Instruction Sheet 408-8496 Wall Mount Enclosures 1278323-1 and 1278323-2 (12-Port) 09 MAY 08 Rev A Top Lug Grommet Wire Saddle (3 Places) Patch Panel Door Slide Latch Enclosure Mounting Key Hole (4 Places) Knockout for Cam Lock (Optional) Bottom Grommet Cable Clamp Bracket Figure 1 1. INTRODUCTION Wall Mount Enclosures 1278323-1 and 1278323-2 (12-port) are used for housing and distribution of fiber optic cables for indoor application. The enclosure accepts two snap-in adapter plates, and each adapter plate holds up to six duplex coupling bushings. The enclosure is designed to be wall mounted. Read these instructions thoroughly before starting installation. NOTE i Dimensions in this instruction sheet are in millimeters [with inches in brackets]. Figures are not drawn to scale. 2. DESCRIPTION The enclosure has a hinged door with a slide latch and knockout for installation of a cam lock. i Four embossed key holes provide for mounting the enclosure. Mounting screws are included with the enclosure. Also included are two `danger' labels and two 12-line `fiber patch ports' labels. 3. INSTALLATION Reasons for reissue of this instruction sheet are provided in Section 5, REVISION SUMMARY. NOTE The enclosure features removable top grommet and bottom grommet for cable exit, a cable clamp bracket to secure the cable to the enclosure, and a lug for securing the central strength member. The grommets protect the cable from damage at the opening. Fiber routing within the enclosure is facilitated by wire saddles. The integral patch panel holds the adapter plates on the outside of the enclosure. Cam Lock 559501-2 is available for use on these enclosures. Installation instructions are included with the cam lock. E 2008 Tyco Electronics Corporation, Harrisburg, PA All International Rights Reserved 3.1. Mounting and Opening the Enclosure Refer to Figure 2, and proceed as follows: 1. Determine mounting location. Allow sufficient room above and below or at the left and right sides (depending on enclosure orientation) for cable exiting the enclosure and for opening the door. 2. Slide the enclosure door latch toward the door hinge, and swing the door open. 3. Mark the wall through the top of the slots in only the top two mounting key holes. Drill the necessary holes for the screws. TOOLING ASSISTANCE CENTER 1-800-722-1111 This controlled document is subject to change.

Insert the screws through the top two mounting key holes of the enclosure and into the wall. DO NOT tighten the screws at this time. Allow the enclosure to hang. 5. Mark the wall through the holes in the bottom two mounting key holes. Remove the enclosure from the wall, drill the necessary holes for the screws, and re-hang the enclosure onto the top two screws. 6. Insert screws through the holes in the bottom two mounting key holes of the enclosure and into the wall. Tighten the screws. 7. Make sure that the top two screws are in the slots in the mounting key holes, and tighten the screws. is invisible but can damage eye tissue. NEVER eat, drink, or smoke when working with fibers. This could lead to ingestion of fiber particles. DANGER BE VERY CAREFUL to dispose of fiber ends properly. The fibers create slivers that can easily puncture the skin and cause irritation. Strip the outer sheathing and cut the central strength member of the breakout cable to the dimensions shown in Figure 4. Trim the strength members close to the end of the outer sheathing. Clean the fibers with an alcohol pad. Breakout Cable Stripping and Cutting Dimensions 2000 [79] (Approx) 8. Attach the `danger' label to the outside of the enclosure where it can readily be seen.

Position the adapter plate over the patch panel (opening in side of the enclosure) so that the split end of the lock pins align with the holes in the patch panel. See Figure 3. Trim Strength Members Close 2. Push the lock pins into the holes until the adapter plate is secure. 3. Follow same procedure for remaining adapter plate. 2 of 4 to End of Outer Sheathing Note: Not to Scale Tyco Electronics Corporation Fibers Figure 4 Rev A 408-8496 Wall Mount Enclosures 1278323-1 and 1278323-2 3.4. Routing and Terminating the Fiber Central Strength Member Secured to Lug Use the following guidelines when installing and routing the cable in the enclosure. Whatever method is used, make sure that it not only meets the application needs, but also conforms to local codes and standards: (See Detail) S Allow enough fiber in the enclosure for routing S Keep fiber in groups of 6 or 12 S Coil excess fiber around wire saddles S Keep bend radii of fiber as large as possible (always follow manufacturer's minimum bend radius) CAUTION DO NOT exceed minimum bend radii for the cable or fiber. ALWAYS avoid placing fiber under ! Cable Secured tension or torsion. to Cable Clamp Bracket The following instructions reflect a typical installation where cable is routed through only one end of the enclosure; however, cable can be routed through both ends of the enclosure. Follow the same procedure for the other end. 1. Insert the fibers through the grommet (top or bottom). Make sure that 63.5 to 76 [2.5 to 3] of the cable is inside the enclosure. Detail Setscrew Central Strength Mounting Screw 2. Lay the cable over the cable clamp bracket, and secure the cable to the cable clamp bracket using cable ties. See Figure 5. 3. Loosen the mounting screw in the lug, and pivot the lug so that the opening faces the cable. Tighten the mounting screw. Loosen the setscrew, and insert the central strength member into the lug so that the central strength member butts against the terminal. Tighten the setscrew firmly. See Figure 5. 4. Dress the fiber through the wire saddles, and terminate the fibers to connectors according to the instructions supplied with the connectors. See Figure 6. Terminal Member Lug Facing Cable Figure 5 Fiber Patch Port Label Attached Fiber Dressed Through to Inside of Door Fiber Saddles 5. Join the connectors to the coupling bushings starting at either end of the adapter plate. Make sure that each connection is secure. See Figure 6. 6. Record the connector positions using the `fiber patch port' label. Attach the label to the inside of the enclosure door. See Figure 6. 3.5. Closing and Inspection 1. Inspect installation according to the following: -- center strength member is fully inserted into lug and lug screw is tight -- there are no sharp bends or kinks in the fibers Rev A Tyco Electronics Corporation Connector Joined to Coupling Bushing Figure 6 3 of 4 408-8496 Wall Mount Enclosures 1278323-1 and 1278323-2 -- there are no fibers under tension -- all connectors are fully joined to coupling bushings 2. Close the enclosure door, and inspect closing according to the following: -- door is fully latched -- no fibers are pinched in door 5. REVISION SUMMARY S Updated document to corporate requirements 4.
