Installation According to EMC Requirements
The SCM and SCL Series 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 . The SCL Series includes a filter that has been tested
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 when installed in a control cabinet
with a motor cable < 10m . The SCM can be installed to meet these same standards when
used with an appropriately installed external line filter .
EMC
Compliance with EN 61800-3/A11
Installation:
Shielded cable must be used for all control and power cables
and exposed wiring must be kept as short as possible .
