IMPORTANT SAFETY INSTRUCTIONS
WARNING
!
Opening or removing the cover may expose you to lethal voltages within this unit even when
it is apparently not operating and the input wiring is disconnected from the electrical source.
Observe all cautions and warnings in this manual. Failure to do so may result in serious
injury or death. Refer all UPS and battery service to qualified service personnel. Do not
attempt to service this product yourself. Never work alone.
SAVE THESE INSTRUCTIONS
This manual contains important safety instructions. Read all safety, installation and operating
instructions before operating the Uninterruptible Power System (UPS). Adhere to all warnings on the
unit and in this manual. Follow all operating and user instructions. Individuals without previous
training can install and operate this equipment.
It is not intended for use with life support and other designated critical devices. Maximum load must
not exceed that shown on the UPS rating label. The UPS is designed for data processing equipment. If
uncertain, consult your local dealer or Liebert representative.
This UPS is designed for use on a properly grounded (earthed), 100/200, 110/220, 115/230, 120/208,
120/240 or 127/220 VAC, 50 Hz or 60 Hz supply. The factory default setting is 120/208 VAC, 60 Hz.
Installation instructions and warning notices are located in this manual.
This UPS is only for use with a four-wire input (L1, L2, N, G).
This UPS MAY NOT be used with a three-wire, single-phase utility source (L1, N, G).
ELECTROMAGNETIC COMPATIBILITY—The Liebert GXT2-10000RT208 Series complies with
the limits for a CLASS A DIGITAL DEVICE, PURSUANT TO Part 15 of FCC rules. Operation is sub-
ject to the following two conditions: (1) This device may not cause harmful interference and (2) this
device must accept any interference received, including interference that may cause undesired opera-
tion. Operating this device in a residential area is likely to cause harmful interference that users
must correct at their own expense.
Operate the UPS in an indoor environment only in an ambient temperature range of 32°F to +104°F
(0°C to +40°C). Install it in a clean environment, free from conductive contaminants, moisture, flam-
mable liquids, gases and corrosive substances.
This UPS contains no user serviceable parts except the internal battery pack. The Off/Bypass push
button does not electrically isolate internal parts. Under no circumstances attempt to gain access
internally other than to replace the batteries due to risk of electric shock or burn. Do not continue to
use the UPS if the front panel indications are not in accordance with these operating instructions or if
the UPS performance alters in use. Refer all faults to your local dealer, Liebert representative or the
Liebert Worldwide Support Group.
Servicing of batteries should be performed or supervised by personnel knowledgeable of batteries and
the required precautions. Keep unauthorized personnel away from the batteries. PROPER DIS-
POSAL OF BATTERIES IS REQUIRED. REFER TO YOUR LOCAL LAWS AND REGULATIONS
FOR BATTERY DISPOSAL REQUIREMENTS.
Never block or insert any object into the ventilation holes or other openings of the UPS.
DO NOT CONNECT equipment that could overload the UPS or demand half-wave rectification from
the UPS, for example: electric drills, vacuum cleaners, laser printers, hair dryers or any other appli-
ance using half-wave rectification.
Storing magnetic media on top of the UPS may result in data loss or corruption.
Turn the UPS off and isolate the UPS before cleaning; use only a soft cloth, never liquid or aerosol
cleaners. Keep the front and rear vents free of dust accumulation that could restrict airflow.

When replacing batteries, replace with the same Liebert authorized replacement battery kits. When
replacing the power module, replace it with the same Liebert authorized replacement power module
kit.
CAUTION
!
Do not dispose of battery or batteries in a fire. The battery may explode.
Do not open or mutilate the battery or batteries. Released electrolyte is harmful to skin and
eyes. It is toxic.
CAUTION
!
A battery can present a risk of electrical shock and high short circuit current. The following
precautions should be observed when working on batteries:
• Remove watches, rings and other metal objects.
• Use tools with insulated handles.
• Wear rubber gloves and boots.
• Do not lay tools or metal parts on top of batteries.
• Disconnect charging source prior to connecting or disconnecting battery terminals.
• Determine if the battery is inadvertently grounded. If inadvertently grounded, remove
source of ground. Contact with any part of a grounded battery can result in electrical shock.
The likelihood of such shock will be reduced if such grounds are removed during installa-
tion and maintenance (applicable to a UPS and a remote battery supply not having a
grounded supply circuit).

