1.0 INTRODUCTION

Congratulations on your choice of the Liebert® GXT3™ 5000RT230U uninterruptible power system
(UPS). The Liebert GXT3 comes in a nominal power rating of 5000VA. 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 may be subject to voltage sags, spikes and complete power failure that may interrupt
computer operations, cause data loss and even damage equipment. The Liebert GXT3 protects
equipment from these disturbances.

The Liebert GXT3 is a compact, on-line UPS that continuously conditions and regulates its output
voltage, whether mains power is present or not. It supplies connected equipment with clean sinewave
power. Sensitive electronic equipment operates best from sinewave power.

For ease of use, the Liebert GXT3 features a light-emitting diode (LED) display to indicate both load
percentage and battery capacity. It also provides self-diagnostic tests, a combination ON/Alarm
Silence/Manual Battery Test button, a Standby/Manual Bypass button and a configuration program.

The Liebert GXT3 has a Liebert IntelliSlot
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.

System Description

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
mains 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 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

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 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.

®

GXT3™.

2.4 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 GXT3 is connected to
mains power.

5

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® GXT3™ 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.

2.7 Dynamic Bypass

The Liebert GXT3 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.

NOTE

The bypass power path does NOT protect the connected equipment from disturbances
in the mains supply.

placing the UPS or battery cabinet in the lowest
possible rack position.

3. Install the rear member of each bracket assembly into the
rack enclosure with two (2) M5 screws provided in this kit
(see figure at right). The return flanges on the bracket
assembly fit to the inside of rack mounting rails. Insert
screws loosely (finger-tight) into the top and bottom holes
of the return flange on the rear member. Extend the
bracket assembly by sliding the front member forward
until it touches the front rack mounting rail. Insert two (2)
M5 screws loosely (finger-tight) into the top and bottom
holes of the return flange on each front member. Make sure
that the bracket assemblies are at the same mounting
height on all four (4) rack mounting rails.

4. Get eight (8) M4 screws and eight (8) M4 nuts from the
hardware pack in this kit. Each nut has a locking, nylon
insert that begins gripping the screw when it is halfway
tight. Make sure to tighten the nut and screw completely to
ensure locking action. Fasten the rear member and the
front member together using (4) screws and (4) nuts per
bracket assembly as shown in at right. For maximum
support, insert fasteners for each bracket assembly as far
apart as possible, depending on rack depth, while still
joining both members (see figures at right). Check
alignment of bracket assemblies and TIGHTEN ALL
SCREWS FROM Steps 2 3.

5. Prepare the UPS or battery cabinet (the “equipment”) for
rack mounting by following instructions in the equipment’s
user manual. The equipment may require additional parts
to be added or parts to be removed for rack mounting. After
it is prepared, lay the equipment in rack-mounting

Load%

Using the configuration program, the user may specify the number of Liebert® external battery
cabinets attached to the UPS. The factory default is programmed for internal batteries only.

See Table 11 shows the estimated run times at different loads.

12.1 Auto-Learning Battery Run Times

As batteries age, the estimated runtimes may become less accurate. The Liebert GXT3™ is
programmed to “learn” from a full battery discharge and modify the estimated runtime 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 the
battery above table will be restored. This will override any value that is Auto-Learned.
