Battery
The Liebert
®
 GXT3
 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery 
design life, operate the UPS in an ambient temperature of 15°C to 25°C (59°F to 77°F). Optional 
external battery cabinets are available to extend battery run times. For run times, see Table 14.

Dynamic Bypass
The Liebert GXT3 provides an alternate path for utility power to the connected load in the unlikely 
event of a UPS malfunction. Should the UPS have an overload, overtemperature or any other UPS 
failure condition, the UPS automatically transfers the connected load to bypass. Bypass operation is 
indicated by an audible alarm and illuminated amber Bypass LED (other LEDs may be illuminated to 
indicate the diagnosed problem). To manually transfer the connected load from the inverter to bypass, 
press the Standby/Manual Bypass button once and hold it for about 2 seconds.
NOTE
The bypass power path does NOT protect the connected equipment from disturbances 
in the utility supply.
