Safety Guidelines

Operate the NI 9144 chassis only as described in this user guide.

Safety Guidelines for Hazardous Locations

The NI 9144 chassis is suitable for use in Class I, Division 2, Groups A, B,

C, D, T4 hazardous locations; Class 1, Zone 2, AEx nA IIC T4 and Ex nA

IIC T4 hazardous locations; and nonhazardous locations only. Follow these

guidelines if you are installing the NI 9144 chassis in a potentially

explosive environment. Not following these guidelines may result in

serious injury or death.

Caution Do not disconnect the power supply wires and connectors from the chassis unless
