4. KSU Installation
The KSU is designed for wall mounting only. The KSU should NOT be mounted directly on
a masonry surface. If the KSU is to be mounted on a masonry surface, a wooden
backboard of sufficient size should be attached to the wall and the KSU mounted on the
backboard.
1. Using the mounting template as a guide, mark the 2 mounting screws locations on
the MDF backboard.
2. Pre-drill 2 screw holes and install 2 pan-head No. 10 screws into the backboard. The
screw heads should protrude about 1/4-in. from the backboard plywood surface.
3. Lift the KSU over the 2 screws allowing the screws to extend into the KSU slotted
mounting holes. As the KSU is allowed to rest in place on the mounting screws it will
slip over the screw shanks until the top of the slot is reached. Properly installed, the
KSU power transformer (where the KSU AC power cord is located) is positioned in the
upper left corner. The power switch and Power/Heartbeat LED are positioned at the
left side of the KSU toward the bottom.
It is very important that the KSU be correctly mounted to allow proper power supply heat
dissipation.
