expansion board in the wall mount enclosure. See
Figure 3 below and Figure 4 on page 4 for locations of
option kit components.
1. Disconnect indicator from power source.
2. Open enclosure.
3. Screw eight 1/2" standoffs (PN 71452) into the
holes in the enclosure backplate.
4. Clip the six cable ties that secure the cable

board. Remove CPU board power supply cable
and replace with the cable in the expansion
board option kit. Connect new cable to power
input connector on CPU board.

CPU board. Slide the ribbon cable into the
cable clamps and extend cable to full length.

expansion board. See Figure 4 on page 4).
7. Mount two-card expansion board on installed
standoffs. (Ensure that ribbon cable is routed
under the expansion board and extends to the
right of the board.) Use four 1/4" screws (PN
14822) to secure board to standoffs.
8. Install four 1/2" standoffs (PN 71452) onto the
expansion board to support option cards.
