ADCP-75-112 • Issue 2A • June 2001Page 9© 2001, ADC Telecommunications, Inc.2.4 DRU Mounting ProcedureThe DRU may be mounted on any flat vertical or horizontal surface. Aslot is provided in eachof the four mounting feet for inserting afastener. The fasteners must be provided by theinstaller. Use the following procedure to mount the DRU:Warning:Wet conditions increase the potential for receiving an electrical shock wheninstalling or using electrically-powered equipment. To prevent electrical shock, never installor use electrical equipment in a wet location or during a lightning storm.Note: To insure that all optical connectors and transceivers remain dust-free during installation,leave all dust caps and dust protectors in place until directed to remove them for connection.1. Obtain the appropriate fasteners (lag bolts, screws, wall anchors, etc.) for securing theDRU to the mounting surface.2. Position the DRU on the mounting surface in the specified location (per the systemdesign). Make sure the LED will be visible when the unit is mounted.Note:To ensure there is adequate air circulation for cooling, provide aminimum of 3inches (76 mm) of clearance space on all sides of the DRU (except the bottom). Inaddition, at least one surface of the DRU installation area must be open to the building’sinterior air space. If aportable/flexible antenna will be installed, allow aminimum of 9inches (229 mm) clearance along the surface with the antenna.Note:In mounting situations where fiber, power, and coaxial cable pass-through holesare planned, it is critical that these holes be placed far enough away from their respectiveconnectors to avoid forming overly tight bend radii. Tight bend radii can damage fiberoptic cable and reduce RF signal levels. The DRU mounting template (part # 1154319)provides the clearances for the following cable types:Power cable (cat 3 and 5): 0.2 inch (5.2 mm) diameterFiber optic cable (twin lead): 0.12 inch (3.0 mm) diameterAntenna coaxial cable: 0.16 inch (4.0 mm) diameterIf planned cable diameters are greater than those listed, please consult with the cablemanufacturer to determine the cable’s recommended minimum bend radii.3. Mark the location of the mounting holes and of any pass-through holes that may berequired for fiber, power, or coaxial cables. Observe any additional instructions that maybe printed on the template such as the recommended fasteners and clearancerequirements.4. Drill appropriately sized holes in the mounting surface for the mounting screws or wallanchors and for the fiber, power, or coaxial cables (if pass-through holes are required).5. Place the DRU in position for mounting and then install the fasteners as shown in Figure 7.6. Securely tighten each fastener.
