CompactRIO cRIO-9066/cRIO-9067 Operating Instructions
Caution
If you use shielded cabling to connect to a C Series I/O module with a
plastic connector, you must attach the cable shield to the chassis grounding terminal
using 1.31 mm
2
(16 AWG) or larger wire. Attach a ring lug to the wire and attach the
wire to the chassis grounding terminal. Solder the other end of the wire to the cable
shield. Use shorter wire for better EMC performance.

Wiring Power to the Chassis
The cRIO-906
x
requires an external power supply that meets the specifications in the
section. The cRIO-906
x
filters and regulates the supplied power and provides
power for all I/O modules. The cRIO-906
x
has one layer of reverse-voltage protection. Complete
the following steps to connect a power supply to the chassis.
1.
Connect the positive lead of the power supply to the V terminal of the COMBICON power
connector shipped with the chassis, and tighten the terminal screw. Figure 13 shows the
terminal screws, which secure the wires in the screw terminals, and the screw flanges,
which secure the power connector on the front panel.

2.
Connect the negative lead of the power supply to the C terminal of the power connector and
tighten the terminal screw.
3.
Install the power connector on the front panel of the chassis and tighten the screw flanges.
Powering On the cRIO-906
x
When you apply power to the cRIO-906
x
, the controller starts up. The Power and Status LEDs
turn on briefly, and then the Status LED turns off. If the LEDs do not behave in this way when
the system powers on, refer to the
Note
After the initial powerup, you must install software on the chassis and
configure system settings in Measurement & Automation Explorer (MAX) as
described in the
section of this document.
