Safety Of Machinery In Europe; Machinery Directive - Siemens SINAMICS S120 Function Manual

10.2

Safety of machinery in Europe

The EU Directives that apply to the implementation of products are based on Article 95 of the
EU contract, which regulates the free exchange of goods. These are based on a new global
concept ("new approach", "global approach"):
● EU Directives only specify general safety goals and define basic safety requirements.
● Technical details can be defined by means of standards by Standards Associations that
have the appropriate mandate from the commission of the European Parliament and
Council (CEN, CENELEC). These standards are harmonized in line with a specific
directive and listed in the official journal of the commission of the European Parliament
and Council. Legislation does not specify that certain standards have to be observed.
When the harmonized Standards are observed, it can be assumed that the safety
requirements and specifications of the Directives involved have been fulfilled.
● EU Directives specify that the Member States must mutually recognize domestic
regulations.
The EU Directives are equal. This means that if several Directives apply for a specific piece
of equipment or device, the requirements of all of the relevant Directives apply (e.g. for a
machine with electrical equipment, the Machinery Directive and the Low-Voltage Directive
apply).
10.2.1

Machinery Directive

The basic safety and health requirements specified in Annex I of the Directive must be
fulfilled for the safety of machines.
The protective goals must be implemented responsibly to ensure compliance with the
Directive.
Manufacturers of a machine must verify that their machine complies with the basic
requirements. This verification is facilitated by means of harmonized standards.
IEC 61800-5-2 Adjustable-speed electrical power drive systems Part 5-2 is relevant for the
Machinery Directive: Safety requirements - Functional safety
Within the context of IEC 61508, IEC 61800-5-2 considers adjustable speed electric power
drive systems (PDS), which are suitable for use in safety-related applications (PDS(SR)).
IEC 61800-5-2 places demands on PDS(SR) as subsystems of a safety-related system. This
therefore permits the implementation of the electrical/electronic/programmable electronic
elements of a PDS(SR) taking into account the safety-relevant performance of the safety
function(s) of a PDS.
Manufacturers and suppliers of PDS(SR) can prove to users (e.g. integrators of control
systems, developers of machines and plants etc.) the safety-relevant performance of their
equipment by implementing the specifications stipulated in standard IEC 61800-5-2.
