<16 kHz 50 m Class A
2. All motor cables must be shielded cable, or be in grounded metal conduit.
3. All control and signal wiring must use shielded cable or be in grounded metal conduit.
4. Grounding of equipment and cable shields must be solid, with low impedance connections.
5. Ensure that the protective conductor terminal (PE) of the filter is properly connected with the protective
conductor terminal of the drive. The filter must be solidly and permanently connected with the ground
