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.

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.
