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 12 mm (0.47 in.) connector
with locking screws
Connect the DeviceNet wiring (drop line) to one of the DeviceNet connectors as shown
in
. A color-coded wiring diagram is also printed next to the connector on the
left side of the module.
Figure 6 - DeviceNet Wiring
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.
