2.0 INTRODUCTION AND SYSTEM DESCRIPTION
Congratulations on your choice of the Liebert UPStation GXT2-6000RT208 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 UPStation GXT2-6000RT208 protects equipment
from these disturbances.
The UPStation GXT2-6000RT208 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 GXT2-6000RT208 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 UPStation GXT2-6000RT208 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
MultiLink™ software. 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 UPStation GXT2-6000RT208.
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 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 UPStation GXT2-6000RT208
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 optimum efficiency and voltage, thus increasing reliability.
3.6 Battery
The UPStation GXT2-6000RT208 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 GXT2-6000RT208 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.

6.0 INSTALLATION AND CONFIGURATION
This section includes instructions on how to install, configure and perform initial electrical checks of
your UPS installation.
DO NOT attempt to start the UPS, turn on any circuit breaker or energize the input power until
instructed to do so in 7.0 - Initial Startup and Electrical Checks.
Visually inspect the UPS for freight damage. Report damage to the carrier and your local dealer or
Liebert representative.
CAUTION
!
The UPS is heavy (see 14.0 - Specifications). Take proper precautions when lifting or
moving it.
