4.5.2 Wall-Mount Installation

The DHU may be mounted from any flat vertical surface. It is recommended that a backer

board such as 3/4-inch plywood be applied over the mounting surface to provide a secure base

for attaching the DHU. Two mounting holes are provided in the cable management tray for

securing the DHU to the mounting surface. The fasteners must be provided by the installer.

Use the following procedure to wall-mount the DHU:

Warning: Wet conditions increase the potential for receiving an electrical shock when

installing or using electrically-powered equipment. To prevent electrical shock, never install

or use electrical equipment in a wet location or during a lightning storm.

1. Obtain the appropriate fasteners (lag bolts, screw anchors, etc.) for securing the DHU to

the mounting surface.

2. Position the DHU on the mounting surface in the specified location (per the system

design) with the front panel facing up as shown in Figure 16.

Note: Provide a minimum of 3 inches (76 mm) of clearance space on both the left and right

sides of the DHU for air intake and exhaust.

(296 mm) center to center.
