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, Emerson
Network Power representative or Emerson Network Power 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% ~ 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 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.
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.
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 overcurrent protection.
