• Two M3-. 5 x 10 mm socket head machine
• Two #4 lock washers
• 2’ of red 14 to 18 gauge wire
• 2’ of black 14 to 18 gauge wire
Mounting the SainSmart
Start by placing the controller board on the plywood
panel as shown in Figure 6. The board should be about an
inch from the edge of the panel. The area to the right of
the controller can be used to mount additional electronics if
needed. With the controller in place, trace the four
mounting holes with a pencil.
Drill a 3/16” hole at each mark and insert a 1” #6
machine screw with washer into each hole and secure it
with a #6 hex nut (Figure 7).
Slip the board over the screws as shown in Figure 8.
You may need to loosen the nuts a little to allow the screws
to slip into the holes of the controller board. Secure the
board with a #6 lock washer and hex nut.
Set the four-position switch block to 1 = off; 2 = on; 3
= off; and 4 = on as in Figure 9. Set the
two-position switch block to 1 = off and
2 = on as shown in Figures 9 and 10.
Mounting the Power
To mount the power supply, start by setting the supply
in place on the notched panel (Figure 11). Place it about
an inch from the end and trace its outline.
Flip the supply on its side with its back on the line
closest to the end of the panel. Using a square, extend the
holes to the edge of the supply so that you can transfer the
position of the holes to the panel; refer to Figure 12.
Drill a 3/16” hole at each mark in the panel, then
secure with two M3-. 5 x 10 mm screws, #6 washers, and
#4 lock washers as in Figure 13.
For the next step, you will need the three-prong power
cord. Connect the three colored leads on the cord to the
AC input terminals on the power supply as shown in Figure
14. Connect the green wire to GND, the white wire to N,
