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.

board. At the same time realign the rear panel with the power supply. See Reattach the rear panel on page 106.
