Install the output inductor
1. Place the output inductor in the power supply while guiding the long inductor wires through the opening in the
bottom of the center panel. See Figure 97 on page 242.
2. Insert the tabs on the front of the output inductor into the slots in the base of the power supply.
3. Push the electrode wire through the protective sheathing that passes through the center panel.
4. Tighten the 2 supplied mounting screws in the base of the output inductor to 69.1 kg-cm (60 inch-pounds).
5. Verify that the plastic washer is installed over the plastic hub on the rear of the quick disconnect receptacle.
6. Place the ring terminal over the silver-plated fitting and tighten the nut onto the fitting. Tighten the nut to 46.1 kg-cm
(40 inch-pounds), but do not overtighten – the plastic washer should be able to spin when the brass nut is installed.
7. Push the 90° push-to-connect fitting onto the silver-plated fitting until full seated.
