DC-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.

Battery

The UPStation GXT2 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery
design life, operate the UPS
in an ambient temperature of 20°C to 25°C (68°F to 77°F). Optional external battery cabinets are
available to extend battery run times.
2.7

Dynamic Bypass

The UPStation GXT2 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 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 mains supply.
