Battery
The UPS is composed of mains input, TVSS and EMI/RFI filters, rectifier/PFC, inverter, battery
charger, DC-to-DC converter, battery, dynamic bypass and UPS output.
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.
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.
Liebert® GXT4™

Product Description
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 cabinets are available to extend battery run times. For run times, see Table 16.
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 that is located in a removable section of the
rear of the UPS. This allows replacement of the UPS, in the unlikely event of a UPS malfunction,
while keeping the connected equipment powered with mains power.
NOTE
The bypass power path does NOT protect the connected equipment from disturbances
in the mains supply.
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 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.
9
Liebert® GXT4™
Product Description
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 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 Table 16.
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).
1.7.4
Battery Recharge Mode
Once mains power is applied to the Liebert GXT4, the Battery Charger begins charging the batteries.
1.7.5
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.
1.7.6
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.

2.4.2
Rack Installation
The Liebert GXT4 UPS and external battery cabinets (EBC), when installed in a rack enclosure, must
be supported by a shelf or rack-mount rails. The Liebert GXT4 UPS and EBC units ship with all
required hardware to allow rack-mount installation (not included with model numbers that end in
“E”). Because different rack-mount options install differently, refer to the installation instructions
provided with the rack-mount kit being used.
2.4.3
External Battery Cabinet Installation
Optional Liebert external battery cabinets may be connected to the UPS to provide additional battery
run time. External battery cabinets are designed to be placed on one side of the UPS or stacked
beneath the UPS. External battery cabinets can be used in either a rack-mount or tower
configuration.
! CAUTION
The external battery cabinet(s) are heavy (see 8.0 - Specifications). Take proper precautions
when lifting them.

Battery Cabinets
1. Visually inspect the external battery cabinet for freight damage. Report damage to the carrier
and your local dealer or Emerson® representative.
2. For slide rail installations, first remove the top/side fin. Top/side fin slides forward and then lift
up to remove. Optional rack-mount handles are shipped with the external battery cabinet and
may be installed at this time if desired.
3. Securing hardware and slide rails are sold separately. Please contact your local dealer or
Emerson representative for these additional options and any assistance needed. Fasten the slides
into position with the screws per the instructions included with the slide rails.
4. Use the enclosed support bases for the tower option to prevent tip-over. One additional set of
support base extensions ships with each external battery cabinet.
5. Verify the External Battery Cabinet breaker is in the Off position.
6. Connect the supplied external battery cabinet cable to the rear of the external battery cabinet,
then to the rear of the UPS.
7. Turn the External Battery Cabinet breaker to the On position.
8. Configure the number of external battery cabinets connected to the UPS using either the LCD or
the configuration program on the CD that shipped with the UPS.
• If using the configuration program to set the number of external battery cabinets, refer to the
manual on the CD for assistance.
• If using the LCD, refer to Figure 26 for assistance in setting the number of battery cabinets.
9. The UPS is now equipped with additional backup battery run time. For approximate battery run
times, refer to Table 16.

Liebert® GXT4™
Installation
NOTE
When removing the External Battery Cabinet, the circuit breaker on the rear of the cabinet
must be turned Off before disconnecting the cable.
NOTE
If the UPS is to be shipped or stored for an extended time, the connector should be
disconnected. This will minimize any standby current drain on the batteries and help attain
their design life.

Distribution Box Electrical Connections
Electrical connections are made through a removable power distribution box that attaches to the rear
of the UPS.
• PD2-CE6HDWRMBS fits the 5000 and 6000VA models of the Liebert GXT4
• PD2-CE10HDWRMBS fits the 10,000VA model of the Liebert GXT4
The installer must provide an upstream branch circuit breaker. The input circuit breaker on the
distribution box and the output circuit breaker on the rear of the power distribution box disconnect all
power between the main cabinet and the distribution box.
Models equipped with a manual bypass breaker pass bypass power directly to the bypass breaker
from the input terminal block. The input circuit breaker on the distribution box does not disconnect
power from the manual bypass breaker.

Run times in this table are approximate. They are based on new, fully charged standard battery modules at a temperature of 25°C
(77°F) with 100% resistive UPS loading. Run times listed above can vary by ±5% due to manufacturing variances of the batteries.
Using the configuration program, the user may specify the number of GXT4-240VBATT external
battery cabinets attached to the UPS. The factory default is programmed for internal batteries only.
Table 16 shows the estimated run times at different loads.

Liebert® GXT4™
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 runtime 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-ofdischarge 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 the
battery above table will be restored. This will override any value that is Auto-Learned.
