Electromagnetic Compatibility (Emc) - Lincoln Electric PRO-CUT 25 Operator's Manual

Electromagnetic Compatibility (EMC)

This machine has been designed in accordance with all relative directives and norms. 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.
WARNING: This machine has been designed to operate in an industrial area. To operate in a
domestic area it is necessary to observe particular precautions to eliminate possible
electromagnetic disturbances. The operator must install and operate this equipment as
described in this manual. If any electromagnetic disturbances are detected the operator must
put in place corrective actions to eliminate these disturbances with, if necessary, assistance from Lincoln
Electric Italia. Do not modify this machine without the written approval of Lincoln Electric Italia.
Before installing the machine, the operator must check the work area for any devices that may malfunction
because of electromagnetic disturbances. Consider the following.
• Input and output cables, control cables, and telephone cables that are in or adjacent to the work area and
the machine.
• Radio and/or television transmitters and receivers.
• Computers or computer controlled equipment.
• Safety and control equipment for industrial processes.
• Personal medical devices like pacemakers and hearing aids.
• Equipment for calibration and measurement.
• Check the electromagnetic immunity for equipment operating in or near the work area. The operator
must be sure that all equipment in the area is compatible. This may require additional protection
measures.
• The dimensions of the work area to consider will depend on the construction of the area and other
activities that are taking place.
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.
