Electromagnetic Compatibility - Siemens SIMATIC S7-1500/ET 200MP System Manual

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.
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.
