This document explains how to connect to the NI 9235. 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 9235. The other components in the system might not meet the same safety ratings.
III, or IV. Safety Guidelines for Hazardous Locations The NI 9235 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 9235 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.
This product is intended for use in industrial locations. However, harmful interference may occur in some installations, when the product is connected to a peripheral device or test object, or if the 6 | ni.com | NI 9235 Getting Started Guide...
