■ copper conductor wire with of insulation stripped from the end
■Flathead screwdriver with a 2.3 mm x 1.0 mm (0.09 in. x 0.04 in.) blade,
included with the NI-9220
What to Do
Complete the following steps to connect wires to the spring-terminal connector.
1. Insert the screwdriver into a spring clamp activation slot to open the
corresponding connector terminal.
2. Press a wire into the open connector terminal.
3. Remove the screwdriver from the activation slot to clamp the wire into place.
High-Vibration Application Connections
If your application is subject to high vibration, NI recommends that you use the
backshell kit to protect connections to the NI-9220 with spring terminal.
