Installation
During installation, pass the cable through at least one zero phase reactor. Use a suitable cable type
(insulation class and wire section) so that the cable passes easily through the zero phase reactor. Do not
pass the grounding cable through the zero phase reactor; only pass the motor wire through the zero
phase reactor. With longer motor cables the zero-phase reactor can effectively reduce interference at the
motor output. Install the zero-phase reactor as close to the output of the drive as possible. Diagram A
shows the installation diagram for a single turn zero phase reactor. If the wire diameter allows several
turns, Diagram B shows the installation of a multi-turn zero phase reactor. The more turns, the better the
noise suppression effect.
