Appendix G – Regulatory Information 05/2008 Danaher Motion136 S200-VTS Product ManualG.9 EMC Compliance with EN61800-3Use in a Domestic EnvironmentWARNINGThe products covered in this manual are of the restricted sales distributionclass according to IEC 61800-3. In a domestic environment this productmay cause radio interference in which case the user may be required totake adequate measures.CAUTIONBecause applications differ, it is impossible for the drive manufacturer toguarantee machine EMC compliance. In some applications, it may benecessary for the machine builder to incorporate more EMC mitigationtechniques than Danaher Motion had to use in the EMC test setups.General Suggestions to Improve Machine EMC PerformanceUse Danaher Motion cables – Danaher Motion cables have been designed with EMCconsiderations in mind. Because subtle differences in cable construction can cause dramaticchanges in EMC performance use of Danaher Motion's motor power and feedback cables isrecommended.When joining or splicing sections of cable, be sure to maintain the integrity of the cableshield along the entire length of the finished cable.Separate cables according to type - AC Mains input, motor power and signal cables shouldbe separated from each other by at least 100 mm (4 in) to avoid cross coupling between them.If cables of different types have to cross, they should do so at a 90° angle.Route wiring close to machine frame - It is a good practice to run wires along the machineframe (local ground) whenever practical, this couples some high frequency noise/signals thatcould otherwise be troublesome directly to the local ground.Remove paint from all drive, filter, and cable clamp mounting locations.Add clamp-on ferrites to cables – Adding clamp-on ferrites to noisy cables can reduceemissions by absorbing RF energy before it is radiated.Use the appropriate line filter – A line filter is required for CE applications, more informationon line filter selection can be found in D.10Add a balun to the motor power cable – adding a balun in series with the U, V and Wphases of the motor power cable can attenuate both conducted and radiated emissions.Ensure that cables shields have a good RF ground – more information on this can be foundin D.10.
