4. Position the RIU in the designated mounting space in the rack (per system design) and
then secure the mounting brackets to the rack using the four machine screws provided
(use #12-24 screws or M6 x 10 screws, whichever is appropriate) as shown in Figure 5.
Note: Provide a minimum of 3 inches (76 mm) of clearance space on both the left and right
sides of the RIU for air intake and exhaust.
2.3.2 Wall-Mount Installation
The RIU 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 RIU. Two mounting holes are provided in the cable management tray for securing
the RIU to the mounting surface. In addition, the mounting brackets may be removed and then
reinstalled in such a way that they can be used for securing the RIU to the mounting surface.
Either method for mounting may be used at the discretion of the installer. The fasteners must be
provided by the installer. Use the following procedure to wall-mount the RIU:
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 RIU to
the mounting surface.
2. If the mounting brackets will be used to secure the RIU to the mounting surface, proceed
to step 3. If the mounting brackets will not be used to secure the RIU to the mounting
surface, skip steps 3 and 4 and proceed to step 5.
