3. 3 Never run Signal or Control cables in the same conduit or raceway with AC power lines conductors feeding motors solenoids SCR controls and heaters etc The cables should be run through metal conduit that is properly grounded This is especially useful in applications where cable runs are long and portable two way radios are used in close proximity or if the installation is near a commercial radio transmitter Also Signal or Control cables within an enclosure should be routed as far away as possible from contactors control relays transformers and other noisy components 4 Long cable runs are more susceptible to EMI pickup than short cable runs 5 In extremely high EMI environments the use of external EMI suppression devices such as Ferrite Suppression Cores for signal and control cables is effective The following EMI suppression devices or equivalent are recommended Fair Rite part number 0443167251 RLC part number FCOR0000 Line Filters for input power cables Schaffner FN2010 1 07 Red Lion Controls LFIL0000 6 To protect relay contacts that control inductive loads and to minimize radiated and conducted noise EMI some type of contact protection network is normally installed across the load the contacts or both The most effective location is across the load a Using a snubber which is a resistor capacitor RC network or metal oxide varistor MOV across an AC inductive load is very effective at reducing EMI an
