BATTERY CHARGER
The battery charger utilizes energy from the utility power and precisely
regulates it to continuously “float charge” the batteries. The batteries are
being charged whenever the UPStation GXT 2U is plugged in, even when
the UPS is not turned on.
DC TO DC CONVERTER
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.
BATTERY
The UPStation GXT 2U utilizes valve-regulated, nonspillable, flame retar-
dant, 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 exter-
nal battery cabinets are available to extend battery run times.
DYNAMIC BYPASS
The UPStation GXT 2U 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 opera-
tion 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 on the utility supply.
