1.3Appearance and Components
1.3.1Appearance
The Liebert GXT3 rack/tower models in various power ratings have the same general appearance,
controls and features (see Figure 1). The various rack/tower models differ largely in the type of
receptacles each has.
The operating principle of the UPS is shown in Figure 5.
Figure 5Operating 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 GXT3 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.
6
Product Description
Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the Liebert GXT3’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 GXT3’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 GXT3 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,
increasing reliability.
Battery
The Liebert GXT3 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery
design life, operate the Liebert GXT3 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 GXT3 provides an alternate path for mains power to the connected loads in the unlikely
event of a UPS malfunction. Should the Liebert GXT3 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.
1.5Operating Mode
The UPS operation modes include the following: Mains (AC) Mode, Bypass Mode, Battery Mode, Battery Recharge Mode and Frequency Converter Mode.
For the descriptions of operation mode indicators and control buttons, refer to 3.0 - Operation and Display Panel.
1.5.1Mains (AC) Mode
During Mains (AC) Mode, the mains provides energy to the Liebert GXT3. The filters, PFC circuit and
inverter process this power to provide high-level power to connected loads. Meanwhile, the UPS maintains the batteries in a fully charged state.
7
1.5.2Manual Bypass Mode
Manual Bypass Mode occurs when the Standby/Manual Bypass button is pressed once while the Liebert GXT3 is in Mains (AC) Mode. 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.
CAUTION
!
Turning off the UPS in Bypass Mode will result in loss of output power.
1.5.3Battery Mode
The Liebert GXT3 enters Battery Mode when mains power fails or is outside acceptable values. 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 GXT3 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 AC Input indicator is Off and the Battery Level indicators illuminate to warn
that a mains problem has occurred. Each battery level indicator represents a 20% capacity level. As
capacity decreases, fewer indicators remain illuminated. Refer to 7.0 - Troubleshooting.
For approximate battery run times, refer to 9.0 - Specifications. The times in Table 14 are approximate. They are based on resistive load and an ambient temperature of 25°C (77°F). To increase this
time, turn off non-essential loads (such as idle computers and monitors) or add optional external battery cabinets.
Product Description
CAUTION
!
Turning Off the Liebert GXT3 when it is in Battery Mode will result in loss of output power.
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 selected in the configuration program for Auto-Restart (Refer to 5.2.1 - Configuration Program).
1.5.4Battery Recharge Mode
Once mains power is applied to the Liebert GXT3, the Battery Charger begins charging the batteries.
1.5.5Frequency Converter Mode
All models of the Liebert GXT3 are capable of frequency conversion. Frequency Conversion Mode can
be selected using the configuration program. Allowable frequency operating modes include:
• Auto Sensing - 50Hz or 60 Hz – Bypass Enabled
• Auto Sensing - 50Hz or 60 Hz – Bypass Disabled
• Frequency Converter - 50Hz – Bypass Disabled
• Frequency Converter - 60Hz – Bypass Disabled
NOTE
The default for all models of the Liebert GXT3 is “Auto Sensing - 50Hz or 60 Hz – Bypass
Enabled.”
CAUTION
!
Do not touch the AC input receptacle when the UPS is operating. AC input voltages may still
be present even when the AC input indicator is Off.

The battery can present a risk of electrical shock and high short circuit current. The following
precautions should be observed before replacing the battery pack:
• Remove rings, watches and other metal objects.
• Use tools with insulated handles.
• Do not lay tools or other metal objects on the batteries.
• If the battery kit is damaged in any way or shows signs of leakage, contact your local Emerson representative immediately.
• Do not dispose of batteries in a fire. The batteries may explode.
• Handle, transport and recycle batteries in accordance with local regulations.
6.3Precautions
Although the Liebert GXT3 has been designed and manufactured to ensure personal safety, improper
use can result in electrical shock or fire. To ensure safety, observe the following precautions:
• Turn Off and unplug the Liebert GXT3 before cleaning it.
• Clean the UPS with a dry cloth. Do not use liquid or aerosol cleaners.
• Never block or insert any objects into the ventilation holes or other openings of the UPS.
• Do not place the Liebert GXT3 power cord where it might be damaged.
6.4Checking UPS Status
Emerson recommends checking the UPS operation status every six months.
• Check whether the UPS is faulty: Is the Fault Indicator on? Is the UPS sounding an alarm?
• Check whether the UPS is operating in Bypass Mode. Normally, the UPS operates in Normal
Mode. If it is operating in Bypass Mode, stop and contact your local Emerson representative, or
Emerson Channel Support.
• Check whether the battery is discharging. When the mains input is normal, the battery should
not discharge. If the UPS is operating in Battery Mode, stop and contact your local Emerson representative or Emerson Channel Support.
