Separate the noise filter ground wire from the output lines.
Do not accommodate 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 ground plate.
Do not connect the noise filter ground wire to other ground wires.
If a noise filter is located inside a control panel, first connect the noise filter ground wire and the
ground wires from other devices inside the control panel to the ground plate for the control panel,
then ground the plates.
The ground wire
can be close to
input lines.