Introduction and System Description
2.0 INTRODUCTION AND SYSTEM DESCRIPTION
Congratulations on your choice of the Liebert GXT2-10000RT208 Uninterruptible Power Supply
(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 is
subject to voltage sags, spikes or complete power failure that may interrupt computer operations,
cause data loss or even damage equipment. The Liebert GXT2-10000RT208 protects equipment from
these disturbances.
The Liebert GXT2-10000RT208 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 equip-
ment with clean sinewave power. Sensitive electronic equipment operates best from sinewave power.
For ease of use, the Liebert GXT2-10000RT208 features a light-emitting diode (LED) display to indi-
cate both load percentage and battery capacity. It also provides self-diagnostic tests, a combination
ON/Alarm Silence/Battery Test button, a Standby button, user configurable program and two levels
of alarms when the unit is operating on battery.
The Liebert GXT2-10000RT208 has an interface port for communication between the UPS and a net-
work 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’s Multi-
™
Link software. Liebert MultiLink software can also control UPS operation remotely.

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 util-
ity 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 GXT2-10000RT208.
3.3
3.4
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 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 GXT2-10000RT208
is plugged in, even when the UPS is not turned on.

3.7
DC to DC Converter
The DC-to-DC converter utilizes energy from the battery system and raises the DC voltage to the opti-
mum operating voltage for the inverter. This allows the inverter to operate continuously at its opti-
mum efficiency and voltage, thus increasing reliability.
Battery
The Liebert GXT2-10000RT208 utilizes valve-regulated, nonspillable, flame retardant, lead acid bat-
teries. 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.
Static Bypass
The Liebert GXT2-10000RT208 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 indicator (other indicators may be illu-
minated to indicate the diagnosed problem).
The user may manually transfer the connected load from the inverter to bypass by pressing the
Standby button once.
NOTE
The bypass power path does NOT protect the connected equipment from disturbances
on the utility supply.

Initial Startup and Electrical Checks
7.0 INITIAL STARTUP AND ELECTRICAL CHECKS
Initial Startup and the Configuration Program—The UPS ships with a default 120 VAC L-N
setting. This is also the most robust setting in that it can operate with either input phase angle (120
or 180 degrees). Perform initial system checks first. If the UPS configuration needs to be modified for
your application, then go to the next section to review use of the configuration program. Some config-
uration changes require that the UPS be in the OFF mode while powered from the utility. Therefore,
the installer must confirm that the UPS input has been properly wired. After re-configuring your
UPS, the UPS may be put into service with the intended loads.

Configuration Program
8.0 CONFIGURATION PROGRAM
The final step of installation may require custom configuration of your UPS using the enclosed config-
uration program. Some configuration settings may be changed only while the UPS is off. These should
be set before the UPS is put into full time service powering the critical load.
For most users operating with 120VAC L-N, the factory default settings will be adequate. This section
illustrates the features available for modification, as well as the factory default setting.
The factory default L-N setting is 120 VAC. When first powered by the AC input, the UPS will auto-
sense the utility phase angle between L1 and L2, setting the UPS to operate as either a 120/208 VAC
system (120 degrees, leading or lagging) or a 120/240 VAC system (180 degrees).
If your application requires that the L1-N, L2-N voltages be set at 100, 110, 115 or 127VAC, the corre-
sponding phase angle between L1 and L2 is restricted. The VAC settings of 100, 110 and 115 may
work only with a phase angle of 180 degrees. A VAC setting of 127 VAC will work only with a phase
angle of 120 degrees (leading or lagging).
To confirm the phase angle of the utility input, measure the L1-N, L2-N and L1-L2 VAC of the utility
input that is intended for the UPS. If the measured L1-L2 voltage is equal to the average L-N voltage
times 2.0, then the phase angle is 180 degrees and the L-N VAC may be set at 100, 110, 115 or 120
VAC. The nominal L1-L2 voltages for these four settings will be 200, 220, 230 or 240 VAC, respec-
tively.
If the measured L1-L2 voltage is equal to the average L-N voltage times 1.73, then the phase angle is
120 degrees and the L-N VAC may be set at either 120 or 127 VAC. The nominal L1-L2 voltages for
these two settings will be 208 or 220 VAC, respectively.
Selecting an L-N nominal voltage that is not compatible with the L1-L2 phase angle detected by the
UPS when AC input is applied will result in a fault alarm and the UPS will not operate from utility
power.

