Complete the following steps.
1.
Using a 3.5 mm (9/64 in.) diameter drill bit, drill two holes through the silkscreened
crosshairs on the label side of the cover. When drilling, place the cover on a flat surface,
such as a drill press, and drill slowly to minimize burrs.
2.
Replace the cover on the base, lining up the drill holes with the holes in the enclosure.
3.
Screw the M3 × 6 (#4-40 × 5/16") screws in with a torque of 0.90 N · M to 1.13 N · M
(8 in. · lb to 10 in. · lb). Screwing within the recommended torque range avoids stripping
the threads of the enclosure holes.
Removing the SCB-100A PCB from the Base
Complete the following steps to remove the SCB-100A from the base.
1.
Disconnect the cable from the SCB-100A, if connected, and remove the top cover.
2.
Loosen the strain-relief screws, shown in Figure 1, with a #2 Phillips screwdriver.
3.
Remove any signal wires from screw terminals with a flathead screwdriver.
4.
Remove the printed circuit board mount screws and chassis ground lug, shown in
Figure 2, with a #1 Phillips screwdriver.
5.
Remove the connector screws, shown in the following figure, with a flathead screwdriver.
6.
Tilt the PCB up and pull it out of the enclosure base.

Note
The threaded holes on the SCB-100A for the PCB mounting should not be
used more than five times. Unscrewing and reinstalling the PCB will produce a
compromised connection.
Specifications
The following specifications are typical at 25 °C, unless otherwise noted.
Caution
Do not connect hazardous voltages (>30 V RMS/42 V peak/60 V DC) to
the SCB-100A.
