Install the magnetics
1. Align the screw holes in the plastic base with the screw holes in the metal plate on the bottom of the new magnetics
assembly.
2. Attach the new magnetics to the plastic base using the 6 screws. (See Figure 13.)
3. Align the wires from the magnetics with the notches in the center panel so that the wires do not get pinched.
4. Press the plastic base and the magnetics into the bottom of the power supply until the assembly snaps into place.
5. On the power board side of the unit, connect the wires at J13, J14, J15, J18, J19, J20, J21, and J22. (See Figure 9
on page 8.) Tighten each one to 23.0 kg-cm (20 inch-pounds).
6. On the fan side of the power supply, attach the ring connector for the output inductor's white wire to the stud labeled
"WHT" using a 8 mm (5/16 inch) nut driver. See Figure 11 on page 9.

If you removed any other wires from the WHT stud, reinstall them.
7. Reconnect the air filter/regulator's drain hose to the hole in the bottom of the base.
8. Using the screw you removed in step 2 on page 8, attach the ground wire to the metal base plate of the magnetics
assembly with a torque setting of 17.3 kg-cm (15 inch-pounds). See Figure 10 on page 8.
9. On the power board side of the power supply, connect the wires for the transformers and inductors on the new
magnetics assembly to the power board at J13, J14, J15, J18, J19, J20, J21, and J22. Tighten each screw to
23.0 kg-cm (20 inch-pounds). See Figure 9 on page 8.
Reattach the panels
1. Push the front and rear panels into the base of the power supply to re-engage the snaps.
2. Tighten the retaining screws with a torque setting of 8.1 kg-cm (7 pound-inch). (See Figure 4 on page 5.)
3. Reconnect the control board's ribbon cable to the power board.
4. Reconnect the ground wire to the ground wire clip.
5. Tighten the strain relief nut on the torch lead, work lead, and power cord.
Reinstall the component barrier and power supply cover
1. Position the barrier so that the folded section will cover the top of the power board. The edge with the long cutout
and the 2 notches should align with the front panel; the edge with the 3 notches should align with the rear panel.
2. Put the front-panel edge of the barrier in place first, then the rear-panel edge. The notches on each side of the barrier
should align with the ribs on the inside of the front and rear panels. As you slide the barrier into place, make sure the
bottom edge is between the wires and the track on the base.

The barrier will not fit in the same track with the power supply cover.
