After the thermocouple/mV module is properly installed, wire your sensor to the module by
using the shielded thermocouple-extension cable recommended for the type of thermocouple
you are using, or Belden 8761 for non-thermocouple applications.
To wire your sensor to the module, follow these steps.
1. At each end of the cable, strip some casing to expose the individual wires.
2. Trim the signal wires to lengths of 50.80 mm (2 in.); strip about 5 mm (0.20 in.) of
insulation away to expose the end of the wire.
3. At one end of the cable, follow these steps.
a. Twist the drain wire and foil shield together.
b. Bend the drain wire and foil shield away from the cable.
c. Apply shrink wrap.
d. Place the earth ground at the preferred location, based on the type of sensor you
are using.
4. At the other end of the cable, follow these steps.
a. Cut the drain wire and foil shield back to the cable.
b. Apply shrink wrap.
5. Connect the signal wires to the module terminal block and input.
6. Repeat these steps for each channel on the module.
ATTENTION
Be careful when stripping wires. Wire fragments that fall into a module could cause
damage at powerup. Once wiring is complete, be sure that the module is free of all metal
fragments.
