IMPORTANT SAFETY PRECAUTIONS

! WARNING

Risk of electric shock. Can cause equipment damage, injury or death.

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,

presenting 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%, non-condensing)

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.

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 Network Power® representative.

Battery Safety

! WARNING

Risk of electric shock and explosion. Can cause equipment damage, injury and death.

Do not dispose of the battery in a fire. The battery may explode.

Do not open or damage the battery. Released electrolyte is toxic and 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.

! WARNING

Risk of electric shock. Can cause equipment damage, injury and death.

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.

• Wear rubber gloves and boots.

• Do not lay tools or metal parts on top of batteries.

• Disconnect charging source prior to connecting or disconnecting battery terminals.

• Determine if the battery is inadvertently grounded. If it is inadvertently grounded, remove

the source of the ground. Contact with any part of a grounded battery can result in

electrical shock. The likelihood of such shock will be reduced if grounds are removed during

installation and maintenance (applicable to a UPS and a remote battery supply not having

a grounded supply circuit).

Battery

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 GXT4 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.

Rectifier/Power Factor Correction (PFC) Circuit

In normal operation, the Liebert GXT4’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 GXT4’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 GXT4 is plugged in,

even when the UPS is not turned On.

Liebert® GXT4™

Page 14

Product Description

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 GXT4 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery

design life, operate the Liebert GXT4 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 GXT4 provides an alternate path for mains power to the connected loads in the unlikely

event of a UPS malfunction. Should the Liebert GXT4 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,

Battery Recharge Mode, Active ECO Mode and Frequency Converter Mode.

Refer to 3.0 - Operation and Display Panel for details about the operating mode indicators and

control buttons.

1.5.1

Mains Mode

During Mains Mode, the mains provides input power to the Liebert GXT4. The filters, PFC circuit

and inverter process this power to provide high-quality sine wave power to connected loads. The UPS

maintains the batteries in a fully charged state.

1.5.2

Manual Bypass Mode

Manual Bypass Mode occurs when the unit is manually placed in internal bypass by navigating the

LCD display menu to select 3 Control > 1 Turn On & Off > Turn UPS Bypass. 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.

NOTICE

Risk of loss of power to the connected load. Can cause equipment damage.

Turning Off the UPS in Bypass Mode will result in loss of output power to the connected load.

Liebert® GXT4™

Page 15

Product Description

1.5.3

Battery Mode

The Liebert GXT4 enters Battery Mode when mains power fails or is outside acceptable limits. 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 GXT4 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 battery indicator will illuminate and the LCD will show the prompt Silence

Alarm and choices of Yes and No. The default is No. Press either the Up or Down arrow button to

select Yes, then press the Enter button to silence the alarm.

Once the alarm prompt has been acknowledged, the UPS will display the estimated battery run time

and battery capacity. Refer to 7.0 - Troubleshooting. For approximate battery run times, refer to

Table 17.

NOTICE

Risk of loss of power to the connected load. Can cause equipment damage.

Turning Off the Liebert GXT4 when it is in Battery Mode will result in loss of output power to

the connected load.

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 set 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 GXT4, the Battery Charger begins charging the batteries.

1.5.5

Frequency Converter Mode

All models of the Liebert GXT4 are capable of frequency conversion. Frequency Conversion Mode can

be selected using the configuration program. Allowable frequency operating modes include:

•

•

•

•

Auto Sensing - 50Hz or 60Hz – Bypass Enabled

Auto Sensing - 50Hz or 60Hz – Bypass Disabled

Frequency Converter - 50Hz – Bypass Disabled

Frequency Converter - 60Hz – Bypass Disabled

NOTE

The default for all models of the Liebert GXT4 is “Auto Sensing - 50Hz or 60Hz – Bypass

Enabled.”

! CAUTION

Risk of electric shock. Can cause injury or death.

Never touch the AC input receptacle while the UPS is operating. Voltage may still be present

even when the AC input indicator is Off.

1.5.6

Active ECO Mode

All Liebert GXT4 models can operate in Active ECO Mode. In this mode, the connected equipment is

powered through the bypass path to increase efficiency, reducing the electrical costs.

Active ECO mode keeps the rectifier and inverter operating, allowing the inverter to remain

synchronized to bypass. This synchronization allows the transfer of the connected equipment to UPS

inverter power almost seamlessly if bypass power falls outside the user-set limits. Once bypass power

returns within the acceptable parameters, the UPS will return to Active ECO Mode operation.

The default setting is Active ECO Mode Off.
