• For details of Fieldbus connection and wiring work, refer to “Fieldbus Technical Information” (TI 38K03A01-
01E).
• The clamp filter part number and method of attachment are the same as for that used in the ACM11
Communications Module. Mount it as close as possible to the terminals, as illustrated in the figure below.
There is a gap between the inside of the core and outside of the cable, so secure the cable by clamping the
cable fastener over the cable coating.
