Emerson GXT2U User Manual

The DC-to-DC converter utilizes energy from the battery system and raises 

the DC voltage to the optimum operating voltage for the inverter. This allows 

the inverter to operate continuously at its optimum efficiency and voltage, 

thus increasing reliability.

The Liebert GXT2U utilizes valve-regulated, nonspillable lead acid batteries. 

To maintain battery design life, operate the UPS in an ambient temperature 

of 68°F to 77°F (20°C to 25°C). Optional external battery cabinets are 

available to extend battery run times.

The Liebert GXT2U 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 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 

button once.

NOTE
The bypass power path does NOT protect the connected equipment
