Appendix A Electromagnetic Compatibility
(EMC)
Background
The 380V 50/60Hz and 415V 50/60Hz CE marked ProLine 2200 plasma cutting
systems are manufactured to comply with the European standard EN 60974-10
(Electromagnetic compatibility (EMC) – Product standard for arc welding
equipment). The limits used in this standard are based on practical experience.
However, the ability of plasma cutting equipment to work in a compatible manner
with other radio and electronic systems is greatly influenced by the manner in
which it is installed and used. For this reason, it is important that the plasma
cutting equipment be installed and used in accordance with the information below
if electromagnetic compatibility is to be achieved.
Plasma cutting equipment is primarily intended for use in an industrial
environment. There may be potential difficulties in ensuring electromagnetic
compatibility in other environments.
Installation and Use
The user is responsible for installing and using the plasma cutting equipment
according to the manufacturer’s instructions. If electromagnetic disturbances are
detected then it shall be the responsibility of the user of the plasma cutting
equipment to resolve the situation with the technical assistance of the
manufacturer. In some cases this remedial action may be as simple as earthing
the plasma cutting circuit, see Note. In other cases it could involve constructing
an electromagnetic screen enclosing the plasma power source and the work,
complete with associated input filters. In all cases, electromagnetic disturbances
shall be reduced to the point where they are no longer troublesome.
Note: The plasma cutting circuit may or may not be earthed for safety reasons.
Changing the earthing arrangements should only be authorized by a person who is
competent to assess whether the changes will increase the risk of injury, e.g. by
allowing parallel plasma cutting current return paths which may damage the earth
circuits of other equipment. Further guidance is given in IEC 974-13
