• CP1E CPU Units with 30 or 40 I/O Points or Expansion I/O Units with 32 or 40 I/O Points
• CP1E CPU Units with 20 I/O Points, Expansion I/O Units with 8, 16, or 20 I/O Points, and Expan-
sion Units
Whenever possible, route I/O wiring through wiring ducts. Install the ducts so that it is easy to wire the
I/O Units through the ducts. It is handy to have the ducts at the same height as the Racks. Use mount-
ing bases if necessary to adjust the heights.
