parts except the internal battery pack. The Liebert GXT3-10000RT208 and the Liebert GXT3-8000RT208 contain no userserviceable parts except the internal battery pack and the Power Module. The UPS On/Off push buttons do not electrically
isolate internal parts. Under no circumstances attempt to gain access internally due to the 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 the
UPS performance alters in use. Refer all faults to your dealer.
Servicing of batteries should be performed or supervised by personnel knowledgeable of batteries and the required
precautions. Keep unauthorized personnel away from the batteries. Keep unauthorized personnel away from the batteries.
Proper disposal of batteries is required. Refer to your local laws and regulations for disposal requirements.
Never block or insert any object into the ventilation holes or other openings.
DO NOT CONNECT equipment that could overload the UPS or demand DC current from the UPS, for example: electric
drills, vacuum cleaners, laser printers, hair dryers or any appliance using half-wave rectification.
Storing magnetic media on top of the UPS may result in data loss or corruption.
Turn Off and isolate the UPS before cleaning it. Use only a soft cloth, never liquid or aerosol cleaners.

1 INTRODUCTION
FOR HISTORICAL USE ONLY
Congratulations on your choice of the Liebert GXT3 uninterruptible power system (UPS). The Liebert GXT3 comes in
nominal power ratings of 5000VA, 6000VA, 8000VA 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 GXT3 protects equipment from these disturbances.
The Liebert GXT3 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 GXT3 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/Manual Battery Test button, a
Standby/Manual Bypass button and a configuration program.
The Liebert GXT3 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 SYSTEM DESCRIPTION
FOR HISTORICAL USE ONLY
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 GXT3.
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 GXT3 is connected to utility 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.
Vertiv| Liebert® GXT3 ™ Installer/User Guide | 10
2.6 Battery
FOR HISTORICAL USE ONLY
The Liebert GXT3 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 12.8 on page63.
2.7 Dynamic Bypass
The Liebert GXT3 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. Bypass operation is indicated by an audible alarm and illuminated amber Bypass
LED (other LEDs may be illuminated to indicate the diagnosed problem). To manually transfer the connected load from the
inverter to bypass, press the Standby/Manual Bypass button once and hold it for about 2 seconds.
NOTE: The bypass power path does NOT protect the connected equipment from disturbances in the utility supply.
