DeviceNet Thick Cable
Thick cable consists of two shielded pairs twisted on a common axis with a drain wire in the center
covered with an overall braid shield and is commonly used as trunk line when length is important.
The thick cable specified for DeviceNet network connections consists of:
• One twisted signal pair (#18): blue/white
• One twisted power pair (#15): black/red
• Separate aluminized Mylar shields around power pair and signal pair
• Overall foil/braid shield with drain wire (#18): bare
DeviceNet Thin Cable
Thin Cable is smaller and more flexible than Thick Cable. It is commonly used for drop lines, but
can also be used, for shorter distances, as trunk line.
The thin cable specified for DeviceNet network connections consists of:
• One twisted signal pair (#24): blue/white
• One twisted power pair (#22): black/red
• Separate aluminized Mylar shields around power pair and signal pair
• Overall foil/braid shield with drain wire (#22): bare

Remove power and wait for all LEDs to go out
before making DeviceNet and control terminal
connections. Use standard DeviceNet thin or
thick cable when connecting to DeviceNet
terminals.
Remove the front cover and connect the
DeviceNet communication wires on the
quick-disconnect screw terminal on the
Drive (see page 11, Cable Installation).
Control wiring should be sized 16 to 20 AWG.
Control wiring should be shielded, with the
shield wire connected to the ground terminal ,
which is located towards the left side of the
aluminum heat sink.
