Chapter 1 Introduction

Congratulations on your choice of the Liebert® GXT4™ uninterrup t ibl e power sys tem ( UPS). The Liebert GXT4
comes in nominal power ratings of 5000VA, 6000VA and 10,0 00VA. It is designed to provide conditioned power to
microc ompu ters and other sensiti ve electroni c equi pment.

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 L iebert 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 sine wave power.

The L iebert GXT4 f eatures a m ulticolor LCD display t o indicat e loa d perc entage, input/output voltage and current,
runtime of b attery an d so on. It al so provid es 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 wi thou t rack sli de kit s f or di fferen t 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 det a iled opera ting information includ ing voltages, currents and alarm status to
the host system when used in conjunction with Liebert MultiLink®. Liebert MultiLink c an also remotely contr ol UPS
operation.

igure 2-1 Operating principle diagram

F

2.1 Transient Voltage Surge Suppression (TVSS) and EMI/RFI Filters

Thes e UPS c omp onents provide sur ge protection and fi l ter both elect romagnet ic i nterference (EMI ) and ra dio
frequency interference (RFI). They minimize any surges or interference present in the utility line and keep the
sensitive equi pment protected.

2.2 Rectifier/Power Factor Correction (PFC) Circuit

In normal operation, the rectifier/power fac tor c orrection (P FC) circuit conver t s uti lity AC power to regula ted D C 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 t he uti lity is r educed.

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 th e D C out put of the po wer fact or cor rection c i rcuit and inverts it into precise,
regula ted sinew ave AC po wer. Upon a utility power failur e, the i nver ter r eceives its required en ergy f rom t he battery
through the DC-to-DC converter. I n both modes of oper at ion, the U PS in verter 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 b atter ies are b eing charged whenever the Liebert GXT 4 is connected t o mains power.

2.5 DC-to-DC Converter

The DC-to-DC con verter utilizes en ergy from the b attery system and r aises the DC voltage to th e optimum operating
voltage for t he inverter. This allows t he inverter to oper ate con tin uously at its optimum efficiency and voltage, thus
inc reas ing reli abil ity.

Liebert GXT4 UPS 5000VA ~ 10000VA (230V) User Manual

2.6 Battery

The L iebert® GXT4™ utilizes valve-regul ated, nonspil lable, lead acid b att er ies. To maintai n battery design life,
operate the UPS in an ambient temperature of 15°C to 25°C (59°F to 77°F). Optional extern al ba ttery cabinet s are
ava ila ble t o extend battery run times. For run ti mes, 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.

Using t he con f iguration progr am, t he user m ay sp ecif y the n umber of external b att ery ca binet s attached to the UP S.
The fact ory defa ult is prog rammed for internal bat teries only.

Table 11-5 shows the estimated run times at different loads.

Auto-Learning Battery Run Times

As b atter ies age, t he estimated runti mes may become less accurate. The Liebert® GXT4 is programmed to “learn”
fr om a full battery discharge a nd modify t he estimated run ti m e for the measured battery capacity. This can improve
accuracy an d comp ensa te for aging bat teries or batteries that o pera te at different ambient temperatures.

The UPS will update the anticipated run time calculation only under certain conditions.

 The UPS mus t have a steady lo ad 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 ru n t im e calculation will n ot be modif ied.
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.
