Electrical safety

Electrical safety

The luminaires in this catalogue are designed and produced on the basis of the EN 60598/VDE 0711 standards. The majority of the luminaires bear the relevant test mark on the type plate as well as on the packaging and instructions for use. The other luminaires have been or will be submitted for certification, but the certification and approval procedure is still in progress. We can provide information on the status of the certification procedure at any time. Special orders are produced in accordance with the above set of regulations. All luminaires are subject to continuous monitoring during manufacture and quality assurance. All luminaires are subject to continuous production monitoring and quality inspection.


Safety symbols

The ENEC symbol (European Norms Electrical Certification) is a European test and certification symbol for luminaires and electrical components in luminaires. The number 10 with or without the VDE symbol signifies that the test/certification symbol was issued by the VDE Institute for Testing and Certification.

Surface-mounted luminaires with this symbol are not suitable for direct installation on normally flammable building materials.

Luminaires bearing this symbol are suitable for business premises where dust or fibrous material present a fire hazard due to their limited surface temperatures (VDE 0711 Part 2 - 24).

Recessed luminaires with this symbol are not suitable for direct installation in normally flammable building materials.

Luminaires and power supply units bearing this symbol must not be in direct contact with thermal insulating materials.

The symbol = ... °C in accordance with DIN EN 60 598 / VDE 0711 indicates the permissible ambient temperature at which a luminaire is allowed to be operated. Our luminaires are generally designed for an ambient temperature ta = 25 °C, i.e. for indoor use.

The CE symbol is affixed at the manufacturer’s responsibility and is not a safety symbol. The manufacturer uses it to document conformity with European Union directives.

The number alongside the CE symbol indicates that an inspection and certification body checks compliance with the guidelines.


Protection classes

These classes provide information on a luminaire’s stability in withstanding the penetration of dust, solid bodies and water in accordance with EN 60598/VDE 0711. The respective degree of protection IP (International Protection) is printed on the luminaire as a number system according to IEC 529. You can find the classification of the degrees of protection in accordance with EN 60598 in the table on this page.

Foreign body protection
IP 1x protection against penetration of foreign bodies ≥ 50 mm
IP 2x protection against penetration of foreign bodies ≥ 12 mm
IP 3x protection against penetration of foreign bodies ≥ 2,5 mm
IP 4x protection against penetration of foreign bodies ≥ 1 mm
IP 5x protection against harmful dust deposits
IP 6x protection against dust entry
Water protection
IP x1 protection against drops of water falling vertically
IP x2 protection against drops of water from angles up to 15°
IP x3 protection against showers up to 60°
IP x4 protection against splash water
IP x5 protection against water jets
IP x6 protection against heavy downpours
IP x7 protection against immersion
IP x8...m protection against submersion


Safety classes

Safety class I designates luminaires with an earth connection. In the event of a fault, the power supply is switched off by an overload/residual current protective devices.

Safety class II designates luminaires that have not only functional insulation but also additional protective insulation. Under fault conditions, no dangerous voltage can reach metal parts which can be touched. Many safety class I luminaires are also available in safety class II. Please contact us.

Safety class III designates luminaires operating on extra-low safety voltage. They can be connected only to safety transformers in accordance with EN 61558/VDE 0570, EN 61347/VDE 712 or VDE 0100 Part 410. The transformer must be approved for this type of installation.
