Note: Use an isolating 24-VDC power supply, and install the power supply switch on the AC side of the
power supply. If the switch is installed on the 24-VDC side, the inrush current may reach approx. 40
A when the power is turned ON.
 Procedure to Make a 24-VDC Power Cable
The power supply pins are contained in a removable connector. Use the following procedure to
wire the power supply connector. Use a twisted-pair cable with a wire size of AWG28 to
AWG13 (0.08 to 2.6 mm
on the Controller.
The procedure to make the cable is the same as for the 100/200-VAC power supply cable.
Procedure to Make a 100/200-VAC Power Cable (page 2-42)
 When Using the CPU-202 (Model: JEPMC-CP3202-E)
Wrap the power cable twice near the connector and install the ferrite core packaged with the
CPU-202.
