2. Route the new power cord wires through the strain relief in the rear panel from inside the power supply. (The CE
power cord includes a ferrite core. Therefore, you can not route the power cord through the strain relief from the
outside of the power supply.)
3. Slide the strain relief retention nut over the wires of the new power cord and slide the nut forward toward the power
supply.
4. Route the brown, black, and grey wires to the top of the power switch.
5. Insert the wire connectors into the top of the power switch and use a #1 Phillips screwdriver to tighten the set
screws to 10 in-lbs (11.5 kg cm). Refer to the figure on the previous page for the correct color assignments. “L1”,
“L2”, and “L3” are marked on the power switch above each set screw.
6. Secure the green/yellow ground wire to the heatsink using the Phillips screw and tighten to 20 in-lbs (23.0 kg cm)
with the star washer between the ring terminal and the heat sink.
7. Position the wires in the wire chase up the side of the end panel and out of the way of the power board. Once the
wires are in place, tighten the strain relief retention nut onto the strain relief to secure the new power cord.
Install a plug on the power cord (CSA and CE)
Use a plug that meets national and local electrical codes. The plug must be connected to the power cord by a licensed
electrician.
