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
pushbutton 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.
