Measurement Category II is for measurements performed on circuits directly connected to the electrical distribution system. 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 9205 to signals or use Caution for measurements within Measurement Categories III...
Ensure that hazardous voltage wiring is Caution performed only by qualified personnel adhering to local electrical standards. Do not mix hazardous voltage circuits and Caution human-accessible circuits on the same module. Ensure that devices and circuits connected to Caution the module are properly insulated from human contact. When module terminals are hazardous Caution voltage LIVE (>42.4 Vpk/60 VDC), you must ensure...
Special Conditions for Hazardous Locations Use in Europe and Internationally The NI 9205 has been evaluated as Ex nA IIC T4 Gc equipment under DEMKO Certificate No. 03 ATEX 0324020X and is IECEx UL 14.0089X certified. Each NI 9205 is marked II 3G and is suitable for use in Zone 2 hazardous locations, in ambient temperatures of -40 °C ≤...
Furthermore, any changes or modifications to the product not expressly approved by National Instruments could void your authority to operate it under your local regulatory rules. Special Conditions for Marine Applications Some products are Lloyd’s Register (LR) Type Approved for marine (shipboard) applications.
