11.4 Electromagnetic Compatibility
Electromagnetic compatibility
All manufacturers/assemblers of electrical apparatus which "performs a complete intrinsic
function and is placed on the market as a single unit intended for the end user" must comply
with the EMC directive.
There are three routes for the manufacturer/assembler to demonstrate compliance:
Self-certification
This is a manufacturer's declaration that the European standards applicable to the electrical
environment for which the apparatus is intended have been met. Only standards that have
been officially published in the Official Journal of the European Community can be cited in
the manufacturer's declaration.
Technical construction file
A technical construction file can be prepared for the apparatus 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
that are still in preparation.
EMC Standards
The SINAMICS G120 drives have been tested in accordance with the EMC Product
Standard EN 61800-3:2004.
EMC Emissions
Note
Install all drives in accordance with the manufacturer's guidelines and in accordance with
good EMC practices. See also: EMC-compliant connection (Page 36).
Use screened cable type CY. The maximal cable length is 25 m.
Do not exceed the default switching frequency 4 kHz.
