2.4 DRU Mounting Procedure

The DRU may be mounted on any flat vertical or horizontal surface. A slot is provided in each of the four mounting feet for inserting a fastener. The fasteners must be provided by the installer. Use the following procedure to mount the DRU:

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.

Note: To insure that all optical connectors and transceivers remain dust-fr ee 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 the DRU to the mounting surface.

2. Position the DRU on the mounting surface in the specified location (per the system design). Make sure the LED will be visible when the unit is mounted.

Note: To ensure there is adequate air circulation for cooling, provide a minimum of 3 inches (76 mm) of clearance space on all sides of the DRU (except the bottom). In addition, at least one surface of the DRU installation area must be open to the building’s interior air space. If a portable/flexible antenna will be installed, allow a minimum of 9 inches (229 mm) clearance along the surface with the antenna.

ADCP-75-112 • Issue 2A • June 2001

Note: In mounting situations where fiber, power, and coaxial cable pass-through holes are planned, it is critical that these holes be placed far enough away from their respective connectors to avoid forming overly tight bend radii. Tight bend radii can damage fiber optic 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) diameter Fiber optic cable (twin lead): 0.12 inch (3.0 mm) diameter Antenna coaxial cable: 0.16 inch (4.0 mm) diameter If planned cable diameters are greater than those listed, please consult with the cable

manufacturer 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 be required for fiber, power, or coaxial cables. Observe any additional instructions that may be printed on the template such as the recommended fasteners and clearance requirements.

4. Drill appropriately sized holes in the mounting surface for the mounting screws or wall anchors 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.

3. Dress and secure the power cable at the DRU per standard industry practice.

4. When the installation of the DRU is completed, refer to Section 4 of the Digivance ICS Installation and Operation Manual (ADCP-75-110) for the system turn-up and test procedures.

2.8.2 Power Provided by AC/DC Converter

When the DRU is powered by an AC/DC converter, it must be powered by a UL Listed stand alone Limited Power Supply (LPS) unit with a rated output of 48 Vdc at 1.2 Amps. Use the following procedure to connect the DC and AC power cables when the DRU is powered by an AC/DC converter.

1. Locate the DC power cable that is attached to the AC/DC converter as shown in Figure 17.

2. Connect the DC power cable to the 48 Vdc connector on the DRU (see Figure 16).

3. Locate the AC power cord which is provided with the AC/DC power converter. Use only the AC power cord provided with the power converter or an equivalent UL/CUL listed and certifie d 3-conductor, 18 AWG cord terminated in a molded-on plug cap rated 125 V, 15 A with a maximum length of 6 feet (1.8 m).

Note: The AC/DC converter is intended to be used with a 3-wire grounding type plug which has a grounding pin. Equipment grounding is to ensure safe operation. Do not defeat the grounding means. Verify converter is reliably grounded when installed.

4. Connect the receptacle end of the power cord to the AC connector on the AC/DC converter (see Figure 17).

5. Route the plug end of the power cord to the specified AC outlet (per the system design) and connect plug to outlet.

Warning: Be sure to check the nameplate rating of the AC/DC converter to avoid overloading

circuits which may cause damage to over-current protection devices and supply wiring.

6. Verify that the STATUS LED on the DRU turns red or blinking red. This indicates that the DRU is powered but not receiving a forward path optical signal.

Note: Early versions of the DRU use a steady red LED to indicate all major fault conditions including no optical signal received. Later versions of the DRU use a blinking red LED to indicate no optical signal received.

7. Dress and secure both power cables per standard industry practice.

8. When the installation of the DRU is completed, refer to Section 4 of the Digivance ICS Installation and Operation Manual (ADCP-75-110) for the system turn-up and test procedures.
