ADCP-96-058 • Issue 1 • July 2005 Admonishments Important safety admonishments are used throughout this manual to warn of possible hazards to persons or equipment. An admonishment identifies a possible hazard and then explains what may happen if the hazard is not avoided. The admonishments — in the form of Dangers, Warnings, and Cautions — must be followed at all times. These warnings are flagged by use of the triangular alert icon (seen below), and are listed in descending order of severity of injury or damage and likelihood of occurrence. Danger: Danger is used to indicate the presence of a hazard that will cause severe personal injury, death, or substantial property damage if the hazard is not avoided. Warning: Warning is used to indicate the presence of a hazard that can cause severe personal injury, death, or substantial property damage if the hazard is not avoided. Caution: Caution is used to indicate the presence of a hazard that will or can cause minor personal injury or property damage if the hazard is not avoided. General Safety Precautions Danger: 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. Danger: Do not look into the ends of any optical fiber. Exposure to laser radiation may result. Do not assume the laser power is turned-off or that the fiber is disconnected at the other end. Warning: Before digging, check with all local utilities for the presence of buried cables or pipes. Contact with underground cables or pipes, especially electric power cables and gas service lines, could interrupt local utility service and cause serious personal injury and extensive property damage.

ADCP-96-058 • Issue 1 • July 2005 1 DESCRIPTION This section provides a description of the hand-hole enclosure plus the product specifications. 1.1 Hand-Hole Enclosure The hand-hole enclosure, shown in Figure 1, is an Outside Plant (OSP), molded-plastic, belowground mounting system for the MST. It may also be used with other products that are similar in function and design to the MST. Access to the interior of the enclosure is through a rectangular 30.5 x 7.25 inch opening located on top of the enclosure. The opening is fitted with a hinged cover that locks in a vertical upright position when opened. The MST mounts on the underside of the cover and the cable slack is stored in the compartment below. Opening the cover swings the MST up and out of the enclosure for above-ground access to the optical ports. Cable rings (optional) within the enclosure provide cable management for distribution and drop cable slack. The hand-hole enclosure is open at the bottom and must be mounted on compacted fill material for support. Cutouts in the bottom edge of the enclosure allow the enclosure to be placed over 2.5-inch (outside diameter) distribution cable conduit. Tie points are provided for securing the distribution cable conduit to the enclosure. Entry/exit points for drop cables are marked on the ends of the enclosure. A hole must be drilled into the enclosure at each selected drop cable entry/exit point. A drop cable conduit clamp kit (accessory) is available for securing drop cable conduit to the enclosure at the selected entry/exit point. MST MOUNTED ON HAND-HOLE COVER DROP CABLE DROP CABLE CONDUIT (OPTIONAL) 20603-A DISTRIBUTION CABLE CONDUIT (OPTIONAL) Figure 1. Multi-Fiber Services Terminal Hand-Hole Enclosure Page 4 © 2005, ADC Telecommunications, Inc. ADCP-96-058 • Issue 1 • July 2005 When installed, the top of the hand-hole enclosure will be flush with the top of the ground. An electronic marker disc (option) may mounted on the underside of the cover. This allows the enclosure to be detected with a frequency marker locator if the enclosure becomes covered by backfill. The locator transmits a signal to the marker and the marker reflects the signal back to the locator. The rugged construction of the enclosure and ribbed side-walls allow it to withstand the weight loads imposed by pedestrian and yard equipment traffic without danger of collapse. A grounding bar (option) is also available for MST’s that require grounding connections. 1.2 Specifications The specifications for the hand-hole enclosure are provided in Table 1. Table 1.

