Preparing DeviceNet Communications Cables

1,2,3...
The methods used for preparing DeviceNet communications cables to be
connected for DeviceNet communications are explained here.
For details on the DeviceNet Network, such as supplying the DeviceNet com-
munications power and grounding the DeviceNet Network, refer to the
DeviceNet Operation Manual (W267). The wiring methods for Thin Cable are
described in this section.
Use the following procedure to prepare and connect the communications
cables to the connectors.
1. Remove approximately 30 to 80 mm of the cable covering, being careful
not to damage the shield mesh underneath. Do not remove too much cov-
ering or a short circuit may result.
Approx. 30 to 80 mm
(Remove as little as possible.)
2. Carefully peel back the shield mesh to reveal the signal lines, power lines,
and the shield wire. The shield wire is slightly harder to the touch than the
mesh.
3. Remove the exposed mesh and the aluminum tape from the signal and
power lines. Strip the covering from the signal and power lines to the prop-
er length for the crimp terminals. Twist together the wires of each of the sig-
nal and power lines.
Strip to match the
crimp terminals.
4. Attach crimp terminals to the lines and then cover any exposed areas with
vinyl tape or heat-shrink tubing.
Orient the connector properly, then insert each of the signal lines, power
supply lines, and the shield wire into the connector holes from the top in
the order red, white, shield, blue, black, as shown in the following diagram.
The DeviceNet-compatible Controllers are equipped with screwless con-
nectors, so the cables do not need to be secured with screws as with pre-
vious DeviceNet communications connectors. With the orange lever
pushed down, insert each of the lines into the back of the holes.
Release the orange lever and gently tug on each line to check that it is con-
nected properly.
