• Do not make any mistake in polarity when supply DC power to the K3NH.
• Do not wire power lines alongside the signal lines of the K3NH in order to pre-
vent against noise interference.
• Wire the terminal block with crimp terminals
• Tighten each screw to a torque of 0.78 N S m (8 kgf S cm).
Apply 100 to 240 VAC or 12 to 24 VDC to terminals 8 and 9.
Connect a platinum resistance thermometer to terminals 2, 3, and 4 or a thermo-
couple to terminals 3 and 4. The terminals used vary with the input type range as
