6.Unpack a new internal battery pack. Take care not to destroy the packing.

Compare the new and old internal battery packs to make sure they are the same type and model. If they are the same, proceed with Step 7; if they are different, stop and contact your local Emer- son representative or Emerson Channel Support.

7.Line up and slide in the new internal battery pack.

8.Repeat Steps 6 and 7 if replacing both battery packs. Each model has two battery packs

9.Reconnect the battery plugs and battery receptacles.

10.Gently push the battery wire into the UPS battery compartment.

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.

10.2Battery 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.

10.3Precautions

Although the Liebert GXT3 has been designed and manufactured to ensure personal safety, improper use can result in electrical shock or fire. To ensure safety, observe the following precautions:

•Turn Off and unplug the Liebert GXT3 before cleaning it.

•Wear rubber gloves and boots.

•Clean the UPS with a dry cloth. Do not use liquid or aerosol cleaners.

•Never block or insert any objects into the ventilation holes or other openings of the UPS.

•Do not place the Liebert GXT3 power cord where it might be damaged.
