with the screw holes in the metal plate on
the bottom of the new magnetics assembly.

base using the 6 screws. Tighten the

into the bottom of the power supply until the
assembly snaps into place.
5. On the fan side of the power supply, attach
the ring terminal for the output inductor’s
white wire to the stud labeled “WHT” using
an 8 mm (5/16 inch) nut driver. Tighten the
nut to 23.0 kg·cm (20 inch·pounds). See
Figure 87 on page 176.

Also put back in place any other wires
you removed from the “WHT” stud.

page 176, attach the ground wire to the
metal base plate of the magnetics assembly.
