This document explains how to connect to the NI 9214. Before you begin, complete the software and Note hardware installation procedures in your chassis documentation. The guidelines in this document are specific to Note the NI 9214. The other components in the system might not meet the same safety ratings.
This category refers to local-level electrical distribution, such as that provided by a standard wall outlet, for example, 115 V for U.S. or 230 V for Europe. Do not connect the NI 9214 to signals or use Caution for measurements within Measurement Categories III or IV.
Safety Guidelines for Hazardous Locations The NI 9214 is suitable for use in Class I, Division 2, Groups A, B, C, D, T4 hazardous locations; Class I, Zone 2, AEx nA IIC T4 and Ex nA IIC T4 hazardous locations; and nonhazardous locations only.

Zone 2 hazardous locations, in ambient temperatures of -40 °C ≤ Ta ≤ 70 °C. If you are using the NI 9214 in Gas Group IIC hazardous locations, you must use the device in an NI chassis that has been evaluated as Ex nC IIC T4, Ex IIC T4, Ex nA IIC T4, or Ex nL IIC T4 equipment.
In order to meet the EMC requirements for Caution marine applications, install the product in a shielded enclosure with shielded and/or filtered power and input/output ports. In addition, take precautions when designing, selecting, and installing measurement probes 8 | ni.com | NI 9214 Getting Started Guide...
