Communications Cable Wiring

■
This section explains how to prepare and connect the communications cables to connectors for the
DeviceNet Network.
Use the following procedure to prepare and connect the communications cables to the connectors.
Note For connecting of the DeviceNet Communications Card of the Inverter, use DCA1-5C10 Thin
Cables.
Thick Cables cannot be used for this kind of wiring because of the terminal block dimensions.
1.Remove about 30 mm of the cable covering, being careful not to damage the shield weaving un-
derneath. Do not remove more than about 30 mm; removing too much of the covering can result
in short circuits.
2.Carefully peel back the weaving to reveal the signal lines, power lines, and the shielding wire. The
shielding wire will be loose on the outside of the other lines, but it is harder than the weaving.
3.Remove the exposed weaving and the aluminum tape from the signal and power lines. Strip the
covering from the signal and power lines to the proper length for the crimp terminals. Twist together
the wires of each of the signal and power lines.
