The KSU is a plastic frame cabinet designed for wall mounting. Employing the KSU mounting template provided with the 
KSU, mark the location of the two screws to mount the KSU. Again, the KSU must not be mounted on a masonry or dry-
wall surface, in this case a wooden backboard is required, refer to paragraph [Back Board Installation]. The distance 
between mounting holes is shown in Figure 3.3.2. 
The KSU is mounted with two #10 or larger, 1.5 inch or longer screws. First, drill pilot holes in the two locations marked, 
insert the screws and tighten leaving about 0.5 inch exposed. Hang up the KSU on the screws and tighten the KSU.
