INTRODUCTION
Congratulations on your choice of the Liebert GXT2U™ Uninterruptible
Power System (UPS). It provides conditioned power to microcomputers and
other sensitive electronic equipment.
Upon generation, AC power is clean and stable. However, during transmission
and distribution it may be subject to voltage sags, spikes, or complete power
failure that may interrupt computer operations, cause data loss, or even
damage equipment. The Liebert GXT2U protects equipment from these
disturbances.
The Liebert GXT2U is rated for 2700 VA, 1890 watts. Complete model
specifications appear at the end of this manual.
The Liebert GXT2U is a compact, “on-line” UPS. An on-line UPS continuously
conditions and regulates its output voltage, whether utility power is present
or not. It supplies connected equipment with clean sine wave power. Sensitive
electronic equipment operates best from sinewave power.
For ease of use, the Liebert GXT2U features a light-emitting diode (LED)
display to indicate either load percentage or battery capacity depending upon
the mode of operation. It also provides self-diagnostic tests, a combination ON/
Alarm Silence/Manual Battery Test button, a Standby button, user
configurable program, and two levels of alarms when the unit is operating on
battery.
The Liebert GXT2U has an interface port for communication between the UPS
and a network server or other computer systems. This port provides detailed
operating information including voltages, currents, and alarm status to the
host system when used in conjunction with Liebert MultiLink™ software.
Liebert MultiLink software can also remotely control UPS operation.

MAJOR COMPONENTS
Transient Voltage Surge Suppression and EMI/RFI Filters
These UPS components provide surge protection and filter both
electromagnetic interference (EMI) and radio frequency interference (RFI).
They minimize any surges or interference present in the utility line and keep
the sensitive equipment protected.
Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the rectifier/power factor correction (PFC) circuit
converts utility AC power to regulated DC power for use by the inverter while
ensuring that the waveshape of the input current used by the UPS is near
ideal. Extracting this sinewave input current achieves two objectives:
• The utility power is used as efficiently as possible by the UPS.
• The amount of distortion reflected on the utility is reduced.
This results in cleaner power being available to other devices in the building
not being protected by the Liebert GXT2U.
Inverter
In normal operation, the inverter utilizes the DC output of the power factor
correction circuit and inverts it into precise, regulated sinewave AC power.
Upon a utility power failure, the inverter receives its required energy from the
battery through the DC to DC converter. In both modes of operation, the UPS
inverter is on-line and continuously generating clean, precise, regulated AC
output power.
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 Liebert GXT2U 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 Liebert GXT2U utilizes valve-regulated, nonspillable 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 external battery cabinets are
available to extend battery run times.
Dynamic Bypass
The Liebert GXT2U 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 on the utility supply.
