This section describes how to connect the communication cable to the DN91.
The DN91 DeviceNet connector is shown in the diagram above. The side of the
connector is color-coded with the corresponding cable lead colors.
Connect the communication cable, ensuring that each cable lead color matches the
marking on the connector.
(2) Grounding the network
DeviceNet network is to be grounded at a single point.
And select a point for grounding in the vicinity of the center of the network.
Connect a cable shield (drain wire) to the ground of the power supply unit for Class-D
(Class-3) grounding.
If the network contains multiple power supply units, ground a unit that is positioned near
the center of the network and do not ground at any other positions. When using multiple
power supply units, use power taps.
