Safety Instructions
Caution - risk of electric shock. Even after the unit is disconnected from the mains power supply
(building wiring socket outlet), components inside the UPS system are still connected to the
battery and are still electrically live and dangerous.
Before carrying out any kind of servicing and/or maintenance, disconnect the batteries and
verify that no current is present and no hazardous voltage exists in the terminals of high
capacity capacitors such as BUS-capacitors
• As dangerous voltages are present within the UPS, only an Emerson technician or an
Emerson-authorized technician is permitted to open it. Failure to observe this could
result in electric shock risk and invalidation of any implied warranty.
• When the UPS is purchased to deliver power to the equipment listed below, please
discuss with the Emerson or Emerson Authorized Representative in advance about the
applicability, settings, management and maintenance of the UPS.
• The Liebert GXT-RT has been designed for Commercial/Industrial use only, and is not
recommended for use in life support applications
• Never dispose of the battery in a fire, as it may explode when exposed to flame.
• Do not apply pure inductive load to the UPS.
• The UPS has its own energy source (i.e., a battery), therefore the output terminal of the
UPS may carry live voltage even when the UPS is not connected to the AC mains.
• Before moving or re-wiring the UPS, please disconnect the mains source and make
sure the UPS is completely shut down. Otherwise the output terminal may carry live
voltage, presenting risk of electric shock.
• To ensure safety and normal operation, the UPS must be solidly and adequately
grounded before use.
• The operating environment and storage method are two main factors affecting the
lifetime and reliability of the UPS. Hence, it is advisable not to use the UPS for longer
periods in the following environments:
• Places where the temperature and relative humidity are outside the
specifications (specified temperature: 0°C~40°C, specified relative humidity:
5%~95%);
• Places where vibrations or shocks exist;
• Places which are dusty, strewn with corrosive substances or salts or where
flammable gases are present.
• Verify that the cabling and battery cable polarity are correct before switching on the
UPS.
•
The external battery must be fitted with an appropriate overcurrent protection device.
• The UPS installation must be firm and solid. The AC input socket that feeds the UPS
should be located near the UPS, and easy to access.
