Mount the rear panel assembly on the back of the KPA500 as shown in Figure 39. It may be easier to set the
KPA500 on a side panel so you can adjust the fit on the top and bottom at the same time and get it to clear the
Z-bracket assembly on the bottom. Secure the assembly with six screws as shown.

Look through the top of the KPA500 and check the clearance of gray wire leading to the center pin of the
RF output connector and the Z-bracket. If necessary, bend the wire at the pin as needed for clearance as shown
in Figure 40. A flat blade screwdriver is an excellent tool to bend the wire.

Check the fan to ensure the RF OUTPUT or RF INPUT cables do not interfere with free motion of the
blades. Adjust the cable positions as needed.
