Wiring Input Devices to the NT4

After the thermocouple module is properly installed in the chassis,
follow the wiring procedure below using the proper thermocouple
extension cable, or Belden 8761 for non-thermocouple applications.

To wire your NT4 module:

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

individual wires.

2. Trim the signal wires to 2-inch lengths. Strip about 3/16 inch

(4.76 mm) of insulation away to expose the end of the wire.

3. At one end of the cable twist the drain wire and foil shield

together, bend them away from the cable, and apply shrink
wrap. Then earth ground at the preferred location based on the
type of sensor you are using (see Wiring Considerations).

4. At the other end of the cable, cut the drain wire and foil shield

back to the cable and apply shrink wrap.

5. Connect the signal wires to the NT4 terminal block and the

input.

6. Repeat steps 1 through 6 for each channel on the NT4 module.
