Safety Precautions
This manual contains the information concerning the installation and operation of Liebert
®
ITA 5kVA and 6kVA
UPS (hereinafter referred to as UPS).
Please carefully read this manual prior to installation.
Warning
1. The UPS must be installed and commissioned by engineers designated by the manufacturer or its agent. Failure to
observe this could result in personnel safety risk, UPS malfunction and invalidation of warranty.
2. The UPS has been designed for commercial and industrial use only, and is not recommended for use in life support
applications.
3. This is a Class A UPS product. In a residential environment, this product may nevertheless cause radio interference, in
which case, the user is required to take additional measures to reduce the interference.
4. Never dispose of the battery module in a fire because it may explode and endanger personnel safety when exposed to
flame.
Note
1. The standard UPS has the external battery module, therefore, the output terminals of the UPS may carry live voltage even
when the UPS is not connected to the AC mains.
2. Before moving or re-wiring the UPS, please disconnect all the inputs and make sure the UPS is completely shutdown. Or
else, the output end may carry live voltage.
3. The operating environment and the saving method affect the life and reliability of the UPS, don not use the UPS in the
following environments:
Places where the temperature and relative humidity are outside the technical specification (temperature: 0°C ~ 40°C,
relative humidity: 5%RH ~ 95RH).
Places where direct sunlight and near heat source are present.
Places where vibrations or shocks are present.
Places where the dusty, corrosive substances, salts, or flammable gases are present.
4. Keep the air inlet and outlet well-ventilated. Poor ventilation will increase the internal temperature, which will shorten the
life of the UPS components and that of the UPS.
5. Liquid or other irrelevant external objects are prohibited inside the UPS.
6. In case of fire, a dry chemical fire extinguisher is essential. Using a foam fire extinguisher will cause electric shock.
7. The life of the battery module will be shortened with the rise of the ambient temperature. To ensure normal UPS operation
and enough back-up time, the battery module should be replaced periodically. Only the Emerson-authorized technicians are
permitted to replace the battery module.
8. If the UPS will remain idle for a long time, it must be stored in a dry environment. The storage temperature should range
between -20°C and +55°C for standard UPS (with battery module), between -40°C and +70°C for long back-up UPS (with no
battery module).
9. The UPS is a professional equipment with a total rated power greater than 1kW. The equipment complies with IEC
61000-3-12 provided that the short-circuit ratio Rsce is greater than or equal to 250 at the interface point between the user’s
power supply and the public system. It is the responsibility of the installer or user of the equipment to ensure, by consultation
with the distribution network operator if necessary, that the UPS is connected only to a power supply with a short-circuit ratio
Rsce greater than or equal to 250.
10. The UPS output cable must be not longer than 10m.
11. The backfeed protection unit is external. For the using method, refer to
UF-BFP-63A Backfeed Protection Unit User
Manual
.
12. Normal mode, the output neutral line of the UPS is connected with the input neutral line. Upon the mains failure, the
output neutral line will be suspended, which results in the output neutral line unconnected.
