NI 9146 Operating Instructions and Specifications
Mounting the Chassis Directly on a Flat Surface
Using the Mounting Holes
Panel or wall mounting is the best method for applications that are subject
to high shock and vibration. If you do not have the NI 9904 panel mount kit
and do not require the portability that the NI 9904 affords, you can mount
the chassis directly on a flat surface using the mounting holes. Complete
the following steps.
1.
Align the chassis on the surface.
2.
Fasten the chassis to the surface using M4 or number 8 flathead screws,
as shown in Figure 8. National Instruments does not provide these
screws with the chassis.

Caution
Make sure that no I/O modules are in the chassis before removing it from the
surface.
Mounting the Chassis on a DIN Rail
You can order the NI 9912 DIN rail mount kit if you want to mount the
chassis on a DIN rail. You need one clip for mounting the chassis on a
standard 35 mm DIN rail. Complete the following steps to mount the
chassis on a DIN rail.
1.
Fasten the DIN rail clip to the chassis
using a number 2 Phillips
screwdriver and two M4
×
25 screws. National Instruments provides
these screws with the DIN rail mount kit. Tighten the screws to a
maximum torque of 1.3 N
