Connecting to a Spring-Terminal Connector
What to Use
■ NI-9213 spring-terminal connector
■ 0.08 mm2 to 1.0 mm2 (28 AWG to 18 AWG) copper conductor wire with 7 mm
(0.28 in.) 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-9213
What to Do
Complete the following steps to connect wires to the spring-terminal connector.
123
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
NI-9940 backshell kit to protect connections to the NI-9213.

Minimizing Thermal Gradients
Changes in the ambient air temperature near the front connector or a thermocouple
wire conducting heat directly to terminal junctions can cause thermal gradients.
Observe the following guidelines to minimize thermal gradients and improve the
system accuracy.
■Use small-gauge thermocouple wire. Smaller wire transfers less heat to or
from the terminal junction.
■Run thermocouple wiring together near the spring-terminal connector to
keep the wires at the same temperature.
■Avoid running thermocouple wires near hot or cold objects.
■Minimize adjacent heat sources and air flow across the terminals.
■Keep the ambient temperature as stable as possible.
■Make sure the NI-9213 terminals are facing forward or upward.
■Keep the NI-9213 in a stable and consistent orientation.
■Allow the thermal gradients to settle aer a change in system power or in
ambient temperature. A change in system power can happen when the
system powers on, the system comes out of sleep mode, or you insert/remove
modules.
■Use the NI 9940 backshell kit.
■If you connect any extension wires to thermocouple wires, use wires made
of the same conductive material as the thermocouple wires.
Overvoltage Protection
The NI-9213 provides overvoltage protection between any two inputs.
Note Refer to the device datasheet on ni.com/manuals for more
information about overvoltage protection.
