Measures against inductive noise
In addition to the noise filter described above, you can suppress the inductive noise produced on the
output side by connecting a bundle of wires through a grounded metal conduit.
Moreover, moving the conduit 30 cm or more away from signal lines helps the reduction of inductive
noise.
