Wiring for High-Vibration Applications
If an application 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 9939 backshell
kit to protect the connections. Refer to Figure 2 for an illustration.
