1.4 Major Components
The operating principle of the UPS is illustrated in Figure 1-6.
Figure 1-6 Operating principle diagram
Liebert® GXT4™ User Manual 8
The UPS is composed of utility input, TVSS and EMI/RFI filters, rectifier/PFC, inverter, battery charger,
DC-to-DC converter, battery, dynamic bypass and UPS output.
Transient Voltage Surge Suppression (TVSS) and EMI/RFI Filters
The Liebert GXT4 has surge protection and filters that protect the connected load from power surges,
electromagnetic interference (EMI) and radio frequency interference (RFI). These features can minimize
any surges or interference present in the utility power. The filters also prevent surges or interference
generated by the UPS from adversely affecting devices connected on the same branch as the UPS.
Page 18
Product Description
Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the Liebert GXT4’s rectifier/power factor correction (PFC) circuit converts utility power
to regulated DC power for use by the inverter while ensuring that the wave shape of the input current used
by the UPS is near ideal. Extracting this sinewave input current achieves two objectives:
• Efficient power use by the UPS
• Reduced reflected harmonics
This results in cleaner power being available to other devices in the building not being protected by the
Liebert GXT4.
Inverter
In normal operation, the Liebert GXT4’s inverter utilizes the DC output of the PFC to produce precise,
regulated sine wave AC power. When utility power fails, the inverter receives DC power from the DC-to-DC
Converter. In either operation mode, the UPS inverter is online, continuously generating clean, precise,
regulated AC output power.
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 plugged in, even
when the UPS is not turned On.
DC-to-DC Converter
The DC-to-DC converter raises the DC voltage from the battery to the optimum operating voltage for the
inverter. This allows the inverter to operate continuously at its optimum efficiency and voltage, thus
increasing reliability.
Battery
The Liebert GXT4 uses valve-regulated, nonspillable, lead acid batteries. To maintain battery design life,
operate the Liebert GXT4 in an ambient temperature of 32°F to 77°F (0°C to 25°C).
Optional external battery cabinets are available to extend battery run times.
Dynamic Bypass
The Liebert GXT4 provides an alternate path for utility power to the connected loads in the unlikely event of
a UPS malfunction. Should the Liebert GXT4 have an overload, overtemperature or UPS failure condition,
the UPS automatically transfers the connected loads to bypass.
NOTE
The bypass power path does not protect the connected loads from disturbances on the utility.
1.5 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.
1.5.1 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.

GXT4™ User Manual
Page 19
Product Description
1.5.2 Manual Bypass Mode
Manual Bypass Mode occurs when the unit is manually placed in internal bypass by navigating the LCD
display 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.
1.5.3 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
run time and battery capacity will be visible. Refer to 7.0 - Troubleshooting.
For approximate battery run times, refer to Tab le 9-5.
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.
If the UPS is turned Off manually, it must be manually restarted after mains power returns.
If the UPS is turned Off by a communication signal or because the batteries are depleted, it will
operate as set in the configuration program for Auto-Restart (Refer to 5.2.1 - Configuration
Program).
1.5.4 Battery Recharge Mode
Once mains power is applied to the Liebert GXT4, the Battery Charger begins charging the batteries.
Liebert® GXT4™ User Manual 10
Page 20
Product Description
!
1.5.5 Frequency Converter Mode
All models of the Liebert GXT4 are capable of frequency conversion. Frequency Conversion Mode can be
selected using the configuration program. Allowable frequency operating modes include:
• Auto Sensing - 50Hz or 60Hz – Bypass Enabled
• Auto Sensing - 50Hz or 60Hz – Bypass Disabled
• Frequency Converter - 50Hz – Bypass Disabled
• Frequency Converter - 60Hz – Bypass Disabled
NOTE
The default for all models of the Liebert GXT4 is “Auto Sensing - 50Hz or 60Hz – Bypass
Enabled.”
CAUTION
Risk of electric shock. Can cause injury or death.
Never touch the AC input receptacle while the UPS is operating. Voltage may still be present even
when the AC input indicator is Off.
1.5.6 Active ECO Mode
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.
