Wiring for High-Vibration Applications
If an application using the NI 9472/9474 with screw terminal is
subject to high vibration, National Instruments recommends that
you either use ferrules to terminate wires to the detachable
screw-terminal connector or use the NI 9932 backshell kit to
protect the connections. Refer to Figure 5 for an illustration of
using ferrules. Refer to Figure 1 for an illustration of the NI 9932
connector backshell.
