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 subject 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 operation. 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, flammable 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 DISPOSAL 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 appliance 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.

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 installation and maintenance (applicable to a UPS and a remote battery supply not having a
grounded supply circuit).

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 equipment 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 indicate 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 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’s Multi-
™
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 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 Liebert GXT2-10000RT208.
3.3 Inverter
G
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.
3.4 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.

PRODU C T
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 optimum efficiency and voltage, thus increasing reliability.
3.6 Battery
The Liebert GXT2-10000RT208 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 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 illuminated 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.
