Snap the terminal covers back onto the wiring arms (Figure 7.10). There is
a blank label on each terminal cover and beside the terminal status
indicators on each I/O module. Write terminal designation information on
these labels; it will be useful during system start-up and troubleshooting.

Some I/O modules require shielded-cable connections to help reduce the
effects of electrical noise coupling. Unless specified otherwise, the
recommended cable is Belden 8761. The individual installation data sheet
for each module specifies which connections require shielded-cable and
gives exact wiring connections. In general, however, cable installation
practices must follow these outlined here.

Avoid breaking shields at junction boxes. Many types of connectors for
shielded conductors are available from various manufacturers. If you do
break a shield at a junction box:

connect only category-2 conductors in the junction box
do not strip the shield back any further than necessary to make

a connection

connect the shields of the two cable segments to ensure continuity along

the entire length of the cable
