16.2 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 S7-1500 automation system/ET 200MP distributed I/O system also meets the
requirements of the EMC legislation for the European single market. The prerequisite for this
is that the S7-1500/ET 200MP system complies with the requirements and guidelines relating
to electrical equipment.
EMC in accordance with NE21
The S7-1500 automation system/ET 200MP distributed I/O system meets the EMC
specifications of the NAMUR guideline NE21.
