3.11 Maintaining the EMC Directives

Since January 1996, all manufacturers/companies assembling electrical equipment which have an autonomous function and which

are offered to end users as a single unit, must fulfill the EMC Directive 89/336/EC. Manufacturers/companies assembling electrical

equipment can prove this conformance in three different ways:

1. Self-certification

In this case, the manufacturer makes a declaration that the European Standards, which are applicable for the intended use of

the electrical equipment, are fulfilled. In this case, only the Standards, published in the official journal of the European Union,

can be specified in the manufacturer's declaration.

Technical construction file

A technical construction file can be prepared for the equipment, describing its EMC characteristics. This file must be approved

by a ‘Competent Body’ appointed by the appropriate European government organization. This approach allows the use of

Standards which are still being prepared.

EC type-examination certificate

This approach is only applicable for equipment which operates with radio transmission.

MICROMASTER, MICROMASTER Vector and MIDIMASTER Vector drive units do not have an autonomous function until they

have been connected to other components and devices (e.g. a motor). This is the reason that the basic units are not permitted

to have a CE Mark which would indicate compliance with the EMC Directive.

All of the details regarding the EMC characteristics of the products, if these are installed corresponding to the design/ wiring

guidelines in Section 3.11, are listed in the following tables.

The EMC characteristic is classified into three separate classes which will be subsequently described. It is important to note that the

individual stages are only achieved if the standard (or a lower) pulse frequency is used as well as a motor cable which is a maximum of

25 m long.

Class 1: General industrial environments

Compliance with the EMC Product Standard for motor drive systems EN 61800-3 for use in the Second Environment (industrial

environment)

and for restricted marketing.

EMC Phenomena Standard Level

Emission:

Radiated emission EN 55011 (VDE 0875 Part 11) Level A1 *

Cable-borne emission EN 61800-3 (VDE 0160 Part 100) *

Noise immunity:

Electrostatic discharge (ESD) EN 61000-4-2 (VDE 0847 Part 4-2) 8 kV discharge into air

Burst interference EN 61000-4-4 (VDE 0847 Part 4-4) 2 kV power cable, 1 kV control

Radio frequency electromagnetic field EN 61000-4-3 (VDE 0847 Part 4-3) 26 - 1000 MHz, 10 V/m

· Emission limits are not applicable within a plant or system where no other consumers/loads are connected to the same power

supply transformer.
