The integrated EMC filters comply with standard IEC 61800-3 for a maximum motor cable length of 10 m/ 32.81 ft for ATV320 ppp M2 p variable speed drives and 5 m/ 16.40 ft for ATV320 ppp N4 p variable speed drives. Additional EMC input filters The additional EMC input filters enable the drives to meet more stringent requirements; they are designed to reduce conducted emissions on the line supply below the limits of standard IEC 61800-3 category C1 or C2 (see page 60883/2). Mounting on ATV320 pppp B Depending on the model, additional EMC filters can be mounted beside or underneath the drive. They act as a support for the drives and are attached to them via tapped holes. Mounting the filter on the side of the drive: 1 ATV320 ppp M2B, ATV320U04N4BU40N4B drives 2 Additional EMC input filters Mounting the filter underneath the drive: 3 ATV320U55N4BU75N4B and ATV320D11N4BD15N4B drives 4 Additional EMC input filters Mounting on ATV320 pppp C Additional EMC filters can be mounted beside or underneath the drive. They act as a support for the drives and are attached to them via tapped holes. Use according to the type of line supply Additional EMC filters can only be used on TN (neutral connection) and TT (grounded neutral) type systems. Standard IEC 61800-3, appendix D2.1, states that on IT systems (isolated or impedance grounded neutral), filters can cause permanent insulation monitors to operate in a random manner. The effectiveness of additional filters on this type of system depends on the type of impedance between neutral and ground, and therefore cannot be predicted. If a machine has to be installed on an IT system, one solution is to insert an isolation transformer and connect the machine locally on a TN or TT system. The radio interference input filters integrated in Altivar 320 drives can easily be disconnected by means of a selector switch without removing the drive.
