DIN Rail Mounting

Complete the following steps to mount your NI USB-7846R. You can purchase a DIN rail
mounting clip at 

ni.com

 with part number 781515-01.

1.

Fasten the DIN rail clip to the back of the backpanel wall mount using a #1 Phillips
screwdriver and four machine screws. Tighten the screws to a torque of 0.4 N · m (3.6 lb
· in.).

2.

Clip the bracket onto the DIN rail as shown.
