13.2
Electromagnetic compatibility
Definition
Electromagnetic compatibility (EMC) is the ability of an electrical installation to function
satisfactorily in its electromagnetic environment, without affecting that environment.
The S7-1500R/H redundant system also meets the requirements of EMC legislation for the
European Single Market. This is dependent on the S7-1500R/H redundant system complying
with the requirements and guidelines relating to electrical equipment.
EMC in accordance with NE21
The S7-1500R/H redundant system meets the EMC specifications of NAMUR guideline
NE21.
