Introduction
2.0
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 comes in nominal power ratings of 500, 700, 1000,
1500, 2000 and 3000 VA. 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
sinewave 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.

3.1
TRANSIENT VOLTAGE SURGE SUPPRESSION (TVSS)
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.
3.2
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.
3.3
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.

DISCONTINUED
PRODUCT
Major Components
3.4
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.
3.5
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.
3.6
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.
3.7
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.

BATTERY MODE OPERATION
Battery mode occurs in
event of an extreme input
voltage condition or complete utility failure. The
battery system supplies
power through the DC to
DC converter to the
inverter to generate power
for the connected load.
AC INPUT BATTERY UPS ON BYPASS
Battery Mode Operation at 80-61%
During battery mode an alarm sounds every 10 seconds. This will
change to two beeps every 5 seconds when the battery runs low
(approximately 2 minutes remaining, but this is user configurable).
The AC Input LED will extinguish, and the Battery LED will illuminate to warn that a utility problem has occurred. Each battery level
indicator represents a 20% capacity level. As capacity decreases, fewer
indicators remain illuminated. Refer to 10.0 - Troubleshooting.
For approximate battery run times, refer to 13.0 - Battery Run
Times. The times listed in these tables are approximate based on
resistive load and an ambient temperature of 77°F (25°C). To increase
this time, turn off non-essential pieces of equipment (such as idle computers and monitors) or add the optional external battery cabinet.
!
CAUTION
Turning OFF the UPS while in battery mode will result in loss
of output power.
If the UPS is manually turned OFF, it must be manually restarted
after utility power is restored.
If the UPS is turned OFF by a communication signal or because the
batteries are depleted, it will operate as selected in the configuration
program for Auto-Restart (see 8.1 - Liebert GXT2U Configuration
Program Abilities).

PINS 4 & 5 - REMOTE SHUTDOWN ON BATTERY
1. This pin is functional only when the UPS is in battery mode. If the
UPS is being powered by the utility, Pin 4 will ignore any signal
on this pin.
2. Pin 4 requires a 5-12 VDC signal to shutdown. This normally
comes form the serial port using Liebert’s contact closure cable. It
cannot be used with just a contact closure unless the relay is used
to switch a voltage source. A 5-12 VDC signal for 1.5 seconds or
greater is required to signal a shutdown. Signals for less than 1.5
seconds will be ignored. After Pin 4 receives a shutdown signal for
1.5 seconds, the command cannot be canceled.
3. A battery shutdown signal on Pin 4 will NOT cause an immediate
shutdown. A shutdown signal will start a 2-minute shutdown
timer. The timer cannot be stopped. After 2 minutes, the UPS will
shut down.
4. If the utility returns during the 2-minute timer countdown, the
shutdown timer will continue until the end of 2 minutes and the
UPS will turn OFF. The UPS must remain OFF for at least 10
seconds even if AC input power returns before the UPS turns
OFF. This serves to reset and restart the server.
Whether the UPS turns back ON when power is restored depends on
the auto-restart setting: enabled or disabled.
If the auto-restart is disabled, the UPS will not restart after performing the 2-minute shutdown delay.
