Installation tips:
Installation location: The best location for filter installation should be at the entrance of the power cord to shorten the length of the input wire in the chassis and reduce spatial coupling of radiated interference
Grounding: of the filter Grounding must be good. For filters with metal shells, the shell must be connected to the equipment chassis with low impedance, that is, the shell must be in conductive contact with the chassis panel and connected to the ground wire
Wiring of the input and output ends of the filter: input line of the filter , The output lines must be kept apart, and avoid running parallel lines to avoid coupling between the input cable and the output cable and bypassing the filter, causing the filter to fail.
