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

Product Description

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

™

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.

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 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.

9Liebert

®

GXT4

™

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).

Product Description

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.
