UL EMC Compatibility B introduction This manual was compiled to help system manufacturers using OMRON YASKAWA Motion Control OYMC frequency inverters design and install electrical switch gear It also describes the measures necessary to comply with the EMC Directive The manual s installation and wiring instructions must therefore be followed Our products are tested by authorized bodies using the standards listed below Product standard EN 61800 3 1996 EN 61800 3 A11 2000 B Measures to Ensure Conformity of OYMC Frequency inverters to the EMC Directive OYMC frequency inverters do not necessarily have to be installed in a switch cabinet It is not possible to give detailed instructions for all of the possible types of installation This manual therefore has to be limited to general guidelines All electrical equipment produces radio and line borne interference at various frequencies The cables pass this on to the environment like an aerial Connecting an item of electrical equipment e g drive to a supply without a line filter can therefore allow HF or LF interference to get into the mains The basic countermeasures are isolation of the wiring of control and power components proper grounding and shielding of cables A large contact area is necessary for low impedance grounding of HF interference The use of grounding straps instead of cables is therefore definitely advisable Moreover cable shields must be connected wit