Configuration Program—Installation
An easy-to-use installation program streamlines the installation of the configuration program. If you
have a previous version of this configuration program installed, Liebert recommends uninstalling it
by using its Uninstall program before installing this updated version.
1. Use the Windows Explorer to find and open the Lbt_gxt2-2.1.exe installation program.
2. When the installation program begins, you see the presetup window, shown below.
3. This will open the main installation screen. Click
NEXT to continue with the installation screens.
Liebert recommends using the default installation
options, but users may modify the standard entries.
The installation program will also install an uninstaller
program along with the UPS configuration program.
8.4
Establishing Communication Link with the
UPS
Only use the serial communication cable supplied with
the configuration program.
NOTE
If an accessory communication card has been installed in the Liebert IntelliSlot port in the
UPS, the option card must be removed while using the configuration program.
Use the serial communication cable to connect COM1 or COM2 of the host computer to the DB-9 com-
munication port on the rear of the UPS. If the COM port of the host computer only has a DB-25 pin
connector, a DB-25-to-DB-9 adapter must be added.
The program may be used while the UPS is On to read settings, confirm the current settings and
change some settings. The UPS must be Off and powered by the AC utility when using the configura-
tion program to change some specified UPS settings.
On-screen prompts will advise the user if the UPS must be turned Off for a configuration program
operation.
Select Lbt_gxt2.exe from the
program group to start the con-
figuration program. The pro-
gram will search COM1 &
COM2 for a properly connected
UPS. When the UPS is found,
the opening program window
will display the UPS model.
If the configuration program
fails in its attempt to read data
from a UPS, this error message
will be displayed. The program
must communicate with the
UPS when it first opens, when a new tab is opened, and when the REFRESH, APPLY or OK buttons
are pressed.

If this message is displayed check the following items:
• Verify that the serial communication cable is connected properly.
• Verify that the COM port being used is designated COM1 or COM2.
• Verify that the UPS is either in Inverter mode, Bypass mode, Battery mode, or Off with AC power
available at the input (AC Input LED on). In each case, the rear fan will be running.
• Verify that the COM port is not in use by other UPS communication software (or non-UPS soft-
ware). If Liebert MultiLink UPS software is installed on the computer, the Liebert MultiLink ser-
vice must be stopped to free the COM port. Liebert MultiLink typically restarts automatically
whenever the computer restarts.
• The Liebert IntelliSlot port in the UPS CANNOT be in use by an internal, optional communica-
tion card in the UPS card slot. Remove the option card.
• The program is connected to a UPS that was not designed for this program.

UPS Tab
When the program starts, the following window will open displaying the UPS model along with the
current UPS settings. This information can be refreshed at any time using the REFRESH button.
These illustrations show the factory default settings for 120VAC UPS at the left, and output L-N volt-
ages available to select at the right.
8.6.1 Output Voltage
The Output Voltage displayed is the nominal input/output voltage. This is not a voltmeter and will
display the nominal voltage whether the UPS is On or Off. The drop down box will show the alternate
L-N voltages available. Select the voltage that matches the nominal utility in your location.
Output Voltage Selection Notes
For the Liebert GXT2 dual inverter models, this sets the L1-N and the L2-N nominal voltage. The
L1-L2 voltage depends upon the phase angle of the input utility and is auto-detected when power is
first applied.
For the Liebert GXT2 230V single inverter model, only those voltages supported by the UPS will be
displayed.
8.6.2 L-N Reverse Detection—120V UPS Models Only
Proper wiring of the receptacle powering the UPS is critical for safety, EMI suppression, and surge
suppression. The UPS checks the outlet when first plugged in. If the Line-Neutral is reversed or the
ground is missing, the UPS will not start. If a problem is detected after the UPS is started, the UPS
will continue to operate, but the AC INPUT LED will flash. In some unique applications the user may
wish to disable this alarm. Except for special situations, improperly wired receptacles should be
immediately repaired before the UPS is put into service. Click on the box to remove the check mark
and disable this alarm.

8.6.3 Frequency Selection
The UPS is normally designed for 50Hz or 60Hz operation. The factory default corresponds to the
model. All models are capable of being used as 50Hz or 60Hz systems. The UPS will Auto-sense the
utility frequency when first plugged in and set the nominal frequency to match. Therefore, for all nor-
mal use the Auto Sense button should be selected.
Some special applications require that the UPS be used as a frequency converter. Frequency Con-
verter 50Hz mode will provide 50Hz UPS output from 60Hz commercial power. Frequency converter
60Hz mode will provide 50Hz UPS output from 60Hz commercial power.
Note that frequency converter operation disables the Bypass. If, for any reason, the UPS inverter is
unable to power the load, the alternate bypass to utility power will not be available and power will be
removed from any load.
8.7
Options Tab
Computer users may choose to use versatile
computer shutdown software that communi-
cates with the UPS via a serial communication
cable. The Options Tab should not be used to
modify the UPS functions for such applica-
tions.
For some industrial applications and special
computer applications, the UPS may be moni-
tored and controlled using external voltages
and relay contact signals. The Options tab
expands the UPS versatility for such applica-
tions.
Refer to your UPS manual for a description of
the nine-pin communication connector on the
rear of the UPS. Pin 6 of the nine-pin commu-
nication connector is used for “Any Mode Shut-
down” 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 but-
ton is pressed, the UPS setting is read by the

