Rockwell Automation 1794-AENT FLEX I/O EtherNet/IP Adapter Module Installation Instructi - Manual (Page 4)

4 FLEX I/O EtherNet/IP Adapters Installation Instructions
Publication 1794-IN082C-EN-P - October 2007
Before installing the new adapter, notice the notch on the
right rear of the adapter. This notch accepts the hook on
the terminal base unit. The notch is open at the bottom.
The hook and adjacent connection point keep the
terminal base and the adapter tight together, reducing the
possibility of a break in communication over the
backplane.
7. Complete the adapter mounting as shown below.
8. If the adapter does not lock in place, use a
screwdriver or similar device to move the locking
tab down while pressing the adapter flush onto the
DIN rail: releasing the locking tab to lock the
adapter in place.
If necessary, push up on the locking tab to lock.
9. Reinstall the module in the adjacent terminal base
unit.
Connect Wiring
1. Connect the Ethernet network cable to the RJ45
connector (A) on the underside of the adapter.
2. Connect 24V common to the left side of the upper
connector, terminal B.
3. Connect +24V dc input power to the left side of
the lower connector, terminal C.
4. Use connectors D and E to pass 24V common
(D)
and 24V dc power (E) to the next module in
the series.
WARNING
If you connect or disconnect the communication
cable with power applied to the adapter 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.

Push down and in at the same time
to lock the adapter to the DIN rail. When the adapter is locked onto the DIN

IMPORTANT
We recommend connecting the module to the
network via a 100 MB full-duplex switch, which will
reduce network collisions and lost packets, and
increase bandwidth. For detailed Ethernet
connection information, see these publications:
• Ethernet/IP Performance and Application Guide,
publication ENET-AP001
• Ethernet/IP Media Planning and Installation
Guide, publication number ENET-IN001
• Precautions to Increase the Noise Immunity of
the 1794-AENT FLEX I/O Ethernet/IP Adapter
System, KnowBase Technote ID 42604
IMPORTANT
Do not wire more than 2 conductors on any single
terminal.
When connecting wiring, torque terminal screws B,
C, D, and E to 0.8 Nm (7 lb-in).
