2-8 Installation and Wiring
Connect the DeviceNet Cable to the 1790D-4R0/T4R0 Base Block
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 5-pin micro male 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
WARNING
ÿ
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.
