Guidelines for electromagnetic compatibility (EMC)

4.7.1

Overview

These EMC Guidelines answer the following questions:
● Why are EMC guidelines necessary?
● What types of external interference have an impact on the system?
● How can interference be prevented?
● How can interference be eliminated?
● Which standards relate to EMC?
● Examples of interference-free plant design
The description is intended for "qualified personnel":
● Project engineers and planners who plan system configurations with RFID modules and
have to observe the necessary guidelines.
● Fitters and service engineers who install the connecting cables in accordance with this
description or who rectify defects in this area in the event of interference.
Note
Failure to observe notices drawn to the reader's attention can result in dangerous
conditions in the plant or the destruction of individual components or the entire plant.
4.7.2

What does EMC mean?

The increasing use of electrical and electronic devices is accompanied by:
● Higher component density
● More switched power electronics
● Increasing switching rates
● Lower power consumption of components due to steeper switching edges
The higher the degree of automation, the greater the risk of interaction between devices.
Electromagnetic compatibility (EMC) is the ability of an electrical or electronic device to
operate satisfactorily in an electromagnetic environment without affecting or interfering with
the environment over and above certain limits.
