Note1) Check the power supply voltage before installation.

Note2) Connect the I/V unit (250Ω resistor) (accessory) between the terminal and in case of current input.
Note3) Tighten the terminal screw securely with fastening torque of 0.4N·m.
Note4) When the 10th digit of the code symbol is "C", "A", or "B", connect the power according to the connection
diagram of 24VAC/24VDC power supply. Input of power of 30VAC/30VDC or more will damage the instrument.
