IMPORTANT SAFETY PRECAUTIONS

! WARNING
Observe all cautions and warnings in this manual. Failure to do so may result in serious
injury or death.
Refer all UPS and battery service to properly trained and qualified service personnel. Do not
attempt to service this product yourself.
Opening or removing the cover may expose you to lethal voltages within this unit even when
it is apparently not operating and the input wiring is disconnected from the electrical source.
Never work alone.

SAVE THESE INSTRUCTIONS

This manual contains important safety instructions that must be followed during the installation and
maintenance of the UPS and batteries. Read this manual thoroughly before attempting to install or
operate this UPS.

UPS Safety Notes

The UPS contains no user-serviceable parts except the internal battery pack. Do not remove the
cover. Removing the cover may result in electric shock and will invalidate any implied warranty.
The UPS has an internal battery, so the output receptacles of the UPS may carry live voltage even if
the UPS is not connected to mains input power.
Before moving or rewiring the UPS, disconnect mains input power and the battery and make sure
that the UPS is completely shut down. Otherwise, the output terminal may carry live voltage, pre-
senting an electric shock hazard.
To ensure human safety and normal UPS operation, the UPS must be properly grounded before use.
When the UPS is connected to an IT power distribution system, the short-circuit protection device
must be installed on the neutral line.
Install and use the UPS in the following environments:
• Temperature: 0°C to 40°C (32-104°F); relative humidity: 0% to 95%)
• Out of direct sunlight
• Away from heat source
• Stable surface, not subject to vibrations or shocks
• Away from dust and other particulates
• Away from corrosive substances, salts and flammable gases
Keep the air inlet and outlet of the UPS unobstructed. Poor ventilation will increase the UPS internal
temperature and can shorten the life of the UPS and its batteries.
Keep liquid and other foreign objects away from the UPS.
In case of fire, use a dry chemical fire extinguisher to put out the fire. Using a fluid fire extinguisher
may cause electric shock.
This UPS is not intended for use with life support and other designated critical devices. Maximum
load must not exceed that shown on the UPS rating label. This UPS is designed for data processing
equipment. If uncertain, consult your local dealer or Emerson representative.

Battery Safety

! CAUTION
Do not dispose of the battery in a fire. The battery may explode.
Do not open or damage the battery. Released electrolyte is harmful to skin and eyes. If
electrolyte comes into contact with the skin, wash the affected area immediately with plenty
of clean water and get medical attention.

! CAUTION
A battery can present a risk of electrical shock and high short-circuit current. The following
precautions should be observed when working on batteries:
• Remove watches, rings and other metal objects.
• Use tools with insulated handles.
• Do not short-connect the battery terminals. The battery may catch fire.

ELECTROMAGNETIC COMPATIBILITY—The Liebert GXT3 Series complies with the limits for
a Class A digital device. Operating this device in a residential area is likely to cause harmful interfer-
ence that users must correct at their own expense.

The UPS is composed of mains input, TVSS and EMI/RFI filters, rectifier/PFC, inverter, battery char-
ger, 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 objec-
tives:
• 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.

1.5 Operating Mode

The UPS operation modes include the following: Mains (AC) Mode, Bypass Mode, Battery Mode, Bat-
tery Recharge Mode and Frequency Converter Mode.
For the descriptions of operation mode indicators and control buttons, refer to 3.0 - Operation and
Display Panel.

1.5.1 Mains (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 main-
tains the batteries in a fully charged state.

7
 Product Description

1.5.2 Manual Bypass Mode

Manual Bypass Mode occurs when the Standby/Manual Bypass button is pressed once while the Lie-
bert 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.

1.5.3 Battery 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 inter-
vals. 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 approxi-
mate. 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 bat-
tery cabinets.

! 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).

1.5.4 Battery Recharge Mode

Once mains power is applied to the Liebert GXT3, the Battery Charger begins charging the batteries.

1.5.5 Frequency 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 connection to the Liebert GXT3 for remote connection will be via terminal block connector.
Battery Mode Shutdown wiring must conform to all national, regional and local wiring codes
and laws.
This signal must last for 1.5 seconds or longer.
A battery shutdown signal will not cause an immediate shutdown. It will start a 2-minute
shutdown timer. This timer cannot be stopped once triggered. If the mains power returns
during this countdown, the Liebert GXT3 will still shut down and must remain shut down for
10 seconds. Whether the UPS turns back on when the power is restored depends on the
auto-restart setting.

5.3.3 On Battery
On Battery signal is a Normally Open (NO) dry contact. When the UPS is supplying output power
from the battery this dry contact will be closed.

5.3.4 Low Battery

Low Battery signal is a Normally Open (NO) dry contact. When the UPS is supplying output power
from the battery and has reached the Low Battery Warning time selected in the configuration pro-
gram, this dry contact will be closed.

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 Emer-
son representative immediately.
• Do not dispose of batteries in a fire. The batteries may explode.
• Handle, transport and recycle batteries in accordance with local regulations.

6.3 Precautions
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.

6.4 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 mains input is normal, the battery should
not discharge. If the UPS is operating in Battery Mode, stop and contact your local Emerson rep-
resentative or Emerson Channel Support.
