Emerson GXT2U User Manual

The Liebert GXT2U requires very little maintenance. The batteries are valve-

regulated, nonspillable, lead acid and should be kept charged to obtain their 

designed life. The UPS continuously charges the batteries when connected to 

the utility supply.
When storing the UPS for any length of time, it is recommended to plug the 

UPS in for at least 24 hours every four to six months to ensure full recharge of 

the batteries.
The Liebert GXT2U is designed to allow the user to safely replace the internal 

batteries. Read the safety cautions before proceeding. Contact your local 

dealer or Liebert representative to obtain the appropriate replacement battery 

kit part number and pricing.

A battery can present a risk of electrical shock and high short 

circuit current. The following precautions should be observed before 

replacing the batteries:
• Remove rings, watches, or other metal objects.
• Use a Phillips (crosshead) screwdriver with insulated grips.
• Do not lay tools or other metal objects on top of the batteries.
• If the battery replacement kit is damaged in any way or shows 

signs of leakage, contact your local dealer or Liebert representa-
tive immediately. 

• Do not dispose of batteries in a fire. The batteries may explode.
