Chapter 1 Introduction 1
Chapter 1 Introduction
Congratulations on your choice of the Liebert® GXT4™ uninterruptible power system (UPS). The Liebert GXT4
comes in nominal power ratings of 5000VA, 6000VA and 10,000VA. It is designed to provide conditioned power to
microcomputers and other sensitive electronic equipment.
When it is generated, alternating current is clean and stable. However, during transmission and distribution it is
subject to voltage sags, spikes and complete power failure that may interrupt computer operations, cause data loss
and even damage equipment. The Liebert GXT4 protects equipment from these disturbances.
The Liebert GXT4 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.
The Liebert GXT4 features a multicolor LCD display to indicate load percentage, input/output voltage and current,
runtime of battery and so on. It also provides self-diagnostic tests by visual configuration.
The Liebert GXT4 can be operated at high efficiency mode (Green Mode) which efficiency could up to 97%.
The Liebert GXT4 includes E models without rack slide kits for different requirement of user.
The Liebert GXT4 has a Liebert IntelliSlot® 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 MultiLink®. Liebert MultiLink can also remotely control UPS
operation.

2.1 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.
2.2 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®
GXT4™.
2.3 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.
2.4 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 GXT4 is connected to mains power.
2.5 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.

2.6 Battery
The Liebert® GXT4™ utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery design life,
operate the UPS in an ambient temperature of 15°C to 25°C (59°F to 77°F). Optional external battery cabinets are
available to extend battery run times. For run times, see Table 11-5.
2.7 Dynamic Bypass
The Liebert GXT4 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 any other UPS failure condition, the UPS
automatically transfers the connected load to bypass.
NOTE
The bypass power path does NOT protect the connected equipment from disturbances in the mains supply.
