Requirements set out in the Council Directive on the Approximation of the Laws of the Member States relating to Electromagnetic Compatibility (EMC) Directive (2004/108/EEC) and Low Voltage Directive (2006/95/EEC):
The Electromagnetic compatibility directive (2004/108/EC) was created to regulate the compatibility of equipment regarding EMC; it limits the electromagnetic emissions and governs the immunity of equipment.
Electromagnetic Emissions – Limited on equipment so that, when used as designed, they do not disturb radio and telecommunication equipment.
Immunity – Governs the susceptibility of equipment to interference from such equipment as above, when used as designed.
All equipment needs to comply with EMC when put onto the market or put into service to guarantee the free movement of apparatus and to create an acceptable electromagnetic environment in the community territory.
The Low voltage Directive (2006/95/EC) applies to all electrical equipment designed for use with an input/output voltage rating of 50~1000V for alternating current and 75~1500V for direct current.
The Energy related products directive (2009/125/EC) aims to reduce energy consumption and other negative environmental impacts of products.
