Webinar for EMC.

Schaffner are running a free Webinar on best practice design for EMC compliance of Industrial Equipment and Machines. Intended for manufacturers of variable-frequency drives and machine and control cabinet builders, all EMC-specific aspects of the latest international standards, their implementation and relevant solutions will be presented.

Holger Urban, Product Marketing Manager of Schaffner, comments, “EMC affects every part of everyday life but its effects are most serious in manufacturing systems where EMC disturbances can shut manufacturing process down completely. Our webinar will provide designers and system integrators with a range of tools and solutions to ensure the correct design of reliable industrial systems.”

EMC (electromagnetic compatibility) has steadily increased in importance with the increased use of variable-frequency drives in industrial applications and will continue to grow as applications in SMART factories, Industry 4.0, the IoT and industrial automation increase.

As the needs for automated industrial production expand and the demand for artificial intelligence increases, systems are becoming more and more complex and the costs of any breakdown in the production of goods, both products and services, is of growing concern to manufacturers.

It has never been more important that electrical and electronic devices are designed and constructed in such a way that it complies with the EMC directives and standards with regard to interference immunity and interference emissions and that they are coordinated with each other in any system. (Links to the EU Electromagnetic Compatibility (EMC) Directive may be found on line.)

In addition to the Machinery Directive, the legally binding EMC Directive, among others, must be complied with if machines cause electromagnetic interference or are impaired in their function by such interference.

According to the EMC Directive, machines and systems are equipment that must be designed and manufactured in compliance with the main requirements of Annex I of the EMC Directive. Only then a certificate of conformity may be issued for the machine, system, device (incl. control cabinet) and the CE mark may be applied.

The EMC Directive defines electromagnetic compatibility in Europe as follows:
"the ability of an apparatus, installation or system to operate correctly in its electromagnetic environment without causing electromagnetic interference which would prevent any other apparatus, installation, machine or system in this environment from operating as intended."

In effect the EMC Directive applies not only to manufacturers of variable-frequency drives, but also to machine and control cabinet builders and system integrators. In order to do consider these various industrial suppliers and industrial market participants, appropriate standards have been defined for this purpose to ensure an effective cooperation.
