Mounting on ATV320ppppB v Depending on the model, additional EMC filters can be mounted beside or underneath the drive. v 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 ATV320pppM2B, ATV320U04N4B…U40N4B drives 2 Additional EMC input filters Mounting the filter underneath the drive: 3 ATV320U55N4B…U75N4B and ATV320D11N4B…D15N4B drives 4 Additional EMC input filters Mounting on ATV320ppppC Additional EMC filters can be mounted beside or underneath the ATV320pppppC drives, except for the ATV320pppS6C drives. They act as a support for the drives and are attached to them via tapped holes. Use according to the type of supply mains v Additional EMC filters can only be used on TN (neutral connection) and TT (grounded neutral) type systems. v 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. v 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. v 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. v The radio interference input filters integrated in Altivar 320 drives can easily be disconnected by means of a selector switch without removing the drive. 2 1 3 4 5 6 7 8 9 10 2 1 3 4 5 6 7 8 9 10 |
