Basic information about EMC

What is EMC?
EMC stands for "electromagnetic compatibility" and describes "the capability of a device to
function satisfactorily in an electromagnetic environment without itself causing interference
unacceptable for other devices in the environment". Therefore, the various units used should
not cause interference to one another.
Within the context of the EMC Directive, the SINAMICS DC MASTER units described in this
document are not "units" at all, but are instead "components" that are intended to be
installed in an overall system or overall plant. For reasons of clarity, however, the generic
term "units" is used in many cases.
Interference emissions and interference immunity
EMC is dependent upon two properties demonstrated by the units involved in the system:
interference emissions and interference immunity. Electrical units may be sources of
interference (senders) and/or potentially susceptible equipment (receivers).
Electromagnetic compatibility is ensured when the existing sources of interference do not
impair the function of potentially susceptible equipment.
A unit may even be a source of interference and potentially susceptible equipment at the
same time: For example, the power unit of a converter unit should be viewed as a source of
interference and the control unit as potentially susceptible equipment.
