Note Some NI C Series modules offer two types of spring terminal connectors: push-in spring terminal and spring terminal. The black/orange push-in spring terminal connectors do not require a tool for signal connection; push the wire into the terminal when using solid wire or stranded wire with a ferrule, or by pressing the push button when using stranded wire without a ferrule. The black spring terminal connectors require a flathead screwdriver with a 2.3 mm × 1.0 mm (0.09 in. × 0.04 in.) blade for signal connection; insert the screwdriver into a spring clamp activation slot to open the corresponding connector terminal, press a wire into the open connector terminal, and then remove the screwdriver from the activation slot to clamp the wire into place.

Safety Guidelines

Operate the product only as described in this document.

  • 1378 Caution—This icon denotes a caution, which advises you to consult documentation where this symbol is marked.
  • 1378 Hazardous Voltage—This icon denotes a warning advising you to take precautions to avoid electrical shock with the product.
    • Caution Do not operate this product in a manner not specified in this document. Product misuse can result in a hazard. You can compromise the safety protection built into the product if the product is damaged in any way. If the product is damaged, return it to NI for repair.

    Safety Guidelines for Hazardous Voltages (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 signals which may be floating at hazardous voltages to the products with DSUB or LEMO connectors.

    Caution Ensure that hazardous voltage wiring is performed only by qualified personnel adhering to local electrical standards.
    Caution All wiring must be insulated for the highest voltage used.
    Caution Do not mix hazardous voltage circuits and human-accessible circuits on the same module.
    Caution Ensure that devices and circuits connected to the module are properly insulated from human contact.
    Caution (NI-9219) You must use the NI-9972 connector backshell kit to ensure that the terminals are not accessible.

    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.

    Caution 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 Zone 2.
    Caution Transient protection shall be provided that is set at a level not exceeding 140% of the peak rated voltage value of 85 V at the supply terminals to the equipment.
    Caution The system shall only be used in an area of not more than Pollution Degree 2, as defined in IEC/EN 60664-1.
    Caution The system shall be mounted in a CCC-certified enclosure with a minimum ingress protection rating of at least IP54 as defined in GB/T3836.1.
    Caution The enclosure must have a door or cover accessible only by the use of a tool.
