7 .4 INSTALLATION ACCORDING TO EMC REQUIREMENTS
This drive can be installed to meet the European standards for Electromagnetic Compatibility
(EMC) requirements . These requirements govern the permissible electromagnetic emissions
and immunity, both radiated and conducted, of a drive system .
The EMC requirements apply to the final installation in its entirety, not to the individual
components used . Because every installation is different, the recommended installation
should follow these guidelines as a minimum . Additional equipment (such as ferrite core
absorbers on power conductors) or alternative wiring practices may be required to meet
conformance in some installations .
Filter: The input to the drive (or group of drives) must include a filter to reduce the electrical
noise reflected back to the AC Line . To meet the industrial standards set by the EU, EN 61800-
3 for conducted emissions and EN 55011 for radiated emissions to class A compliance, the
drive must be installed with an appropriate filter and a maximum motor cable length of 10m .
