*1: The wiring used for analog input should adopt the connection cable or shielding cable of
thermocouple temperature sensor J-type / K-type / R-type / S-type / T-type / E-type / N-type
and should be separated from other power cable or wirings that may cause interference.
The screw torque of the terminal should be 1.95 kg-cm (1.7 in-lbs).
*2: Please connect the
terminal on both the power module and DVP08TC-H2 to the system
earth point and ground the system contact or connect it to the cover of power distribution
cabinet.
*3: Terminal SLD is a grounding location for noise suppression.
Note: DO NOT wire empty terminal. Use 60/75°C copper conductor only.
