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.

Preface

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.
