Safety Guidelines for Hazardous Voltages
(Screw Terminal and Spring Terminal Products)
If hazardous voltages are connected to the device, take the following precautions. A hazardous voltage is a voltage greater than 42.4 V peak voltage or 60 V DC to earth ground.
You may connect signals which may be floating at hazardous voltages only to the products with screw terminal or spring terminal connectors. Do not connect hazardous voltages to the NI-9375, NI-9470, or to products with DSUB or BNC connectors.
Safety Guidelines for Hazardous Locations
These products have been evaluated as Ex ec IIC T4 Gc equipment and are CCC certified. Each product is suitable for use within ambient temperatures of -40 °C ≤ Ta ≤ 70 °C in either nonhazardous locations or Zone 2 hazardous locations. If you are using the products in Gas Group IIC hazardous locations, you must use the device in an NI chassis that has been evaluated as Ex ec IIC T4 Gc equipment.
Follow these guidelines if you are installing the product in a potentially explosive environment. Not following these guidelines may result in serious injury or death.
