Installation

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.
