Mounting the CMU
Mount the CMU in one of three ways:

• On a wall.
• In a cabinet rack.
The CMU kit contains the CMU, CMU bracket, power connector and ground lug (Figure

To prevent the CMU from overheating, ensure that the ventilation holes on the side of the
CMU are not obstructed and that there is room for air flow across the back of the CMU
(the end opposite the connector face).
Shelf or bench top mounting
When mounting on a shelf or bench top (Figure 95), secure the CMU using its bracket. The
bracket screws to the base of the CMU.
