Connect the DeviceNet Cable
Follow these procedures when connecting the DeviceNet cable to the
base block.
The required DeviceNet connector is not supplied with the block -
you must purchase it separately. There are three types of connectors
that you can order directly from Rockwell Automation or your local
distributor:
•
1799-DNETCON - 5-position open style connector
•
1799-DNETSCON - 5-position open style connector with locking
screws
•
1799-DNC5MMS - 5-position open style to 12mm connector with
locking screws
Connect the DeviceNet wiring (drop line) to one of the DeviceNet
connectors as shown below. A color-coded wiring diagram is also printed
next to the connector on the left side of the module
Once you have properly wired the drop line to the connector, attach
the connector to the block. If applicable, use the locking screws on
the connector to fasten it to the block.
WARNING
!
If you connect or disconnect the DeviceNet cable
with power applied to this module or any device on
the network, an electrical arc can occur. This could
cause an explosion in hazardous location
installations.
Be sure that power is removed or the area is
nonhazardous before proceeding.
