12.2 Electromagnetic compatibility
Definition
Electromagnetic compatibility (EMC) is the ability of an electrical installation to function
satisfactorily in its electromagnetic environment without interfering with that environment.
The CPU 1515SP PC2 meets the requirements of the EMC legislation for the European
single market, among other requirements. The prerequisite for this is that the
CPU 1515SP PC2 complies with the specifications and guidelines relating to electrical
configuration.
EMC according to NE 21
The CPU 1515SP PC2 meets the EMC specifications of NAMUR guideline NE 21.
