Introduction  
2.0 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 opera-  
tions, 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 500, 700,  
1000, 1500, 2000 and 3000 VA. 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 util-  
ity 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 conjunc-  
tion 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 elec-  
tromagnetic 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 UPStation GXT 2U.  
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.

Major Components  
3.4  
BATTERY CHARGER  
The battery charger utilizes energy from the utility power and pre-  
cisely regulates it to continuously “float charge” the batteries. The bat-  
teries are being charged whenever the UPStation GXT 2U 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 opti-  
mum efficiency and voltage, thus increasing reliability.  
3.6  
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 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 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 diag-  
nosed 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.

Operating Instructions  
6.3  
BATTERY MODE OPERATION  
Battery mode occurs in  
event of an extreme input  
voltage condition or com-  
plete utility failure. The  
battery system supplies  
power through the DC to  
DC converter to the  
AC INPUT BATTERY UPS ON BYPASS  
inverter to generate power  
for the connected load.  
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 illumi-  
nate 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 com-  
puters 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.

Communications  
7.2  
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 perform-  
ing the 2-minute shutdown delay.

Communications  
7.3  
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.  
7.3.1 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.  
7.3.2 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 can-  
not be changed.  
If the configuration program is used with an earlier UPS model (with  
an earlier UPS firmware version) that does not support the modifica-  
tion 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 pro-  
vide 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 net-  
work 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 the Liebert Web  
site (www.liebert.com) or contact your local dealer or Liebert repre-  
sentative.  
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 shut-  
down for AS/400 systems.  
• The Intellislot USB Card provides communication using built-in

power management software available on Microsoft Windows  
2000/XP platforms.  
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.
