1.6.1 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 mains line and
keep the sensitive equipment protected.
Liebert® GXT4™ User Manual

Product Description
1.6.2 Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the rectifier/power factor correction (PFC) circuit converts mains 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 mains power is used as efficiently as possible by the UPS.
• The amount of distortion reflected on the mains is reduced.
This results in cleaner power being available to other devices in the building not being protected by the
Liebert GXT4.
1.6.3 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 mains 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.
1.6.4 Battery Charger
The battery charger utilizes energy from the mains 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.
1.6.5 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.
1.6.6 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
1.6.7 Internal Bypass
The Liebert GXT4 provides an alternate path for mains 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
1.6.8 Maintenance Bypass
The Liebert GXT4 provides a manual maintenance bypass in a removable section of the rear of the UPS.
This allows replacement of the UPS in the event of a UPS malfunction while keeping the connected
equipment powered with utility power.
NOTE
The bypass power path does NOT protect the connected equipment from disturbances in
the mains supply.

Liebert® GXT4™ User Manual
Product Description
1.7 Operating Mode
The UPS operation modes include the following: Mains (AC) Mode, Bypass Mode, Battery Mode, Battery
Recharge Mode, Active ECO Mode and Frequency Converter Mode.
Refer to 3.0 - Operation and Display Panel for details about the operating mode indicators and control
buttons.
1.7.1 Mains Mode
During Mains Mode, the mains provides input power to the Liebert GXT4. The filters, PFC circuit and
inverter process this power to provide high-quality sine wave power to connected loads. The UPS
maintains the batteries in a fully charged state.
1.7.2 Manual Bypass Mode
Manual Bypass Mode occurs when the unit is manually placed in internal bypass by navigating the LCD
menu to select 3 Control > 1 Turn On & Off > Turn UPS Bypass. Bypass operation is indicated by an
audible alarm and illuminated amber bypass indicator. (If other indicators are illuminated, refer to 7.0 -
Troubleshooting). During Bypass Mode, mains power bypasses the inverter and provides energy to the
connected load.
NOTICE
Risk of loss of power to the connected load. Can cause equipment damage.
Turning Off the UPS in Bypass Mode will result in loss of output power to the connected load.
1.7.3 Battery Mode
The Liebert GXT4 enters Battery Mode when mains power fails or is outside acceptable limits. The battery
system supplies power through the DC-to-DC converter to the inverter to generate clean AC power for the
connected loads.
When the Liebert GXT4 enters Battery Mode, the UPS sounds a half-second beep at 10-second intervals.
When approximately 2 minutes of run time remains, the beeps sound every 5 seconds to warn that the
battery is getting low (this Low Battery Warning is user-configurable).
In Battery Mode, the battery indicator will illuminate and the LCD will show the prompt utility power not
available.
Press either the Up or Down button once, then press the Enter button to clear the prompt and silence the
audible alarm. Once the alarm prompt has been acknowledged, the screen showing the estimated battery
For approximate battery run times, refer to Table 8-4.
NOTICE
Risk of loss of power to the connected load. Can cause equipment damage.
Turning Off the Liebert GXT4 when it is in Battery Mode will result in loss of output power to the
connected load.

All Liebert GXT4 models can operate in Active ECO Mode. In this mode, the connected equipment is
powered through the bypass path to increase efficiency, reducing the electrical costs.
Active ECO mode keeps the rectifier and inverter operating, allowing the inverter to remain synchronized
to bypass. This synchronization allows the transfer of the connected equipment to UPS inverter power
almost seamlessly if bypass power falls outside the user-set limits. Once bypass power returns within the
acceptable parameters, the UPS will return to Active ECO Mode operation.
The default setting is Active ECO Mode Off.

Liebert® GXT4™ User Manual
Installation
2.3 Preparation for Installation
2.3.1 Installation Environment
Install the Liebert GXT4 indoors in a controlled environment, where it cannot be accidentally turned Off.
Place it where air flows unrestricted around the unit. The installation location must be free of water,
flammable liquids, gases, corrosives and conductive contaminants. Maintain an ambient temperature
range of 0 to 32 - 104°F (0 – 40°C).
NOTE
UPS operation in sustained temperatures outside the range of 59° – 77°F (15 – 25°C)
reduces battery life.
Installation Clearances
Maintain a clearance of at least 100 mm (4 inches) in the front and rear of the Liebert GXT4. Do not
obstruct the air inlets on the front panel or rear panel of the UPS—blocking the air inlets reduces ventilation
and heat dissipation, shortening the service life of the Liebert GXT4.
2.4 Install the Main Cabinet
The Liebert GXT4 may be installed in either a tower configuration or in a rack, depending on available
space and use considerations. Determine the type of installation and follow the appropriate instructions in
2.4.1 Tower UPS Installation

Run times in this table are approximate. They are based on new, fully charged standard battery modules at a temperature of 77°F (25°C) with
100% resistive UPS loading. Run times listed above can vary by ±5% due to manufacturing variances of the individual batteries.
Using the configuration program or the LCD panel, the user may specify the number of external battery
cabinets attached to the UPS. The factory default is programmed for internal batteries only.
Table 8-8 shows the estimated run times at different loads.

Specifications
8.1 Auto-Learning Battery Run Times
As batteries age, the estimated run times may become less accurate. The Liebert GXT4 is programmed to
“learn” from a full battery discharge and modify the estimated run time for the measured battery capacity.
This can improve accuracy and compensate for aging batteries or batteries that operate at different
ambient temperatures.
The UPS will update the anticipated run time calculation only under certain conditions.
• The UPS must have a steady load that is greater than 20%.
• The UPS must be at 100% charge at the start of a battery discharge.
• The battery discharge must continue uninterrupted until the batteries reach their end-of-discharge
voltage.
If all conditions are not met, the run time calculation will not be modified.
If the configuration program is used to change the number of battery cabinets, then the values in Table 8-8
will be restored. This will override any value that is Auto-Learned.
