To ensure that the cabinet, filter, and servo amplifier have the same potential, remove or plate paint on the filter surface and
securely ground it to the cabinet.
The same applies to the servo amplifier installation.
Separate the filter input cable (a) from the output cables (b), (c) and (d) as far as possible.
Shorten the wiring ((a), (b), and (c)) between the filter and servo amplifier as short as possible.
(The total of (b) and (c) is 1.5 m or less.)
