60 Integrated EMC filters Altivar Process drives (except ATV930 ppp M3/M3C) have integrated radio interference input filters in accordance with the EMC standard for variable speed electrical power drive products IEC/EN 61800-3, edition 2, category C2 or C3 in environment 1 or 2, and to comply with the European EMC (electromagnetic compatibility) directive. The integrated EMC filter runs offthe leakage current to ground. The leakage current can be reduced by disconnecting the filter capacitors (please refer to the installation guide on our website In this configuration, the product does not comply with the European EMC directive.

Use according to the type of line supply Use of these additional filters is only possible on TN (neutral connection) and TT (grounded neutral) type systems. Standard IEC/EN 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. If a machine needs to be installed on an IT system, one solution is to insert an isolation transformer and connect the machine locally to a TN or TT system.

If motors are connected in parallel, it is the total length of all cables that should be taken into account. (2) Nominal filter current. (3) Values given depend on the nominal switching frequency of the drive. This frequency depends on the drive rating.
