power resistor.
Install the shrink tubing over the resistor and part of the
solder lug.
Attach the solder lug to the cabinet using a 6-32 screw
and nut. Use one of the available holes near the PS10.
Insert the free end of the wire in the center terminal of
the three position terminal block of the PS10 output. This
is the neutral DC output.

Install the LED into the front panel. First insert the black
grommet through the hole in the front panel from the
outside. Then insert the LED into the grommet from the
inside. The grommet snaps around the base of the LED
and holds it in place.
Check that all the pieces of heat shrink tubing are properly
positioned over the connections they are supposed to
protect and shrink with a heat gun.
Now the
AC power wiring
will be hooked up to the power
supply.
Attached line cord
Separate the power cord wires back to about 1/4" from
the strain relief and cut one of the wires about 2" from the
strain relief. Slip 1/2" of heat shrink tubing over the short
wire and solder it to the center connector of the fuse
holder. Cut 1/2" of heat shrink tubing and slip it over the
remaining power cord wire. Solder the wire to the center
connector of the power switch.
Cut an 8" piece of red high voltage (thick insulation)
hookup wire, strip 1/4" at each end and solder to the
bottom
terminal of the power switch. Use 1/2" of heat
shrink tubing over this connection as well.
Secure the free end of the wire in the leftmost terminal of
the 4-position terminal block (AC input) on the PS10
power supply board.
Cut a 2" piece of brown high voltage hookup wire and
secure the free end of the wire in the rightmost terminal of
the 4-position terminal block (AC input) on the PS10
power supply board.
Use jumpers on the 4-position terminal block of the PS10
power supply to select line voltage, as shown in Figure 6.
