4.13 Electromagnetic compatibility (EMC)
4.13.1 Interference caused by electromagnetic elds
Description
Fluctuating currents and voltages generate electromagnetic elds. Electromagnetic elds can
interfere with the operation of electrical devices.
Equipment that generate electromagnetic elds are called sources of interference. Sources of
interference are converters that have not been correctly installed, for example. On the other
hand, interference sinks are devices that are disturbed by electromagnetic elds, e.g. mobile
telephones.
The type of transmission is another distinguishing feature of interference. A source of
interference either transmits the interference to the sink through conduction or through
radiation.
4.13.2 Electromagnetic compatibility (EMC)
Description
Interference suppression measures increase the electromagnetic compatibility (EMC).
EMC interference suppression measures allow the device to function correctly. As a
consequence, the device is neither a source of interference for other devices nor an
interference sink that can be disturbed by other devices.

4.13.3 EMC category
Description
Together with the associated motors and encoders, including the connecting cables, the
converter forms a variable-speed drive. Product standard IEC61800‑3 denes the EMC
requirements for a variable-speed drive. Product standard IEC61800‑3 calls a variable-speed
drive a "Power Drive System" (PDS).
