6.After aligning the positions of the DeviceNet Communications Unit connector and the Inverter con-
nector, push the frames of the Inverter and the Unit together until they click.
7.Tighten the fixing screws on the upper part of the DeviceNet Communications Unit, to the mount-
ing base attached in step 4.
8.Wire the communications cables, and set the Unit’s node address.
9.Attach the Operator and the terminal cover to the front side of the DeviceNet Communications
Unit, and secure them by tightening the screw in the center.

Connecting Communications Cables
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 Unit 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.
