Mounting the Chassis Directly on a Flat Surface Using the
Mounting Holes
If you do not have the NI 9904 panel mount kit and do not require the portability of
the NI 9904, you can mount the chassis directly on a flat surface using the mounting
holes.
1. Align the chassis on the surface.
2. Fasten the chassis to the surface using M4 or number 8 flathead screws, as
shown in the following figure. National Instruments does not provide these
screws with the chassis.

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 to mount the NI 9146 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 × 16 screws. NI provides these screws with the DIN rail mount kit.
