Attaching to the NI WSN-3283 Panel Mount Plate

The NI WSN-3283 panel mount kit, NI part number 781075-01, contains a plate for mounting the device 
to a panel. To mount the device, complete the following steps:

1.

Fasten the plate to the device using a number 1 Phillips screwdriver and four 4-20, 5/16 inch length 
thread-forming screws, as shown in Figure 9. The screws are included in the NI WSN-3283 panel 
mount kit.
