System Description

3.5DC 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.

3.6Battery

The Liebert GXT2-10000RT208 utilizes valve-regulated, nonspillable, flame retardant, lead acid bat- teries. 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.

3.7Static Bypass

The Liebert GXT2-10000RT208 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 indicator (other indicators may be illu- minated to indicate the diagnosed problem).

The user may manually transfer the connected load from the inverter to bypass by pressing the Standby button once.

NOTE

The bypass power path does NOT protect the connected equipment from disturbances on the utility supply.
