Lincoln Electric OERLIKON CITOSTEEL 255C Bedienungsanleitung Seite 9

Electromagnetic Compatibility (EMC)
This machine has been designed in accordance with all relevant directives and standards. However, it may still generate
electromagnetic disturbances that can affect other systems like telecommunications (telephone, radio, and television) or
other safety systems. These disturbances can cause safety problems in the affected systems. Read and understand this
section to eliminate or reduce the amount of electromagnetic disturbance generated by this machine.
Provided that the public low voltage system impedance at the point of common coupling is lower than:

56,4 mΩ for the CITOSTEEL 255C

56,4 mΩ for the CITOSTEEL 255C PRO

56,4 mΩ for the CITOSTEEL 325C

56,4 mΩ for the CITOSTEEL 325C PRO
This equipment is compliant with IEC 61000-3-11 and IEC 61000-3-12 and can be connected to public lowvoltage
systems. 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 system impedance complies with the impedance restrictions.
Consider the following guidelines to reduce electromagnetic emissions from the machine.

Connect the machine to the input supply according to this manual. If disturbances occur if may be necessary to take
additional precautions such as filtering the input supply.

The output cables should be kept as short as possible and should be positioned together. If possible connect the
work piece to ground in order to reduce the electromagnetic emissions. The operator must check that connecting the
work piece to ground does not cause problems or unsafe operating conditions for personnel and equipment.

Shielding of cables in the work area can reduce electromagnetic emissions. This may be necessary for special
applications.
The Class A equipment is not intended for use in residential locations where the electrical power is provided by the public
low-voltage supply system. There may be potential difficulties in ensuring electromagnetic compatibility in those
locations, due to conducted as well as radiated disturbances.
While a high electromagnetic field occurs, a welding current can fluctuate.
