  • Page 4: Emc And Lvd Conformity

    EMC and LVD Conformity IMO Jaguar VXS Inverters carrying the suffix -EN as part of their model number conform to EN 60 947-1:1992, Emissions to EN50081-1 and -2 and Immunity to EN50082-1 and -2, and therefore meet Directive 89/336/EEC relating to Electromagnetic Compatibility. Additionally, they also comply with DIN VDE 0160/1988 for Over Voltage Category II, Pollution Degree 2, and hence conform to the protection requirements of Council Directive 73/23/EEC, Low Voltage Directive.
