EMC Installation Guideline – Planning Guide (EMV) – 03.2004 Edition v
Preface
What does EMC mean
EMC is the abbreviation for electromagnetic compatibility. Electromagnetic
compatibility is defined as the characteristic of a piece of electrical equipment to
function satisfactory in a predetermined electromagnetic environment without
influencing this environment unduly.
Who is this manual for
· Project managers creating NC and drive system configurations.
· Installers routing the connection lines.
· Service engineers involved in troubleshooting and fault elimination.
Machine manufacturers
The notes indicated in Chapters 2, 4, 5, 6, 7, 9, 10, 11 are primarily directed
towards machine manufacturers, who can influence or change the functional
behaviour of the complete system by means of the described measures.
Subject matter of this manual
You receive the following information in this Guideline:
· Why are EMC guidelines necessary?
· Which interference sizes have an effect on the control from outside
(interference sink)?
· How can EMC malfunctions be prevented?
· Which practical application examples are available for a trouble-free system
structure?
· What must be considered when handling electrostatically sensitive
assemblies?
· How can a malfunction caused by a deficient EMC be eliminated?
Objectives
These guidelines are not, and do not aim to be, a textbook for EMC. The purpose
of these guidelines is to provide the practical person with instructions for securing
the EMC.
Compliance with these EMC guidelines are necessary to
a) achieve a minimum noise immunity of the accessories in such a way that they
function perfectly in a harsh industrial environment and
b) to not have an undue impact on the environment in terms of radio interference.

vi EMC Installation Guideline – Planning Guide (EMV) – 03.2004 Edition
These guidelines also describe the necessary measures according to the
European Union (EU) directives for compliance with the EMC law or the EMC
guidelines.
In installation locations with extremely high interference levels, malfunctions can be
caused despite compliance with these EMC Guidelines, although it is very unlikely.
What prior knowledge is required?
Apart from these EMC Guidelines, international and country-specific safety
regulations continue to apply.
Good knowledge of the relevant standards and EU regulations is necessary, so
that the safety concerns are not impaired when implementing these EMC
Guidelines. The implementation of these EMC Guidelines must be performed by
qualified personnel.
Qualified personnel
All persons who are entrusted with the installation, assembly, commissioning and
operation of the product and who possess the necessary qualifications are to be
considered to be qualified personnel.
The authorization to connect circuits and devices in accordance with the approved
standards of electrical engineering, to bring them into operation and to remove
them from operation applies as a particular qualification.

Safety and warning concept
The following safety and warning information is used in this document.
Explanation of symbols used:
!
Danger
Indicates an imminently hazardous situation which, if not avoided, will result in
death or serious injury or in substantial property damage.
!
Warning
Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury or in substantial property damage.
!
Caution
This symbol (with a warning triangle) indicates that minor injury or damage to
property may result if proper precautions are not taken.
Caution
Used without safety alert symbol indicates a potentially hazardous situation
which, if not avoided, may result in property damage.
Notice
Used without the safety alert symbol indicates a potential situation which, if not
avoided, may result in an undesirable result or state.
