Electromagnetic Interference EMI proper installation and wiring methods must be followed to ensure compatibility in each application The type of the electrical noise source or coupling method into a unit may be different for various installations Cable length routing and shield termination are very important and can mean the difference between a successful or troublesome installation Listed are some EMI guidelines for a successful installation in an industrial environment 1 A unit should be mounted in a metal enclosure which is properly connected to protective earth 2 Use shielded cables for all Signal and Control inputs The shield connection should be made as short as possible The connection point for the shield depends somewhat upon the application Listed below are the recommended methods of connecting the shield in order of their effectiveness a Connect the shield to earth ground protective earth at one end where the unit is mounted b Connect the shield to earth ground at both ends of the cable usually when the noise source frequency is over 1 MHz 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 installat
