Power Supply Wiring

Repeater Units must be supplied with DC power. The procedure for wiring the power supply is the same for all Repeater Units (CS1W-RPT01/02/03).

Use the following procedure to wire the power supply to Repeater Units.

1,2,3... 1. Attach the following crimp terminal to each of the two power lines.

Crimp terminal: AI Series manufactured by Phoenix Contact

Crimp terminal Cable

Insert the cable and then crimp the terminal.

The following specialized tool is available for this purpose:

2.Insert the crimp terminals on the positive and negative power lines into the orange power connectors located near the bottom of the front panel of the Repeater Unit. Insert the positive line in the top and the negative line in the bottom.

3.Use a small, flat-blade screwdriver to fasten the crimp terminals in place.

Note 1. Supply power to the Repeater Unit using a power supply installed specifi- cally for the Repeater Unit. Do not supply power to the Repeater Unit from an I/O power supply, motor power supply, or control power supply.

2.To prevent the power supply from being affected by noise, wire and install the power supply away from power lines and high-voltage lines.

3.Attach special-purpose crimp terminals to the power cables.

4.Do not connect the positive and negative lines to the wrong connectors.

5.The power cable screws should be fastened to a tightening torque of 0.2 N·m.

6.Do not pull on the power cable.

7.Do not bend the power cable past its natural bending radius.
