3.2.1 Wiring Precautions

1) Be sure to use compensating wire for sensor input wire and connect shield wire to the terminal FG
and ground.
2) Be sure to separate the external input signal of the temperature conversion module from an
alternating current so that surge or induction noise generated from the alternating current could not
effect.
3) When wiring, locating this unit too near from high temperature generating devices or materials or
contacting it with the material like oil can cause short-circuit and occur damage or disorder.
4) When wiring to the terminal block, wiring with high-pressure wire or power supply wire can cause
flow inhibition and cause disorder or malfunction.
3.2.2 Wiring Example
A wiring example of the thermocouple input module is given below.
∗1 ▶ Use compensating wire as cable.
∗2 ▶ Connect shield wire part of compensating wire to the terminal FG and ground.
