Wiring
NOTE:The wiring label on the front of the module shows the cable
colors.
1. Connect the DeviceNet cable to the removable connector.
2. Insert connector into mating connector on DeviceNet adapter
module.
3. Connect +24V dc input to the left side of the lower connector,
terminal E.
4. Connect 24V common to the left side of the upper connector,
terminal D.
5. Connections G and F are used to pass 24V dc power and common
to the next module in the series (if required).
6. Set the network address using the 2-position thumbwheel switch B.
Valid settings range from 00 to 63. Press either the + or - buttons to
change the number.
