Fasten the mounting plate to the surface using the screwdriver and screws that are
appropriate for the surface. The maximum screw size is M4 or number 8.

Optionally, you can use two additional screws to attach the mounting plate to the panel or
wall permanently, preventing the chassis from being removed.

Mounting the cDAQ Chassis on a DIN Rail
Use the DIN rail mounting method if you already have a DIN rail configuration or if you need
to be able to remove the chassis quickly. You can order the NI DIN rail mount kit, part number
781987-01, 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
three M4 × 10 screws. National Instruments provides these screws with the DIN rail mount
kit. Tighten the screws to a maximum torque of 1.3 N ·
m (11.5 lb ·
in.). Make sure the DIN
rail kit is installed as shown in Figure 1-16, with the larger lip of the DIN clip positioned
