2 EMC Installation Guideline

2.1 Introduction

2.1.1

General

EMC stands for "Electromagnetic Compatibility" and, according to the EMC Directive, describes "the capability of a
device to function satisfactorily in an electromagnetic environment without itself causing intolerable interference for
other devices in the environment".
The growing use of power electronics devices in combination with microelectronics devices in increasingly-complex
systems has meant that electromagnetic compatibility has become an extremely important issue when it comes to
ensuring that complex systems and plants function without any problems.
For this reason, the question of electromagnetic compatibility must be taken into account as early as the planning
phase for devices and systems. This involves, for example, defining EMC zones, establishing which types of cables
are to be used and how these are to be routed, as well as providing filters and other interference suppression
measures where appropriate.
This chapter is designed to help planning and assembly personnel of OEM customers, cabinet builders, and system
integrators to ensure compliance with the regulations of the EMC Directive when SINAMICS drives are used in
systems and plants.
The modular concept of SINAMICS allows for a wide range of different device combinations. A description of each
individual combination cannot, therefore, be provided here. As such, this section aims to outline some fundamental
principles and generally applicable rules that should be taken into account to build up any device combination in such
a way that it is "electromagnetically compatible". To clarify descriptions, some examples for typical applications are
provided with explanations at the end of this chapter.
The devices described in this document (SINAMICS G130, G150, S120 Chassis, S120 Cabinet Modules, and S150)
are not classified as "devices" in the context of the EMC Directive, but as "components" designed to be integrated in
a complete system or plant. To facilitate understanding, however, the generally accepted term "devices" will be used.
2.1.2

EC Directives

EC Directives are published in the Official Journal of the European Union and must be incorporated into national
legislation of EU member states, with the aim of facilitating free trade and movement of goods within the European
Economic Area. EC Directives published and their implementation as a part of national legislation thus form the basis
for legal proceedings within the European Economic Area.
Two European Directives relating to variable-speed electric low-voltage drive systems have been published:
·
Low-Voltage Directive 2006/95/EC
(Legal regulations for electrical equipment in EU member states)
·
EMC Directive 2004/108/EC
(Legal regulations for electromagnetic compatibility in EU member states)
This section describes the EMC Directive in more detail.
2.1.3

CE marking

The CE marking is a declaration of conformity to all EC Directives to be implemented. Responsibility for attaining the
CE marking lies with either the manufacturer or the person/company who launched the product or system. The
prerequisite for CE marking is a self-confirmation (or declaration) of the manufacturer indicating that the device in
question is conform to all applicable European standards. This declaration (factory certificate, manufacturer's
declaration, or declaration of conformity) must only include standards that are listed in the Official Journal of the
European Union.
