Introduction
3.0 INTRODUCTION
Congratulations on your choice of the Liebert UPStation GXT 2U™
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 UPStation
GXT 2U protects equipment from these disturbances.
The UPStation GXT 2U comes in nominal power ratings of 700, 1000,
1500, 2000 and 3000 VA. Complete model specifications appear at the
end of this manual (see 12.0 - Specifications).
The UPStation GXT 2U is a compact, “on-line” UPS. An on-line UPS
continuously conditions and regulates its output voltage, whether
mains 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 UPStation GXT 2U 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 UPStation GXT 2U 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. MultiLink software can also
remotely control UPS operation.

4.1 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 mains
line and keep the sensitive equipment protected.
4.2 Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the rectifier/power factor correction (PFC) circuit
converts mains 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 mains power is used as efficiently as possible by the UPS.
• The amount of distortion reflected on the mains is reduced.
This results in cleaner power being available to other devices in the
building not being protected by the UPStation GXT 2U.
4.3 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 mains 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.
5
Page 10
Major Components
4.4 Battery Charger
The battery charger utilizes energy from the mains 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.
4.5 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.
4.6 Battery
The UPStation GXT 2U utilizes valve-regulated, nonspillable, flame
retardant, 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.
4.7 Dynamic Bypass
The UPStation GXT 2U 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 on the mains supply.

mains power bypasses the
inverter and provides power
for the connected load.
CAUTION
!
Turning OFF the UPS while in bypass mode will result in loss
of output power.

Operating Instructions
7.3 Battery Mode Operation
Battery mode occurs in
event of an extreme input
voltage condition or complete mains failure. The
battery system supplies
power through the DC to
DC converter to the
inverter to generate power
for the connected load.
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 mains problem has occurred. Each battery level
indicator represents a 20% capacity level. As capacity decreases, fewer
indicators remain illuminated. Refer to 11.0 - Troubleshooting.
For approximate battery run times, refer to 13.0 - Battery Run
Times. These times are approximates based on resistive load and an
ambient temperature of 25°C (77°F). 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.

7.4 Battery Recharge Mode
Once mains power is restored, the UPS resumes normal operation. At
this time, the Battery Charger begins recharging.

8.0 COMMUNICATIONS
8.1 Communications Interface Port
The UPStation GXT 2U UPS has a standard DB-9 serial port female
connector located on the rear of the UPS unit. Several signals are provided on this port and are assigned as follows:
Pin Assignment Description
1 Low Battery (open collector)
2 UPS TxD (typical RS-232 levels)
3 UPS RxD (typical RS-232 levels)
4 Remote Shutdown (5-12VDC, 10-24 mA max); battery operation
5 Common
6 Remote Shutdown (short to pin 5); all modes of operation

Open
Emitter
8.2 Pins 4 & 5 - Remote Shutdown on Battery
This pin is functional only when the UPS is in battery mode. If the UPS
is being powered by the mains, Pin 4 will ignore any signal on this pin.
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.
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.
19
Page 24
Communications
If the mains 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.
8.3 Pins 5 & 6 - Any-Mode Shutdown
Pin 6 of the 9-pin communication connector is used for “Any-Mode
Shutdown” of the UPS output. This control input may be used in special applications to disable the UPS output power—both Inverter and
Bypass.
The Options tab allows the behavior of the Any-Mode Shutdown feature to be modified. When the program opens, or the REFRESH button is pressed, the UPS setting is read by the configuration program
and displayed.
8.3.1 Auto-Enable Output
WARNING
!
Note that when this option is selected and the UPS output is
disabled using Pin 6, the UPS output can turn on
automatically and without warning if the Pin 6 connection is
changed.
8.3.2 Pin 6 Logic
WARNING
!
DO NOT CHANGE THIS OPTION from the factory default
setting unless you are ready to install a normally-closed
connection between Pins 5 & 6. This connection must be
maintained to use the UPS or to use the configuration
program again, including the ability to change the UPS
setting back to the default setting using the configuration
program via a serial communication link.
If version 1.6 (or later) is used with an earlier GXT 2U model (with an
earlier UPS firmware version), the Any-Mode Shutdown features cannot be changed.
If the configuration program is used with an earlier UPS model (with
an earlier UPS firmware version) that does not support the modification of these settings, the Options tab will display a reminder of the
factory default settings. These cannot be changed.

Communications
8.4 UPS Intelligent Communications
The UPStation GXT 2U is equipped with an Intellislot® port to provide advanced communication and monitoring options.
Liebert’s MultiLink software continually monitors the UPS and can
shut down your computer or server in the event of an extended power
failure.
MultiLink can also be configured for use without the serial cable when
the Intellislot SNMP/Web card is installed in the UPS. Additionally,
MultiLink can be configured to coordinate shutdown across the network with other computers running MultiLink when you purchase a
MultiLink License Kit. For more information about the Intellislot
SNMP/Web Card and MultiLink License Kits, visit our Web site
(www.liebert.com) or contact your local dealer or Liebert representative.
Several option cards are available for use in the Intellislot port of the
UPStation GXT 2U. The Intellislot SNMP/Web Card provides SNMP
and Web-based monitoring and control of the UPS across the network.
The Intellislot MultiPort 4 Card allows you to install MultiLink software on four computers and coordinate shutdown in the event of a
power failure.
The Intellislot Relay Card provides dry contact relay outputs for custom-wired applications and delivers support for built-in shutdown for
AS/400 systems.
CAUTION
!
To maintain safety (SELV) barriers and for electromagnetic
compatibility, signal cables should be segregated and run
separate from all other power cables, where applicable.

Configuration Program
9.0 CONFIGURATION PROGRAM
This is a new feature included with the new UPStation GXT 2U line. Several UPS settings that were previously not available or required custom
manufacturing may now be modified using this program. For most users,
the factory default settings will be adequate. This manual illustrates the
features available for modification, as well as the factory default setting.
NOTE
The UPS must be turned off—and not powering connected equipment—before you make any changes to configuration settings.
While the UPS is in Normal Mode operation, press the OFF
button once to put the UPS into Bypass Mode.
Once the UPS is in Bypass Mode operation, press and release
the OFF button two distinct times (for about a second each
time) to turn off the UPS.
9.1 GXT 2U Configuration Program Abilities
• Select one of five output voltages to match voltages found around
the world.
• Enable/Disable Auto-Restart.
• Select frequency converter operation with a fixed output frequency
of 50 or 60 Hz.

Maintenance
10.0 MAINTENANCE
The UPStation GXT 2U requires very little maintenance. The batteries are valve-regulated, nonspillable, flame retardant, lead acid, and
should be kept charged to obtain their designed life. The UPS continuously charges the batteries when connected to the mains supply.
When storing the UPS for any length of time, it is recommended to
plug the UPS in for at least 24 hours every four to six months to
ensure full recharge of the batteries.
The UPStation GXT 2U is designed to allow the user to safely replace
the internal batteries. Read the safety cautions before proceeding.
Contact your local dealer or Liebert representative to obtain the
appropriate replacement battery kit part number and pricing.
