1 IMPORTANT SAFETY PRECAUTIONS

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

This UPS contains no user-serviceable parts except the internal battery pack. The Off/Bypass

pushbutton does not electrically isolate internal parts. Under no circumstances attempt to gain internal

access other than to replace the batteries due to risk of electric shock or burn. Do not continue to use the

UPS if the front panel indications are not in accordance with these operating instructions or if the UPS

performance alters in use. Refer all faults to your local dealer, Vertiv representative or Vertiv Channel

Support.

This UPS has an internal battery, and the output receptacles of the UPS may carry live voltage even if the

UPS is not connected to utility input power.

Before moving or rewiring this UPS, disconnect utility 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, a short-circuit protection device must be

installed on the neutral line.

Install and use the Liebert® GXT4 in the following environments:

•Temperature: 32°F - 104°F (0°C - 40°C), relative humidity: 0% to 95% non-condensing

•Out of direct sunlight

•Away from heat sources

•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 this UPS unobstructed. Poor ventilation will increase the internal

temperature of the UPS and can adversely affect the UPS and its batteries.

Keep liquid and 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 product is designed for commercial/industrial use only. 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

Vertiv representative.

This UPS is not for use in a computer room as defined in the standard for the Protection of Electronic

Computer/Data Processing Equipment, ANSI/NFPA 75.

1 Important Safety Precautions 5

The Liebert® GXT4-3000RT120™was tested under 30A branch circuit in accordance with the National

Electrical Code, ANSI/NFPA 70. To reduce the risk of fire, connect only to a circuit provided with 30A

maximum branch over-current protection.

The Liebert® GXT4-3000RT208 was tested under 20A branch circuit in accordance with the National

Electrical Code, ANSI/NFPA 70. To reduce the risk of fire, connect only to a circuit provided with 20A

maximum branch over-current protection.

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.

•If the battery kit is damaged in any way or shows signs of leakage, contact your local Vertiv

representative immediately.

•Handle, transport and recycle batteries in accordance with local regulations.

•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).

ELECTROMAGNETIC COMPATIBILITY The Liebert® GXT4 series complies with the limits for a CLASS A

DIGITAL DEVICE, PURSUANT TO Part 15 of FCC rules. Operation is subject to the following conditions:

•This device may not cause harmful interference.

•This device must accept any interference received, including interference that may cause

undesired operation.

Operating this device in a residential area is likely to cause harmful interference that users must correct

at their own expense.

The Liebert® GXT4 series complies with the requirements of EMC Directive 2004/108/EC and the

published technical standards. Continued compliance requires installation in accordance with these

instructions and use of accessories approved by Vertiv.

2 GXT4 DESCRIPTION

The Liebert® GXT4 is a compact, online uninterruptible power system (UPS) that continuously conditions

and regulates its output voltage. The Liebert® GXT4 supplies microcomputers and other sensitive

equipment with clean sine-wave input power.

Upon generation, AC power is clean and stable. However, during transmission and distribution it is subject

to voltage sags, spikes, and complete failure that may interrupt computer operations, cause data loss, and

damage equipment.

The Liebert® GXT4 protects equipment from these disturbances. The Liebert® GXT4 continuously

charges its batteries from the utility power, enabling it to supply power to connected loads, even when the

mains fail.

2.1 Features

•Intelligent battery management to extend the battery life

•LCD for user-friendly operation and local monitoring and configuration of operational

parameters

•Controllable outlet groups

•Fan fault self-inspection and automated diagnostic function

•Intelligent fan operation, automatically changing rotation speed depending on system

requirements, to decrease power consumption and noise

•Input circuit breaker to ease recovery from overloads

•Safety approval from UL and cUL

•Communication options: USB port, Liebert® IntelliSlot™ port and terminal-block communication

•Dry contacts for remote monitoring

•Input power factor greater than0.99

•Output voltage selection function
