6 – Power Supply Component Replacement
CE power cords
1. Are you installing a new strain relief?
 If yes, insert the strain relief into the rear panel and tighten the retention nut onto the strain relief. Loosely tighten
the strain relief nut on the outside of the power supply onto the strain relief.
 If no, continue with the next step.
2. Route the wires for the power cord through the strain relief from the inside of the rear panel.
 Because the power cord includes the ferrite core, you cannot route the power cord
through the strain relief from the outside of the power supply. Do not remove the ferrite
core from the power cord wires.
3. Press the connector for the brown wire onto the pin on the upper left side of the power switch.
4. Press the connector for the blue wire onto the pin on the upper right side of the power switch.
5. Tighten the green/yellow ground wire to the heatsink. Tighten to screw to 23.0 kg∙cm (20 inch-pounds).
6. Position the brown and blue wires in the wire chase up the side of the rear panel and out of the way of the power
board. At the same time realign the rear panel with the power supply. See Reattach the rear panel on page 106.
7. Tighten the strain relief nut on the outside of the rear panel.
8. Complete the following procedures:
a. See Install the component barrier on page 101.
b. See Install the power supply cover on page 99.
