Chapter 3
Connecting the System

3–4

The communication cable consists of a number of cable segments
daisy-chained together. The total length of the cable segments cannot exceed
1219 m (4000 ft).

When cutting cable segments, make them long enough to route them from
one AIC+ to the next with sufficient slack to prevent strain on the connector.
Allow enough extra cable to prevent chafing and kinking in the cable.

Use these instructions for wiring the Belden #3106A or #9842 cable. (If you
are using standard Allen-Bradley cables, see the Cable Selection Guide on
page 3–8.)
