Caution
If you use shielded cabling to connect to a C Series module with a plastic
connector, you must attach the cable shield to the chassis grounding terminal using
1.3 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.

Connecting the cRIO-9034 to Power
The cRIO-9034 requires a 9 V to 30 V external power supply. The cRIO-9034 filters and
regulates the supplied power and provides power for the C Series modules. The cRIO-9034
has a primary power input, V1, and a secondary power input, V2.
The POWER LED on the cRIO-9034 indicates which power input is in use, as shown in the
following table.
