Liebert GXT2-6000RTL630 user manual DC-to-DC Converter, Battery, Dynamic Bypass

System Description

2.5DC-to-DC Converter

The DC to DC converter utilizes energy from the battery system and raises the DC voltage to the opti- mum operating voltage for the inverter. This allows the inverter to operate continuously at its opti- mum efficiency and voltage, thus increasing reliability.

2.6Battery

The GXT2-6000RTL630 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain bat- tery 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.

2.7Dynamic Bypass

The GXT2-6000RTL630 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 from disturbances in the utility supply.
