Signal Connection. To connect the signal to the terminal block, use the following procedure:
1. Remove the grounding screw of the top cover.
2. Snap out the top cover of the shield by placing a screwdriver in the groove at the bottom of
the terminal block.
3. Slide the signal wires, one at a time, through the front panel strain relief. Additional
insulation or padding may be added if necessary.
4. Connect the wires to the screw terminals, making sure to supply a Vcc for each bank used.
No ground signal connection is required for the SCXI-1162.
5. Tighten the strain relief by tightening the larger screws.
6. Snap the top cover back in place.
7. Replace the grounding screw to ensure proper shielding.
8. Connect the terminal block to the SCXI-1162 front connector as explained in the SCXI-1326
Installation section, the next section in this chapter.
Figure 2-5 shows a parts locator diagram for the SCXI-1326 terminal block.
Warning:
If high voltages (
≥
42 Vrms) are present, the safety earth ground must be
connected to the strain relief tab. This complies with UL 1244 and fully protects
against electric shock when the terminal block is not connected to the chassis. To
connect the safety earth ground to the strain relief tab, run an earth ground wire in
the cable from the signal source to the terminal block. National Instruments is not
liable for any damages or injuries resulting from inadequate safety earth ground
connections.
