- COMPLIANCE WITH STANDARDS 

RTS bears the CE mark under European Directive 89/336/EEC as amended by Directive 93/68/EEC on 

electromagnetic compatibility. This European Directive refers to the harmonised generic standards 

EN50081-2 of December 1993 (Electrical Compatibility - Generic Standard for Emissions - Industrial 

Environments) and EN50082-2 of June 1995 (Electromagnetic Compatibility - Generic Standard for 

Immunity - Industrial Environments). These two harmonised generic standards are based on the following 

standards : 

•  EN 55011 of July 1991 : Radiated and conducted emissions 

•  EN 50140 of August 1993 and ENV 50204 : Immunity to radiated electromagnetic fields 

•  EN 61000-4-8 of February 1994: Mains frequency magnetic fields 

•  EN 61000-4-2 of June 1995 : Electrostatic discharge 

•  ENV 50141 of August 1993 : Interference induced in cables 

•  EN 61000-4-4 of June 1995 : Rapid transient currents 

Compliance with the reference standards above implies adherence to the instructions and wiring diagrams 

in the technical documents supplied with the appliances. 

Incorporation in Machinery 

The design of the equipment means it can be used in machinery covered by Directive 89/392/EEC (Machine 

Directive) provided that it is integrated (or incorporated and/or assembled) in accordance with the rules-of-

the-art by the machinery manufacturer and in keeping with the instructions in this booklet.
