general standards for any product to guarantee electromagnetic compatibility by restricting the maximum level of emission of the product and its minimum immunity to external EMI. The manufacturer of any transportable product must declare the conformity of the product with the standards of the EU. The product has to be marked with the CE-sign to certify its compliance with the EMC and other directives to the consumer.
As far as electrical installations are concerned the declaration of conformity and CE-sign are not required, however compliance to the standards of the EU directive has to be guaranteed. This is the task of those responsible for the design, engineering and construction of the electrical installation. There are routes to guarantee and verify the compliance. The first is to use EMC qualified modules, which are installed by EMC trained personnel. The second is to use any available modules and certify the EMC compliance of the installation by measurement by an EMC laboratory or a notified body. In any case, the planner has to assert compliance with the EMC standards of the EU directive by appropriate documents. Additionally the ‘manufacturer’ of the installation must provide clear instructions for operation and maintenance in accordance with the Annex III of the EU directive. These instructions must give information on intended conditions of use, installation, assembly, adjustment, commissioning, use and maintenance. Where necessary, warnings about limitations of use must be included.
The safest way to guarantee the compliance of an electrical installation of a building may be to obey the following rules:
