In order to diminish the effects of noise and disturbances, a line filter
should be provided for the 24V DC power supply of the binary inputs and
outputs (e.g. line filter SIFI-B, Order No. B84112-B-.... from Epcos/line
filter NF 1-1 from Phönix Contact). This should be located as close as
possible to the terminal block. The shield connection of the line filter must
be connected to ground through the shortest possible distance.
