Rockwell Automation 1794-ACN15_ACN15K_ACNR15_ACNR15XT, Series D FLEX I/O ControlNet Adapter Modules - Manual (Page 4)

4 FLEX I/O ControlNet Adapter Modules
Publication 1794-IN128E-EN-P - March 2011
Connecting Wiring
1. Connect the ControlNet network cable to connector, terminal A.
2. For 1794-ACNR15, 1794-ACNR15XT only: Connect the redundant
ControlNet network cable to connector B.
3. Connect +V DC power to the left side of the lower connector, terminal D.
4. Connect -V common to the left side of the upper connector, terminal C.
5. Connections E and F are used to pass +V DC power (F) and -V common
(E) to the next module in the series (if required).
6. Set the network address using the selection dials G. Valid settings range
from 01…99.
Indicators
The module has LED indicators to specify its status and aid the user in
troubleshooting.
Specifications
WARNING
If you connect or disconnect the ControlNet cable with power applied
to this module or any device on the network, an electrical arc can
ocur. This could cause an explosion in hazardous installations. Be
sure that power is removed or the area is nonhazardous before
proceeding.
WARNING
If you connect or disconnect wiring while the field side power is on,
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.
ATTENTION
• When connecting wiring, torque terminal screws C, D, E and F
to 0.8 Nm (7 lb-in).
• Power wiring must be less than 10 meters (32.8 ft) in length.
• Do not wire more than 2 conductors on any single terminal.
