Prepare the metal cover, route wires and ribbon
6. Install 2 zip ties into the holes on the metal cover. They will
later be used to secure the ribbon cable to the cover.
7. Route the large ribbon cable coming from the AMP/PSU
board along the side walls of the heatsink near the rubber
grommet. Lightly fold the ribbon cable at a 90 degree
angle over the rubber grommet. See Figure 6.2.9.
8. With the metal cover still facing up, route the fan and front
LED wires (2 conductor) around the fan and into the rub-
ber grommet as seen in Figure 6.2.8.
9. Connect the AC wiring harness to the corner of the AMP/
PSU board. Verify the connector latch is in the locked po-
sition. Gently tug on the wiring harness to verify sufficient
latching.
10. Dress the blue and brown AC wires through the rubber
grommet as shown in Figure 6.2.10.
11. Align the output connector board to the metal cover and
fasten the 2 machine screws to secure.
12. Align the metal cover to the heatsink and verify that all
ribbon cables and wires are correctly placed.
Important note: The ribbon cable and wires can easily get pinched in this step. Verify the placement of all wires before
proceeding to the next step.
13. Fasten the 3 machine screws to secure the metal cover to the heatsink as shown in Figure 6.2.5.
14. Route and lightly fold the large ribbon cable in the orientation shown in Figure 6.2.1.
15. Lightly tighten the 2 zip ties that were installed in step 6 and trim excess.
16. Connect the 3 ribbon connectors as shown in Figure 6.2.2. Verify that the fan and front LED 2-conductor wires are
connected to the appropriate locations.
