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. 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 UPS 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
