8. Control input signal wiring
M3 screws are used for control signal terminals.
Use the proper terminal and securely fasten the screws.
Use wiring that conforms to crimping terminals.
Control signal from the controller (4 – 20 mA, 1 – 5 V, 0 – 10 V, contact, etc.) enters the control input signal terminals (C1, C2, C3).
Be careful of the polarity and make sure noise from strong electric circuits does not get into the wiring.
8-1. 1-to-1 connection with controller
Connection with voltage/current output controller
Adjust controller output with control signal of the PAC18.
In the case of 1-to-1 connection, connect the positive
controller output terminal (+) to C1 and the negative
terminal (-) to C2 as shown in the figure above.

9. Precautions when turning on the power
9-1. Power supply voltage
Use the device with a power supply within 100 to 240 V.
If voltage in excess of the rating is applied, internal components could be damaged. You should therefore be careful of the power supply voltage.
9-2. Power supply frequency
Power supply frequency should be 50/60 Hz.
Power supply frequency is automatically determined, but the device cannot handle sudden frequency change.
Before switching frequency, turn off the device’s power.
Changing power supply frequency with the power on could result in output malfunction causing maximum output.
