Any machine or system that wants to be brought onto the market in the EU and associated countries must bear a CE marking issued by the manufacturer himself. With this marking, the manufacturer guarantees that his product complies with all applicable legal and technical requirements. It is a matter of safety. For humans and machines.
In Europe, the Machinery Directive 2006/42/EC and the Low Voltage Directive 2014/35/EU set minimum standards for safety and occupational health requirements. The details and designs for implementation are defined in separate technical specifications, known as harmonising standards. One of these harmonising standards is IEC 60204-1, which specifies the requirements for the electrical equipment of machines. It applies to electrical, electronic, and programmable electronic equipment as well as to groups of networked machines, including control cabinet constructions.
