2.8.1 Ferrite Ring Installation
Installation
The ferrite rings are to be installed on the motor wires as close to the
inverter as possible.
Take the ferrite(s) and pass all three motor phases through the center. Use
a wire tie to secure the ferrite(s) to the wire. Note: Do not pass the earth
ground wire through the ferrite(s). Connect the motor wires to the U,
V, and W terminals on the inverter using the specified terminal tightening
torque. When using shielded motor cable, the ferrites are installed on an
unshielded section of the cable before the shielding begins. Terminate the
shield of the cable either to the inverter or directly to the bare metal sub
panel in the control cabinet.
