    Introduction

    Who is this brochure intended for?

    This brochure is mainly aimed at commissioning engineers and installers of drives with low-power frequency converters. Such drives are found in commercial and industrial operations, as they are based in residential areas or mixed residential, office and industrial areas, so-called mixed areas.

    The brochure gives information that is easy to implement when selecting equipment and setting up the drives.

    In the list of references in the appendix, the brochure refers to more detailed documents, which you can download from the Internet.

    Why is this informational brochure important?

    Every electrical device affects its environment and other electrical devices.


    Figure: Examples of electrical devices that can be affected

    The influencing effect depends on the type, design and size of the device.


    Figure: Possible interference of electronic devices due to non-EMC-conformant design and/or installation

    An EMC-conformant design of the device by the manufacturer and correct installation by the system installer allow for the legal limit values of the influencing effect to be complied with without any problems. Thus, no other electrical devices are affected.


    Figure: No interference with other devices due to an EMC-conformant design and installation

    For interference-free operation of electrical and electronic devices, the requirements and limit values of electromagnetic compatibility (EMC) are defined in directives and standards.
