Always observe the following precautions when wiring or connecting Noise Filters.
•
Separate input lines from output lines. Do not place input lines and output lines in the same

•
Separate the Noise Filter ground wire from the output lines. Do not place the Noise Filter
ground wire, output lines, and other signal lines in the same duct or bundle them together.
•
Connect the Noise Filter ground wire directly to the grounding plate. Do not connect the
