Installation & Connection 7-16AC10 InverterNote: The motor cable should be screened and earthed at the drive side, if possible, themotor and drive should be grounded separately; Motor cable and control cable should be shielded. The shield must be earthed andavoid entangling at cable end to improve high frequency noise immunity. Assure good conductivity among plates, screw and metal case of the drive; use tooth-shape/spring washer and conductive installation plate.7.7.7 Application of Power Line FilterPower source filter should be used in the equipment that may generate strong EMI or theequipment that is sensitive to the external EMI. The power source filter should be a two-waylow pass filter through which only 50Hz current can flow and high frequency current should berejected.Function of Power Line FilterThe power line filter ensures the equipment can satisfy the conducting emission andconducting sensitivity in EMC standard. It can also suppress the radiation of the equipment.Common mistakes in using power cable filter:1. Power cable too longThe filter inside the cabinet should be located near to the input power source. The length of thepower cables should be as short as possible.2. The input and output cables of the AC supply filter are too closeThe 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.This will make the filter ineffective.3. Bad Grounding of filterThe filter’s enclosure must be earthed properly to the metal case of the drive. In order to beearthed well, make use of a special grounding terminal on the filter’s enclosure. If you use onecable to connect the filter to the case, the grounding 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 theinsulation paint between the filter case and the enclosure for good grounding contact.
