Channel Support.

11. Reattach the front battery door with the six screws.
12. Reattach the front plastic bezel cover to the UPS.
NOTE: The internal battery pack is hot-swappable. However, caution should be exercised because the load is
unprotected from disturbances and power failures during this procedure. Do not replace the battery while the UPS is
operating in Battery Mode. This will result in a loss of output power and will drop the connected load.
10.2 Battery Charging
The batteries are valve-regulated, nonspillable, lead acid and should be kept charged to attain their design life. The Liebert
GXT3 charges the batteries continuously when it is connected to the utility input power.
If the Liebert GXT3 will be stored for a long time, Emerson recommends connecting the UPS to input power for at least 24
hours every four to six months to ensure full recharge of the batteries.
