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 is rated for 2700 VA, 1890 watts. Complete model
specifications appear at the end of this manual.
The UPStation GXT 2U 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 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.

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.
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 UPStation GXT 2U.
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.
5
Page 10
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 retardant, 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 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 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.

energy to the UPS. The utility
power bypasses the inverter
and provides power for the
Bypass Mode Operation at 26-50%
connected load.
The four green load level LEDs indicate an approximate level of load in
25% increments. If the UPS becomes loaded beyond full rating, the fifth
(amber) LED indicator will illuminate and the UPS will sound an audible
alarm. The display template indicates the percentage of load (26-50% of
load shown in the example above) on the UPS output.
CAUTION
!
Turning OFF the UPS while in bypass mode will result in
loss of output power.
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
AC INPUT BATTERY UPS ON BYPASS
Battery Mode Operation at 80-61%
DC to DC converter to the
inverter to generate power
for the connected load.
17
Page 22
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
Troubleshooting section.
For approximate battery run times, refer to the Battery Run Times charts
in this manual. These times are approximates 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.
BATTERY RECHARGE MODE
Once utility power is restored, the UPS resumes normal operation. At this
time, the Battery Charger begins recharging.

COMMUNICATIONS
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
7 Low Battery (open emitter)
8 Utility Fail (open emitter)
9 Utility Fail (open collector)

(+)
(-)
* Maximum voltage and current on pins 1, 7, 8, and 9 is 60VDC; 10.0 mA.
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.
19

Collecto
Open
Emitter
Page 24
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.
PINS 5 & 6 - ANY-MODE SHUTDOWN
1. 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.
2. 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.
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.
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.
20
Page 25
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.
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 customwired 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.
21
Page 26
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.
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.
• Set the Low Battery Warning alarm time from 2 to 30 minutes.
• Enable/Disable the Auto-Battery test.
• Set the Auto-Battery test to 7, 14, 21, or 28 days.
• Select the number of external battery cabinets connected to the
UPS to adjust the remaining run time calculations reported by Liebert software products.
• Modify the shutdown setting of DB-9 pin 6 (for information on pin
assignments, see Communications on page 19).
NOTE
This program is compatible with UPS models beginning with
“GXT2-”, as in “GXT2-2700RT208.” It is not compatible with
earlier versions of UPStation GXT UPS.
What You Will Need
In addition to the GXT 2U UPS, you will need the configuration program diskette and serial cable (beige or tan, 3-wire: GND, TX, RX; straight through
2-2, 3-3, 5-5) included in the UPS accessory box. The BLACK ML9P9S
CONTACT CLOSURE communication cable IS NOT compatible with the
configuration program. A Windows 95
®
, 98®, or NT® computer—desktop or
laptop—is also required to set up and run the configuration program.
22
Page 27
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 utility 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.
