Safety Precautions - Liebert UHA1R-0100 User Manual

This user manual contains the information concerning the installation and operation of Liebert
(hereinafter referred to as UPS).
Please carefully read this user manual prior to installation.
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
that 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.
1. The standard UPS has the external battery module, the output terminals of the UPS may carry live voltage even when
the UPS is not connected to AC mains.
2. Before moving or re-wiring the UPS, disconnect all the inputs and make sure that the UPS is completely shutdown. Or
else, the output end may carry live voltage.
3. The operating environment and the storage method will affect the life and reliability of the UPS, it is not recommented to
use the UPS for a long time 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 ~ 95%RH).
 Places where direct sunlight and near heat source are present.
 Places where vibrations or shocks are present.
 Places where 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 a fire, a dry chemical fire extinguisher is essential. Using a foam fire extinguisher will cause an electric shock.
7. The life of the battery module will be shortened with the rise of the ambient temperature. To ensusre noraml UPS
operation and enough back-up time, the battery module should be replaced periodically. Only 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 be
-20° C ~ +55° C for standard UPS (with battery modules), and be -40° C ~ +70° C for long back-up UPS (with no battery
modules).
9. The UPS is a professional equipment with a total rated power larger than 1kW. The equipment complies with IEC
61000-3-12 provided that the short-circuit ratio is larger than or equal to 250 at the interface point between the user's power
supply and the power grid. It is the responsibility of the installer or user of the equipment to ensure, by consultation with the
power supply department if necessary, that the UPS is connected only to a power supply with a short-circuit ratio Rsce
larger 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. In 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.
