2.3 Mounting Procedure

The RIU may be either rack-mounted or wall-mounted. Of the procedures that follow, use
whichever procedure is appropriate for the installation.
2.3.1 Rack-Mount Installation
The RIU may be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. Both
US standard and metric machine screws are included for rack mounting the RIU. When
loading the RIU in a rack, make sure the mechanical loading of the rack is even to avoid a
hazardous condition such as a severely unbalanced rack. The rack should safely support the
combined weight of all the equipment it holds. In addition, the maximum recommended
ambient temperature for the RIU is 50º C (122º F). Allow sufficient air circulation or space
between units when the RIU is installed in a multi-unit rack assembly because the operating
ambient temperature of the rack environment might be greater than room ambient.
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.
Use the following procedure to install the RIU in the equipment rack:
1. The RIU is shipped with the mounting brackets installed for 19-inch rack installations. If
mounting the RIU in a 19-inch rack, proceed to step 4. If mounting the RIU in a 23-inch
rack, proceed to step 2.
2. Remove both mounting brackets from the RIU (requires TORX screwdriver with T20 bit).
3. Reinstall both mounting brackets so the long side of the bracket is flush with the RIU
front panel as shown in Figure 4. Use the screws removed in step 2 to re-attach the
brackets to the RIU enclosure.
