8.9.1Low Battery Time Warning

The UPS will estimate remaining operating time when on batteries. A low battery alarm is activated if the estimated time reaches the Low Battery Time. This may be changed to any value from 2 to 30 minutes.

8.9.2Auto Battery Test Time

The UPS performs an automated battery test periodically, if enabled. The user may also set the UPS to test at intervals of 7, 14, 21, and 28 days.

8.9.3Battery Cabinets Number

If additional batteries are attached to the UPS, accurate battery run time estimates are possible if the battery number and type of batteries are entered here. The new UPS models are designed to operate with up to four external battery packs or four long run time (LRT) battery packs (not currently avail- able).

8.9.4Auto Battery Test

In some applications it may be preferable to disable the automated, periodic battery test. Click on the box to remove the check mark and disable the periodic battery test.

8.9.5Auto Restart

The UPS will provide computer grade power during power outages. If input power is unavailable for an extended time, the UPS will shut down when batteries are depleted, or a shutdown signal is sent by the computer operating system to limit battery depletion (serial data or contact closure). If Auto Restart is enabled (check mark in box), the UPS will restart when input power is restored. If the UPS turns off power to the load for any other reason, manual restart is required (See 8.7 - Options Tab for exceptions). Click on the box to remove the check mark and disable Auto Restart.
