Wiring Section 3-2
3-2-4 DeviceNet Wiring
Wire the DeviceNet communications cable as shown in the following diagram.
Stickers are placed on the communication connectors based on the color of
each communications wire. By matching the communications wire colors with
the connector sticker colors, you can check to see if wires are in the correct
locations. The colors of the wires are as follows:
• Turn OFF the power supply to the NE1A-series Controller, to all nodes on
the network, and to communications lines before starting any wiring oper-
ations.
• Tighten the DeviceNet connector to the appropriate torque (0.25 to
0.3 N·m).
• Separate the DeviceNet communications cables from high-voltage/current
lines.
Note Refer to the DeviceNet Operation Manual (W267) for further information on
wiring.
