Chapter 1 Introduction  
Congratulations on your choice of the Liebert® GXT4™ uninterruptible power system (UPS). The Liebert GXT4  
comes in nominal power ratings of 5000VA, 6000VA and 10,000VA. It is designed to provide conditioned power to  
microcomputers and other sensitive electronic equipment.  
When it is generated, alternating current is clean and stable. However, during transmission and distribution it is  
subject to voltage sags, spikes and complete power failure that may interrupt computer operations, cause data loss  
and even damage equipment. The Liebert GXT4 protects equipment from these disturbances.  
The Liebert GXT4 is a compact, on-line UPS. An on-line UPS continuously conditions and regulates its output voltage,  
whether utility power is present or not. It supplies connected equipment with clean, sinewave power. Sensitive  
electronic equipment operates best from sinewave power.  
The Liebert GXT4 features a multicolor LCD display to indicate load percentage, input/output voltage and current,  
runtime of battery and so on. It also provides self-diagnostic tests by visual configuration.  
The Liebert GXT4 can be operated at high efficiency mode (Green Mode) which efficiency could up to 97%.  
The Liebert GXT4 includes E models without rack slide kits for different requirement of user.  
The Liebert GXT4 has a Liebert IntelliSlot® port for communication between the UPS and a network server or other  
computer systems. This port provides detailed operating information including voltages, currents and alarm status to  
the host system when used in conjunction with Liebert MultiLink®. Liebert MultiLink can also remotely control UPS  
operation.

2.1 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 utility line and keep the  
sensitive equipment protected.  
2.2 Rectifier/Power Factor Correction (PFC) Circuit  
In normal operation, the rectifier/power factor correction (PFC) circuit converts utility 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 utility power is used as efficiently as possible by the UPS.  
The amount of distortion reflected on the utility is reduced.  
This results in cleaner power being available to other devices in the building not being protected by the Liebert®  
GXT4™.  
2.3 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 utility 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.  
2.4 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 connected to mains power.  
2.5 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.

2.6 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 11-5.  
2.7 Dynamic Bypass  
The Liebert GXT4 provides an alternate path for utility 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.  
NOTE  
The bypass power path does NOT protect the connected equipment from disturbances in the mains supply.

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.

Chapter 6 Configuration Program  
The final step of installation may require custom configuration of your UPS using the enclosed configuration program.  
Some configuration settings may be changed only while the UPS is off. These should be set before the UPS is put  
into full-time service powering the critical load.  
For most users operating with 230VAC and with no external batteries, the factory default settings will be adequate.  
6.1 Configuration Program Features  
Select L-N output voltages to match local voltages.  
Enable/Disable Auto-Restart.  
Select frequency converter operation with a fixed output frequency of 50 or 60 Hz.  
Set the Low Battery Warning alarm time from 2 to 30 minutes.  
Enable/Disable the Auto-Battery test.  
Set the Auto-Battery test to 8, 12, 16, 20 or 26 weeks.  
Specify the number of external battery cabinets connected to the UPS to adjust the remaining run time  
calculations reported by Liebert® software products.  
Modify the shutdown setting of the terminal block (for information on pin assignments, see Table 5-3).  
6.2 What You Will Need  
In addition to the Liebert GXT4™ UPS, you will need the configuration program CD and USB cable included in the  
UPS accessory box. A Windows 95® or later computer, desktop or laptop, is also required to set up and run the  
configuration program.

Figure 9-1 Terminal block communication pin layout  
9.2.1 Any-Mode Shutdown  
The purpose of Any Mode Shutdown is to shut down the UPS output by turning Off the rectifier, inverter and static  
switch so that there is no power to the loads.  
Any Mode Shutdown can be operated locally or remotely:  
Local Any Mode Shutdown can be performed by shorting the pins in Set 3.  
Remote Any Mode Shutdown can be performed using a switch connected to the pins in Set 3 and mounted at a  
remote location.  
Activation of the Any Mode Shutdown will be logged as an event in the event history log.  
Note  
Remote Power Off will be performed either by NO or NC contact of Any Mode Shutdown. The current limited source for the  
optocoupler (+12VDC, 50mA) will be available from UPS. The connection to UPS for remote connection will be via terminal  
block connector. Any Mode Shutdown wiring must conform to all national, regional and local wiring codes and laws.  
Warning  
When the Auto-enable output option is selected and the UPS output is disabled using the pins in Set 3, the Liebert GXT4’s output  
can turn On automatically and without warning if the connection of the pins in Set 3 is changed.  
9.2.2 Battery Mode Shutdown  
Battery Mode Shutdown permits shutting down the UPS by turning off the rectifier, inverter and static switch so that  
there is no power to the load when the UPS is On Battery. The auxiliary power for the UPS will still be active.  
Battery Mode Shutdown can be performed locally or remotely:  
Local Battery Mode shutdown can be performed by shorting the pins in Set 4.  
Remote Battery Mode Shutdown can be performed using a switch connected to the pins in Set 4 and mounted  
at remote location.

Note  
The internal battery pack is hot-swappable. However, caution should be exercised because the load is unprotected from  
disturbances and power failures during this procedure. Do not replace the battery while the UPS is operating in Battery Mode.  
This will result in a loss of output power and will drop the connected load.  
10.2 Battery Charging  
The batteries are valve-regulated, nonspillable, lead acid and should be kept charged to attain their design life. The  
Liebert® GXT4™ charges the batteries continuously when it is connected to the utility input power.  
If the Liebert GXT4 will be stored for a long time, Emerson recommends connecting the UPS to input power for at  
least 24 hours every four to six months to ensure full recharge of the batteries.  
10.3 Precautions  
Although the Liebert GXT4 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 GXT4 before cleaning it.  
Wear rubber gloves and boots.  
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 GXT4 power cord where it might be damaged.  
10.4 Checking 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 utility 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.  
10.5 Checking UPS Functions  
Note  
UPS function check procedures may interrupt power supply to the connected load.  
Emerson recommends checking the UPS functions once every six months.  
Back up the load data before conducting the UPS functions check. Procedures are as follows:  
1. Select Main Menu -> 3 CONTROL -> 1 TURN ON & OFF to enter the TURN ON & OFF screen, and select ‘TURN  
UPS BYPASS’ to transfer the UPS to bypass. Check whether the LCD display panel displays the warning normally.  
2. Select Main Menu -> 2 CONFIGURATION -> 3 OPERATION MODE to enter the OPERATION MODE screen (see  
Figure 3-11), and select ‘GREEN MODE ON’ or ‘GREEN MODE AUTO’ to control the UPS operation mode. Check  
whether the LCD display panel displays the mode normally.  
3. Select Main Menu -> 3 CONTROL -> 3 BATT TEST to enter the BATT TEST screen, and select ‘1 START’ to start  
manual battery test. Check whether the UPS can operate normally in Battery mode. If not, stop and contact your local

Table 11-5 shows the estimated run times at different loads.  
Auto-Learning Battery Run Times  
As batteries age, the estimated runtimes may become less accurate. The Liebert® GXT4 is programmed to “learn”  
from a full battery discharge and modify the estimated run time 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-of-discharge 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 Table 11-5 will be  
restored. This will override any value that is Auto-Learned.
