Emerson 000-VA 用户手册

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 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 11.

The Liebert GXT3 provides an alternate path for mains 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
