INTRODUCTION AND SYSTEM DESCRIPTION  
Congratulations on your choice of the Liebert UPStation GXT™ 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, which may interrupt computer operations, cause data loss, or even  
damage equipment. The UPStation GXT™ protects equipment from these  
disturbances.  
The UPStation GXT™, 208 VAC models comes in nominal power ratings of 1800  
or 2700 VA. Complete specifications appear near the end of this section.  
The UPStation GXT™ is a compact, “on-line” UPS.  
An “on-line” UPS  
continuously conditions and regulates its output voltage, whether the 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™ contains a light emitting diode (LED)  
display to indicate either “load percentage” or “battery capacity” depending upon  
the mode of operation. It also provides self diagnostics, a combination On/Alarm  
Silence/Manual Battery Test button, a combination Off/Bypass button, and two  
levels of alarms when the unit is operating on battery.  
The UPStation GXT™ has an interface port for communications between the  
UPS and a LAN server or other computer system. This port provides detailed  
operating information including voltages, currents, and alarm status to the host  
system when used in conjunction with Liebert SiteNet® software. SiteNet®  
software can also remotely control UPS operation.  
CAUTION: This equipment has been tested and complies with limits for a Class  
A digital device, pursuant to Subpart B of Part 15 of FCC rules. These limits  
provide reasonable protection against harmful interference when the equipment  
is operated in a commercial environment. This equipment generates, uses, and  
can radiate radio frequency energy. If it is not installed and used in accordance  
with the instruction manual, it may cause harmful interference to radio  
communications. Operation of this equipment in a residential area is likely to  
cause harmful interference, which the user must correct at his own expense.

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, and 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™.  
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-DC converter. In both modes of the 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 battery system. The battery system charges  
whenever the UPStation GXT™ is plugged in.  
DC TO DC CONVERTER  
The DC-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™ employs valve regulated, nonspillable, lead acid batteries.  
At typical room temperatures and with the UPS float charging, the battery system  
will last many years. Optional external battery cabinets are available to provide  
extended run times. For battery run times, refer to the Typical Battery Discharge  
Curves.  
DYNAMIC BYPASS  
The UPStation GXT™ 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, over temperature, or UPS failure condition, the UPS  
automatically transfers the connected load to bypass. Bypass operation is  
indicated by an alarm and an illuminated Bypass LED (other LED’s may be  
illuminated to indicate the diagnosed problem). To manually transfer the  
connected load from the inverter to bypass power, press the Off button once.  
NOTE: The bypass power path does NOT protect the connected equipment  
from disturbances on the utility supply.

battery capacity. Refer to the Typical Battery Discharge Curves to determine the  
approximate amount of back up time with respect to your connected load  
percentage.  
The UPStation GXT™ is equipped with automatic and remote battery test  
features. The automatic test occurs every 14 days if utility has not been  
interrupted (14 day timer resets if unit goes to battery). Should the battery fail  
this test, the fault indicator along with the A and C diagnostic LEDs will illuminate  
and an alarm will sound (refer to Troubleshooting Guide). The remote test  
feature functions with either SiteNet® 2 or SiteNet® SNMP Manager software  
and can remotely initiate the battery test.  
Fault Indicator (Red)  
The Fault indicator is illuminated if the UPS has detected a problem. Also, one or  
more of the load/battery level indicators may be illuminated (refer to  
Troubleshooting Guide).

NOTE: Setting output voltage to any other voltage than 208 VAC will  
automatically increase the 1800 VA UPS VA and Watt rating to 2000 VA/1400W  
and the 2700 VA UPS VA and Watt rating to 3000 VA/2100W.  
OPERATION  
NORMAL MODE OPERATION  
During normal operation, utility power provides energy to the UPS. The filters,  
the power factor conditioning 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 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 sound an alarm.  
The display template indicates the percentage of load on the UPS output. Figure  
1 displays approximately 51-75% loading.

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-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 2  
beeps every 5 seconds when battery runs low (approximately 2 minutes  
remaining). The AC Input LED will extinguish, and the Battery LED will illuminate  
to warn that a utility problem has occurred. Each load/battery level indicator  
represents a 20% capacity level. As capacity decreases, fewer indicators remain  
illuminated. Refer to the Troubleshooting Guide.  
For battery run times, refer to the Typical Battery Discharge Curves. 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.  
Figure 2 displays approximately 61-80% battery capacity remaining.  
BATTERY RECHARGE MODE  
Once utility power is restored, the UPS resumes normal operation. At this time,  
the Battery Charger begins recharging the battery.

LIMITED WARRANTY  
Liebert Corporation extends the following LIMITED WARRANTY to the  
purchaser and to its customer (collectively referred to as the "Purchaser"): the  
enclosed Uninterruptible Power System (UPS) and components are free from  
defects in materials and workmanship under normal use, service, and  
maintenance FOR A PERIOD OF TWO YEARS FROM THE DATE OF  
ORIGINAL PURCHASE from Liebert or the Liebert dealer or retailer. THE  
FOREGOING WARRANTY IS THE ONLY WARRANTY GIVEN AND NO  
OTHER WARANTY IS PROVIDED, EXPRESS OR IMPLIED, INCLUDING  
WITHOUT LIMITATION, MERCHANTABILITY OR FITNESS FOR  
A
PARTICULAR PURPOSE. Certain aspects of disclaimers are not applicable to  
consumer products acquired by individuals and used for personal, family, or  
household purposes (as distinguished from industrial or other purposes). Local  
laws may not allow limitations on how long an implied warranty lasts, so the  
above limitation may not apply to you. This warranty gives you specific legal  
rights, and you may have other rights which vary according to local law.  
Certain repairs or services are the responsibility of the Purchaser and the  
Purchaser is expected to pay for them. This warranty does not extend either to  
products with removed or altered serial numbers or to any losses or damages  
due to act of God or source external to the product, misuse, accident, abuse,  
neglect, negligence, unauthorized modification, alteration, or repair, use beyond  
rated capacity, or improper installation, maintenance, application or use,  
including, without limitation, use in a manner contrary to the accompanying  
instructions or applicable codes. WARNING: Warranty is void if the battery is  
allowed to discharge below the minimum battery cutoff point. To prevent such  
discharge DO NOT leave the unit power switch "ON" for more than two (2) days  
without AC power being supplied to the UPS. The battery must be recharged  
every four (4) to six (6) months when not in use.  
If the UPS fails to conform with the above warranty within the two year warranty  
period, Liebert will repair or replace the UPS, at Liebert's option. Repairs or  
replacements are warranted for the remainder of the original warranty period.  
Purchaser, to make a warranty claim, should call 1-800-222-5877 to obtain a  
Returned Goods Authorization number and shipping instructions. Return  
transportation costs to Liebert are the responsibility of the Purchaser.
