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 current input, you can input only from the C terminal and one other terminal.
4. Refer to Setting Ranges and Wiring Connections on the I1, I2, and I3 current input terminals.
5. Use the recommended ferrules if you use twisted wires.
6. The K8AK-AW3 is designed to be used in combination with the OMRON K8AC-CT200L Current Transformer (CT).
