9 – Power Supply Component Replacement
Install the power cord and strain relief
1. Are you installing a new strain relief?
 If yes, install the strain relief as shown in Figure 64. Do not tighten the strain relief retention nut.
 If no, loosen the strain relief retention nut on the strain relief.
Figure 64
2. Tighten the strain relief nut inside the power supply to secure the strain relief to the power supply.
3. CSA models: From the outside of the power supply, slide the power cord through the strain relief.
CE models: Push the power cord through the strain relief from inside the rear panel. (You cannot route the power
cord through the strain relief from outside the power supply because of the ferrite core installed on the power wires.)
CCC models do not ship with a power cord. To install a power cord on a CCC system, slide the power cord through
the strain relief from the outside of the power supply; or, to maintain CE certification, install power cord kit 228886.
4. Route the 3 power wires up the chase inside the rear panel to the top of the power switch.
5. Insert the 3 wires in the top of the power switch as shown in Figure 65 and Table 13 on page 195. Tighten the 3 set
screws to 23 kg-cm (20 inch-pounds).
6. Tighten the strain relief retention nut.
