AC Line Filters
The AC line filters used during Control Techniques’ compliance testing are listed below.
These filters are capable of supplying the drive input power to the specified drive under
maximum output power conditions.
Alternately, Control Techniques has also seen good results with the following line filters:
AC Line Filter Installation Notes
• EMC criteria can be met in installations where multiple drives are supplied through a
single filter, however, it is the installers responsibility to verify EMC compliance.
Questions on this subject should be directed to the filter manufacturer.
• It is critical that you keep the filter inputs routed away from any electrical noise sources
to prevent noise from being induced into them and carried out of the enclosure.
Cable to Enclosure Shielding
Shielded motor, feedback, serial communications and external encoder cables were used for
Control Techniques’ compliance testing and are necessary to meet the EMC requirements.
Each cable shield was grounded at the enclosure wall by the type of grommet described earlier
and shown in the Figure 2.
