Caution NI 9997 Getting Started Guide | © National Instruments | 3 Safety Guidelines for Hazardous Voltages If hazardous voltages are connected to the module, take the following precautions. A hazardous voltage is a voltage greater than 42.4 Vpk or 60 VDC to earth ground. Ensure that hazardous voltage wiring is performed only by qualified personnel adhering to local electrical standards. Caution Caution Do not mix hazardous voltage circuits and human-accessible circuits on the same module. Make sure that devices and circuits connected to the module are properly insulated from human contact. Caution When module terminals are hazardous voltage LIVE (> 42.4 Vpk/60 VDC), you must ensure that devices and circuits connected to the module are properly insulated from human contact. You must use Connector Backshell Kit 783804-01, as shown in Figure 1, to ensure that the terminals are not accessible. Caution 4 | ni.com | NI 9997 Getting Started Guide Figure 1. Connector Backshell 783804-01 Safety Guidelines for Hazardous Locations The NI 9997 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. Follow these guidelines if you are installing the NI 9997 in a potentially explosive environment. Not following these guidelines may result in serious injury or death. NI 9997 Getting Started Guide | © National Instruments | 5 Do not disconnect I/O-side wires or connectors unless power has been switched off or the area is known to be nonhazardous. Caution Do not remove modules unless power has been switched off or the area is known to be nonhazardous. Caution Substitution of components may impair suitability for Class I, Division 2. Caution For Division 2 and Zone 2 applications, install the system in an enclosure rated to at least IP54 as defined by IEC/EN 60529. Caution Special Conditions for Hazardous Locations Use in Europe This equipment has been evaluated as Ex nA IIC T4 Gc equipment under DEMKO 12 ATEX 1202658X. Each module is marked II 3G and is suitable for use in Zone 2 hazardous locations, in ambient temperatures of -40 °C ≤ Ta ≤ 70 °C. If you are using the NI 9242 in Gas Group IIC hazardous locations, you must use the device in an NI chassis that has been evaluated as AEx nA IIC T4, EEx nC IIC T4, Ex nA IIC T4, or Ex nL IIC T4 equipment. 6 | ni.com | NI 9997 Getting Started Guide Caution You must make sure that the transient disturbances do not exceed 140% of the rated voltage.
