Safety Instructions
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.

Safety Instructions
• In case of fire, use dry chemical fire extinguisher to put out the fire. Using foam fire
extinguisher may cause electric shock.
• High ambient temperature shortens the battery’s lifetime, so the battery should be
monitored & maintained periodically and if required should be replaced. This is to
ensure normal UPS operation and adequate autonomy time. Only an
Emerson-authorized technician is permitted to replace the battery. In replacement of
battery or battery module, please use the same model and number of battery or battery
module.
• It is recommended to place battery at a place with controlled ambient temperature. The
rated battery performance is available at 25 degree Celsius.
• Do not open or damage the battery, as the battery electrolyte is harmful to the eyes and
the skin. If electrolyte comes into contact with the skin, wash the affected area with
plenty of clean water and seek emergency medical assistance immediately

Product Introduction
Product Introduction
The GXT-RT series 1~3kVA UPS is an online UPS with a sine wave output, and is developed by
Emerson Network Power.
The GXT-RT provides highly efficient and reliable AC Power for your sensitive equipment.
The GXT-RT adopts a modular design. Rack installation and tower installation can be used depending
on the user’s requirements. It is an ideal product for applications that require small footprint, like
communication stations and data machine rooms.
1.1 Features
Product features include:
z 2U thick.
z Exceptional electrical performance, with an on-line efficiency up to 88%.
z High system reliability, self-protection and fault diagnosis are achieved using the advanced DSP-based
full digital control technology.
z The system adopts a high-frequency, double conversion topology structure to achieve a high input
power factor up to 0.99, greatly reducing its contamination to the power grids.
z With a wide range of input voltages, and an output immune to the mains interference, the product is
suitable even for areas with unstable mains power supply. It is an environmentally efficient energy
source.
z With a wide range of input frequencies, the product can be well connected to the generator output.
z Long Back up model has built-in large charger to satisfy users’ demand for extended battery back-up
time.
1.2 System Components
Power module and battery module are the basic components of GXT RT series UPS. The
former performs power conversion, provides AC output for load and charges the battery, while
the latter provides DC power for the UPS.
1.2.1 Power Module
Types and models
There are two types of power module: standard type and extended back-up time type, each
available in the following ratings: 1kVA, 2kVA and 3kVA.
The power module types and models appear from Table 1-1. Users can confirm the module
model by checking the nameplate on the enclosure.