Modes of Operation
10.0 MODES OF OPERATION
10.1 Normal Mode Operation
During normal operation, utility power provides energy to
the UPS. The filters, power factor correction circuit and the
inverter process this power to provide computer grade
power to connected loads. The UPS maintains the batteries
in a fully charged state. The four green Load Level indica-
tors display an approximate level of load in 25% increments.
If the UPS becomes loaded beyond full rating, the fifth
(amber) indicator will illuminate and the UPS will sound an
audible alarm. The display template indicates the percent-
age of load (see example at right) on the UPS output.
Normal Mode Operation
Batteries at 100% charge
L1 Load at 10%, L2 Load at 90%
10.2 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. 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 indicator will extinguish and
the Battery indicator will illuminate to warn that a utility
problem has occurred. Each Battery Level indicator repre-
sents a 20% capacity level. As capacity decreases, fewer
indicators remain illuminated. Refer to 13.0 - Trouble-
shooting. For approximate battery run times, refer to
Table 6 - Battery run times. These times are approximate

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.
10.3 Battery Recharge Operation
Once utility power is restored, the UPS resumes normal operation. At this time, the Battery Charger

11.2 Pin 4 - 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.
11.3 UPS Intelligent Communications
®
The Liebert GXT2-10000RT208 is equipped with a Liebert IntelliSlot port to provide advanced com-
munication 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.
Liebert MultiLink can also be configured for use without the serial cable when the Liebert IntelliSlot
SNMP/OCWEBCARD is installed in the UPS. Additionally, Liebert MultiLink can be configured to
coordinate shutdown across the network with other computers running Liebert MultiLink when you
purchase a Liebert MultiLink License Kit. For more information about the Liebert IntelliSlot SNMP/
your local dealer or Liebert representative.
Several option cards are available for use in the Liebert IntelliSlot port of the Liebert
GXT2-10000RT208. The Liebert Intellislot SNMP/OCWEBCARD provides SNMP and Web-based
monitoring and control of the UPS across the network.
The Liebert IntelliSlot MultiPort 4 Card allows you to install Liebert MultiLink software on four com-
puters and coordinate shutdown in the event of a power failure.
The Liebert IntelliSlot Relay Card provides dry contact relay outputs for custom wired applications
and delivers support for built-in shutdown for AS/400 systems.

Maintenance
12.0 MAINTENANCE
The Liebert GXT2-10000RT208 requires very little maintenance. The batteries are valve-regulated,
non-spillable, flame retardant, lead acid and should be kept charged to obtain their design life. The
UPS continuously charges the batteries when connected to the utility supply.
When storing the UPS for any length of time, it is essential to plug the UPS in for at least 24 hours
every four to six months to ensure full recharge of the batteries. Failure to recharge the batteries peri-
odically will permanently degrade battery capacity.
The Liebert GXT2-10000RT208 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.
12.1 Battery Replacement
CAUTION
!
A battery can present a risk of electrical shock and high short circuit current. The following
precautions should be observed before replacing the batteries:
• Remove rings, watches and other metal objects.
• Use a Phillips (crosshead) screwdriver with insulated grips.
• Do not lay tools or other metal objects on top of the batteries.
• If the battery replacement kit is damaged in any way or shows signs of leakage, contact
your local dealer or Liebert representative immediately.
• Do not dispose of batteries in a fire. The batteries may explode.
12.1.1 Internal Battery Replacement Procedures
Both battery packs should be replaced at the same time.
1. Gently remove the front center plastic bezel
cover from the UPS by pulling forward.

Troubleshooting
13.1 Auto-Learning Battery Run Times
As batteries age, the estimated run times may become less accurate. The Liebert GXT2-10000RT208
is programmed to “learn” from a full battery discharge and modify the estimated run time for the
measured battery capacity. This can improve accuracy and compensate for aging batteries or batter-
ies that operate at different ambient temperatures.
The UPS will update the anticipated run time calculation only under certain conditions.
• The UPS must have a steady load that is greater than 20%.
• The UPS must be at 100% charge at the start of a battery discharge.
• The battery discharge must continue uninterrupted until the batteries reach their end-of-dis-
charge voltage.
If all conditions are not met, the run time calculation will not be modified.
If the configuration program is used to change the number of battery cabinets, then the values in
Table 6 will be restored. This will override any value that is automatically learned.
