Installing Remote I/O Cables (continued)
•
The ideal cable installation is a single, unbranched trunk line with
short drop cables and a termination resistor at each end of the trunk.
NOTE:
For installations with five connections or less that have a cable
length between the controller and the most distant RBC less than 30m
(100 feet), any cable configuration can be used. Always use at least one
termination resistor, even with the simplest installation.
Use the following procedures to prepare trunk-line cables for connecting
terminal blocks.
1.
Strip back 1.50 in. (3.8 cm) of the sleeving on both ends of the cable.
NOTE:
You will see three wires when the sleeving is stripped back. Two
wires have color coded insulation jackets and one is bare.
2.
Remove 0.13 in. (0.33 cm) of each color-coded insulation jacket (both
ends) to expose the bare wires.
NOTE:
One wire is already bare.
3.
Install each wire (both cable ends) onto a terminal lug according to
directions provided by the vendor.
NOTE:
The size of the terminal lug depends on the type of terminal block
used. Consult your vendor for the appropriate terminal lug size.
