Connecting the Chassis Ground
Locate the #6 toothed lug. It’s packed in the “Screw Nut Lug” envelope. Locate the green
ground harness. It has green wire with 3 FASTONs.
1. Cut the long green wire to 8” length as shown in Figure 16.
2. Remove 3/8” of insulation from the now 8” wire. Twist and tin the strands. Loop
and crimp the wire on the lug as shown in Figure 16. Solder the wire to the lug.
3. Connect the blue 0.25” wide FASTON to the center terminal of the IEC power
connector.
4. Connect the blue 0.187” wide FASTON to the center terminal of the unswitched
outlet.
5. Connect the red 0.187” wide FASTON to the center terminal of the switched
outlet.
6. Dress the long green wire toward the ground stud behind the switch as shown in
Figure 17. Use two more cable ties in the tie down positions shown to secure the
ground wire.

7. Use a plain 6-32 nut to hold the ground lug on the chassis stud.
Connect the Toroidal Transformer to the power supply
Locate the following items associated with the toroidal transformer:
1. Toroidal Transformer
2. rubber mounting pads (qty 2)
3. #8-32 nut and split ring lock-washer
For now, we’ll work only with the toroidal transformer itself. Save the mounting pads,
lock-washer and nut for the later step when the power supply is mounted to the chassis
for testing.
