Signal Connection
Note Refer to the Safety Information section before removing equipment covers or
connecting or disconnecting any signal wires.
When connecting your signals to the SCXI-1328, follow the labeling on the
SCXI-1328 for the appropriate module, as indicated in Figure 2.
To connect the signal to the terminal block, perform the following steps,
referring to Figures 1 and 2 as necessary:
1. Unscrew the top cover screws and remove the cover.
2. Loosen the strain-relief screws and remove the strain-relief bar.
3. Run the signal wires through the strain-relief opening. You can add
insulation or padding if necessary.
4. Prepare your signal wire by stripping the insulation no more than
12 mm.
5. Connect the wires to the screw terminals by wrapping the wires around
the screw. No bare wire should extend past the screw head. Exposed
wire reduces the safety isolation between the high voltage and safe low
voltages.
6. Tighten the screws to a torque of 5–7 in.-lb.
7. Connect safety earth ground to the safety-ground solder lug. Refer to
the
Safety Information section for connection information.
8. Reinstall the strain-relief bar and tighten the strain-relief screws.
9. Reinstall the top cover and tighten the top cover screws.
10. Connect the terminal block to the module front connector as explained
in the Installation section.
