What to Use

Ring lug

Wire, 2.1 mm

2

 (14 AWG) or larger

Screwdriver, Phillips #2

What to Do

Complete the following steps to ground the NI 9149.

1. Attach the ring lug to the wire.
2. Remove the grounding screw from the grounding terminal on the NI 9149.
3. Attach the ring lug to the grounding terminal.
4. Tighten the grounding screw to 0.5 N · m (4.4 lb · in.) of torque.
5. Attach the other end of the wire to the grounding electrode system of your

facility using a method that is appropriate for your application.

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 2.1 mm

2

 (14 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 NI 9149 to Power

The NI 9149 requires a 9 V to 30 V external power supply. The NI 9149 filters and

regulates the supplied power and provides power for the C Series modules. The

NI 9149 has one layer of reverse-voltage protection.
The following table lists the POWER LED indicators.
