Speed Drive for Fan amp Pumps Applications User Manual 34 Chapter 3 Installation and Wiring Common mistakes in using power line filter 1 Too long power cable The filter inside the cabinet should be located near to the input power source The length of the power cables should be as short as possible 2 The input and output cables of the AC supply filter are too close The distance between input and output cables of the filter should be as far apart as possible otherwise the high frequency noise may be coupled between the cables and bypass the filter Thus the filtering effect becomes ineffective 3 Bad earthing of filter The filter s enclosure must be earthed properly to the metal case of the drive In order to be earthed well make use of a special earthing terminal on the filter s enclosure If you use one cable to connect the filter to the case the earthing is useless for high frequency interference When the frequency is high so is the impedance of cable hence there is little bypass effect The filter should be mounted on the enclosure of equipment Ensure to clear away the insulation paint between the filter case and the enclosure for good earthing contact 3 4 8 EMI of The Drive The drive s operating theory decides that its EMI is unavoidable The drive is usually installed in a metal cabinet the instruments outside the metal cabinet is disturbed by the drive lightly The cables are the main EMI source if you
