NI SCXI-1378 Installation Instructions
❑
Wire cutter
❑
Wire insulation stripper
❑
Matrix expansion cable (to expand the columns of a matrix)
❑
Matrix expansion plug (to expand the rows of a matrix)
Tip
NI recommends using 28 AWG wire (ribbon or discrete) for use with the SCXI-1378
terminal block.
3. Connect Signals
To connect signals to the terminal block, refer to Figures 1 and 2 while
completing the following steps:
1.
Prepare the signal wire by stripping the insulation no more than 7 mm.
2.
Remove the top cover screw.
3.
Unsnap and remove the top cover.
4.
Loosen the two strain-relief screws on the strain-relief assembly.
5.
Run the signal wires through the strain-relief opening.
6.
Insert the stripped end of the wire fully into the terminal. Secure the
wire by tightening the screw of the terminal. No bare wire should
extend past the spring terminal. Exposed wire increases the risk of
a short-circuit causing a failure.
Note
When connecting wires to the SCXI-1378, refer to Tables 1 and 2 to determine
terminal mapping for the chosen topology.
7.
Tighten the two screws on the strain-relief assembly to secure the
cables.
8.
Reinstall the top cover.
9.
Replace the top cover screw.
