2004/108/EC, Fixed Installations, and equipment intended for them
2004/108/EC is the 2nd Edition of the EMC Directive, and one of its major differences from the first edition 89/336/EEC is that it includes specific requirements for what it calls “Fixed Installations”, and for equipment that is sold directly for them (and not available to just anyone).
Fixed installations are defined in 2004/108 as: “A particular combination of several types of apparatus and, where applicable, other devices, which are assembled, installed and intended to be used permanently at a predefined location.”
This definition covers all installations from the smallest residential electrical installations through hotels, public buildings, entertainment venues and factories to national infrastructure (e.g. electrical, telephone, road and railway networks) and includes all commercial and industrial installations.
People create all sorts of installations for their own use, for example domestic multi-media installations in private houses. But if they are not doing it professionally, and if they only use apparatus that is compliant with the EMC Directive and use it as intended by its suppliers – then 2004/108 requires no further conformity assessment or other EMC actions.
However, the EC expects professional installers to be competent in all areas that concern compliance with the applicable Directives.
If you create your own fixed electrical installation for producing goods, energy, or services – or if you supply equipment for use in a named fixed installation – then it must comply with the specific requirements in 2004/108/EC from 1st July 2007, and be documented accordingly.
The national laws implementing 2004/108/EC in each EU member state define who is the “Responsible Person” for each fixed installation.
This person is responsible for ensuring that the installation complies with the Directive, and that good EMC engineering practices are used in its construction. They must also document how they have ensured EMC compliance, and keep those documents ready for inspection by the EMC enforcing authorities.
Relying solely on purchasing products that are CE marked will not achieve ‘due diligence’ in compliance with 2004/108/EC, either for equipment manufacturers or for the people responsible for fixed installations.
In the simplest fixed installations, it can sometimes be sufficient to assess the electromagnetic environment, ensure that the EMC characteristics of the purchased equipment are appropriate for operation in that environment, and to follow the supplier’s EMC installation, operation and maintenance instructions.
More complex installations will also require the application of good EMC engineering practices in their design, construction, maintenance and modification.
This training course is specifically designed to provide practical guidance on compliance with the new EMC Directive 2004/108/EC, for persons who are responsible for Fixed Installations, their engineering staff, architects, electrical installers, and designers of equipment intended for named fixed installations.
