Appendix A Electromagnetic Compatibility
(EMC)
Background
The 220/380V 50Hz and 415V 50Hz SR-100i plasma cutting systems are
manufactured to comply with the European standard EN 50199 (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
