Liebert UHA1R-0100 User Manual page 4

The UPS complies with CE 2006/95/EC (LV Safety) and 2004/108/EC (EMC), and with the following product standards for
UPS:
 IEC 62040: 2008 General and safety requirements
 IEC62040-2: EMC requirements, Class C2 compliant
 IEC62040-3: Performance requirements and test methods
The UPS installation should follow the above instructions and use the accessories specified by the manufacturer.
1. Reliable earth connection is essential before the input power (AC mains and battery included) is connected.
2. Earth leakage current is bigger than 3.5mA, and less than 5% of the input current.
3. Transient and steady-state earth leakage currents, which may occur when starting the equipment, should be taken into
account when selecting instantaneous RCCB or RCD.
4. Note that the earth leakage current of the load will flow through the RCCB or RCD.
5. This equipment must be earthed in accordance with the local electrical codes.
Before operating the circuit, isolate the UPS firstly, and then check the dangerous voltage between the ports, and that
between the ports and earth.
1. All internal maintenance and servicing procedures of the equipment should be carried out only by trained personnel.
Components behind the protective cover which can only be removed by using a tool are restricted to service personnel.
2. The UPS meets the safety requirements completely in operator access area. Only service personnel can contact with the
hazardous voltage inside the UPS. However, the risk of contacting these voltages is minimized because the components
with hazardous voltage may be contacted only by using a tool to remove the protective cover. No risk will exist if you follow
the general norms and in accordance with the procedures recommended in this manual on equipment operation.
1. All the physical service and maintenance of the battery are performed by the trained technicians.
2. Operation on the battery will result in electric shock and high short-circuit current, therefore, before operating the battery,
the following should be observed:
 Remove the watches, rings and other metal objects.
 Use the tools with insulation handle.
 Weare rubber gloves and shoes.
 Avoid to place the tools and metal objects on the battery surface.
 Cut off the charge power supply before connecting or disconnecting the battery terminals.
 Check whether the battery is earthed accidently, if yes, please disconnect the earthing. Contacting any earth battery
parts will result in electric shock. Therefore, make sure that the battery is not earthed during installation and
maintenance.
3. Battery manufacturers provide the details of the precautions to be observed when working on, or in the vicinity of the
batterys. These precautions should be followed implicitly at all times. Attention should be paid to the recommendations
concerning local environmental conditions and the provision of protective clothing, first aid and fire-fighting facilities.
