Preparing and Wiring the Cables

To prepare and connect cable leads and drain wires, follow these
steps:

1. At each end of the cable, strip some casing to expose individual

wires.

2. Trim signal wires to 5-inch lengths beyond the cable casing.

Strip about 3/16 inch (4.76 mm) of insulation to expose the ends
of the wires.

3. At the module end of the cables:

extract the drain wire and signal wires

remove the foil shield

bundle the input cables with a cable strap

4. Connect pairs of drain wires together:

Channels 0 and 1

Channels 2 and 3

Channels 4 and 5

Channels 6 and 7

Keep drain wires as short as possible.

5. Connect the drain wires to the shield inputs of the terminal

block if appropriate for thermocouple used.

Channel 0 and 1 drain wires to pin 5

Channel 2 and 3 drain wires to pin 10

Channel 4 and 5 drain wires to pin 15

Channel 6 and 7 drain wires to pin 20
