9.2 Electromagnetic compatibility
Definition
The electromagnetic compatibility (EMC) is the ability of an electrical device to function in its
electromagnetic environment without influencing this environment.
EMC requirements fulfilled
The ET 200SP HA distributed I/O system also fulfills the requirements of the EMC directive for
the European domestic market.
Requirement
You must ensure that the configuration of the ET 200SP HA corresponds to the specifications
and guidelines for electrical setup.
EMC in accordance with NE21
The ET 200SP HA distributed I/O system fulfills the EMC specifications according to NAMUR
directive NE21.
