Introduction to EMC

Electromagnetic compatibility (EMC) is the capability of a piece of electrical
equipment to function fault and error free in a specified electromagnetic
environment and without influencing that environment in an inadmissible fashion.
EMC thus represents the quality feature

In order to guarantee disturbance-free drive converter operation in the plant or
system, the noise in the environment may not be neglected. Thus, special
requirements are placed on the design and EMC of the system or plant.
In order to achieve the highest possible operational safety and noise immunity of a
complete system or plant (drive converter, automation system, drive motor etc.),
the drive converter manufacturer and user must apply certain measures.
Perfect functioning of the drive converter can only be guaranteed and the
requirements specified by legislation (89/336/EC) may only be maintained when all
of these measures are observed and fulfilled.
The product standard IEC 1800 - 3 (corresponds to EN 61800 - 3) places
requirements on drive converters with operating voltages less than 1000 V, and
can therefore not be applied to SIMOVERT MV drive converters. The drive
converters, as far as the 3-ph. 400 V AC auxiliary power supply is concerned,
when correctly used, correspond to the following requirements for use in industrial
environments.
