  • Page 51 Forewords In EU, the EMC Directive became mandatory on 1. January 1996. To show the conformity, CE marking is required to apply on products. As it is known, the CE mark is primarily for final products for users. FANUC’s CNCs and amplifiers are essentially parts of machine tools, nevertheless, cons

Consequently, a manufacturer can declare, by themselves, product conformity to the EMC Directive by indicating that the product meets relevant harmonized standards. * The generic immunit
