Note: Use crushed rock
2.Use appropriate lifting equipment to place the FMS into the center of the hole. Lifting loops are provided on either side of the FMS for attaching a sling or chain.
3.Use a carpenter’s level to verify that the FMS is level. If it is necessary to add or remove fill for leveling, tamp any added fill to maintain the base stability.
3.4Cable Conduit Installation
Select the conduit entrance hole(s) for the OSP feeder and distribution cables. Refer to Figure 4 for the location of the holes. If necessary, additional conduit entrance holes may be cut using a power drill and hole saw. Place and route the conduit into the entrance hole(s). If preferred, the FMS may be installed without conduit. OSP cables may be routed into the FMS at any point that is convenient. Cut the cable entrance hole to match the size of the cable.
3.5Grounding System Installation
Install a grounding system (not provided) that meets all local electrical codes. Check 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 FMS where it will not interfere with the conduit or cables. Connect the grounding wire to the grounding system. Leave sufficient slack in the grounding wire to allow it to be routed into the cabinet after the cabinet is mounted on the sleeve.
3.6Back Fill
If installing conduit, hand shovel stone aggregate under the conduit to avoid damage from the power tamper. Complete the back fill as follows:
1.Add stone aggregate evenly around the FMS and tamp. Fill to approximately 6 inches (15.2 cm) from the top of the excavation.
2.Complete the
