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.
Among other things, 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.
EM C in accordance with NE21
The S7-1500 automation system/ET 200MP distributed I/O system meets the EMC
specifications of the NAMUR guideline NE21.
Pulse-shaped disturbances
The following table shows the electromagnetic compatibility of the S7-1500 automation
system/ET 200MP distributed I/O system with regard to pulse-shaped disturbances.
