Terminal Diagram

Note: 1.

Do not connect anything to terminals that are shaded in gray.

2.

There is no polarity for the DC power supply input.

3.

For the voltage input, you can input only from the C terminal and one other terminal.

4.

Refer to 

Setting Ranges and Wiring Connections

 for information on the V1, V2, and V3 voltage input terminals.
