4.5.1 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
