Noise Filter (Power Supply Line Filter)
A noise filter is a component which has an effect on conducted noise. Although installing a noise filter on the power supply cable is not
mandatory, doing so can suppress a larger amount of noise. (The noise filter is generally effective for reducing conducted noise in the band
of 10 MHz or less.) Use the filters equivalent to the following filters.
The precautions when attaching a noise filter are described below.
• Do not run the input and output cables of the noise filter together. Doing so inducts the output side noise into the input side cable where
noise has been eliminated by the noise filter.
• Connect the ground terminal of the noise filter to the control panel with the shortest cable as possible (approx. 10 cm (3.94 inch.)).
