TABLE OF CONTENTS The title of this book is EMC for Product Designers and that is its primary focus. But many individual products, that is electronic equipment and apparatus, are actually put together in systems which are required to function as a whole. This then changes the EMC context. There are now two aspects to consider: the compatibility with each other of the various items of equipment within the system, which we can call intra-system EMC; and the compatibility of the whole system with its environment and with other systems and apparatus in that environment, which we can call inter-system EMC. A complete view must take into account both aspects.
Designers of products which are going to be used in this way need to be aware of the two aspects, as do the designers and installers of the systems themselves. A companion book to this one, called EMC for Systems and Installations [22], treats the subjects raised by EMC at this level in much greater detail, and the systems designer is recommended to that book for further reading. Meanwhile, this chapter will serve as an introduction to the issues that face systems designers, from the point of view of a product designer whose projects must be capable of installation and interfacing at the systems level. Some of these issues have to do with the EMC compliance of the whole system, but more of them are related to interactions between equipment that may be installed...
