The operating principle of the UPS is shown in Figure 6.

Figure 6 Operating principle diagram

Product Description

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.

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
and sags, electromagnetic interference (EMI) and radio frequency interference (RFI). These features
can minimize any surges or interference present in the mains power. The filters also prevent surges
or interference generated by the UPS from adversely affecting other devices connected on the same
branch as the UPS.

Rectifier/Power Factor Correction (PFC) Circuit

In normal operation, the Liebert GXT4’s rectifier/power factor correction (PFC) circuit converts mains
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 sine wave 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 that are not protected by
the UPS.

Inverter

In normal operation, the Liebert GXT4’s inverter utilizes the DC output of the PFC circuit to produce
precise, regulated sine wave AC power. When mains power fails, the inverter receives DC power from
the battery through 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 mains 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.

7Liebert

®

GXT4

™

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,
increasing reliability.

Battery

The Liebert GXT4 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery
design life, operate the Liebert GXT4 in an ambient temperature of 0°C to 25°C (32°F to 77°F).

Optional external battery cabinets are available to extend battery run times.

Dynamic Bypass

The Liebert GXT4 provides an alternate path for mains 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 mains.

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.

Product Description

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.

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.

Liebert® GXT4

™

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 Silence
Alarm and choices of Yes and No. The default is No. Press either the Up or Down arrow button to
select Yes, then press the Enter button to silence the alarm.

Once the alarm prompt has been acknowledged, the UPS will display the estimated battery run time
and battery capacity. Refer to 7.0 - Troubleshooting. For approximate battery run times, refer to

Table 17.

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

1.5.4 Battery Recharge Mode

Once mains power is applied to the Liebert GXT4, the Battery Charger begins charging the batteries.

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.