If armored distribution cable will be installed, a grounding system must also be installed. MST Installation – After the hand-hole enclosure is installed, the MST distribution cable must be uncoiled and routed through the distribution cable conduit to a separate splice enclosure (not provided). Some slack must be stored within the enclosure and the MST must be secured to the enclosure cover. MST Distribution Cable Splicing – The MST distribution cable must be spliced to the system OSP cable at a separate splice enclosure. Use locally approved practices and procedures for splicing. Refer to the Multi-Fiber Services Terminal User Manual (ADCP-96-040) for the MST optical port and fiber designations. Drop Cable Installation and Connection – The drop cables must be routed into the enclosure and some slack stored. Service is enabled by connecting the drop cable connectors to the subscriber distribution ports on the MST. Site Restoration - The enclosure cover must be closed and secured, the area around the enclosure must be backfilled, and the landscaping restored. 2.2 Unpacking and Inspection This section provides instructions for opening the shipping boxes, verifying that all parts have been received, and verifying that no shipping damage has occurred. Use the following procedure to unpack and inspect the cabinet and all accessories: 1. Open the shipping carton(s) and carefully unpack the hand-hole enclosure from the protective packing material. 2. Check the hand-hole enclosure for broken or missing parts. If there are damages or parts are missing, contact ADC (see Section 7) for an RMA (Return Material Authorization) and to reorder if replacement is required.

The location must be accessible and must not expose the worker to possible safety hazards. In addition, the enclosure should not be located in a place where it is likely to be damaged. The enclosure should be installed directly in line with the trench that was used for the distribution cable conduit. The enclosure may be used with the MST-2, MST-4, MST-6, MST-8 or MST-12 which are equipped respectively with 2-, 4-, 6-, 8-, or 12-fiber distribution cables. Warning: Before digging, check with all local utilities for the presence of buried cables or pipes. Contact with underground cables or pipes, especially electric power cables and gas service lines, could interrupt local utility service and cause serious personal injury and extensive property damage. 3.2 Cable Management Bracket Installation (Option) Install the four cable management brackets (if included with the enclosure) as shown in Figure 3. The cable management brackets are used for storing distribution and drop cable slack. 20648-B Figure 3. Installing Cable Management Brackets Page 9 © 2005, ADC Telecommunications, Inc. ADCP-96-058 • Issue 1 • July 2005 3.3 Excavation The excavation must be deep enough to provide a fill base that will maintain stability for the enclosure and the MST mounted within it. There must be room for 6 inches (15.25 cm) of compacted aggregate fill below the enclosure. Excavate a rectangular hole for the enclosure as shown in Figure 4. Fill the bottom of the hole with stone aggregate, tamping it as it is filled to build a 6 inch (15.25 cm) layer with a level surface. The stone aggregate will provide a stable base to support the enclosure. Note: Use crushed rock 3/8-inch or less in size mixed with stone dust (per local practice) to create the base. The name of the material may differ in different geographical areas. Possible names are Class 5, stone dust, aughts (0s) and ones (1s), or stone aggregate FINAL GRADE LEVEL 18 IN.

ADCP-96-058 • Issue 1 • July 2005 20483-A Figure 5. Adjusting Enclosure the Height 3.5 Grounding System Installation A grounding system is required if the MST is equipped with armored distribution cable. MST’s that require grounding are equipped with a grounding stud. The metallic elements of the armored cable are connected to the internal side of the MST grounding stud. Install a grounding system (not provided) that meets all local electrical code requirements. Follow local codes for grounding system installation, use of clamps, wire size, and any other grounding requirements. Typically, #6 AWG copper wire is used for the grounding wire. Install the grounding system inside the enclosure where it will not interfere with the conduit or cables. Leave sufficient slack in the grounding wire to allow it to be attached to the MST grounding stud and to allow for flexing when the enclosure cover is opened and closed. A copper grounding bar that attaches to the enclosure cover is available as an option. The grounding bar may be used to complete the connection between the grounding system and the MST grounding stud. If a grounding bar is included, secure it to the hand-hold cover as shown in Figure 6 using the screws provided. Connect the grounding wire (from the grounding system) to one of the lugs on the grounding bar. Following installation of the MST, use a short length of #6 AWG copper wire to connect the grounding stud on the MST to one of the lugs on the grounding bar.
