6. On the outside of the power supply, loosen the strain relief retention nut so that the wires move freely.
7. From the inside of the power supply, pull the wires through the strain relief and the hole in the end panel to remove
the old power cord.
8. If you are replacing the old strain relief with the new strain relief contained in the kit:
a. Use an adjustable wrench to unscrew the strain relief nut on the inside of the power supply to remove the old
strain relief.
b. Slide the new strain relief through the hole in the rear end panel of the power supply.
c. Secure the strain relief on the inside of the power supply using the new strain relief nut. Hand tighten the nut
and then over-tighten slightly more.
9. From the inside of the power supply, route the wires of the new power cord through the strain relief in the rear
end panel. Do not remove the tubular ferrite bead from the power switch end of the brown, black, and gray wires.
(Because the CE power cord includes the ferrite bead, you cannot route the power cord through the strain relief
from the outside of the power supply.)
10. Slide the strain relief retention nut over the wires of the new power cord and slide the retention nut forward toward
the power supply.
