Locate the utility box and knock out two mounting holes in the back of the box. Using the box as a template, posi- tion the box in the desired mounting position and secure the box to the upright or baffle using the screws provided. Drill 3 / 16 -in. holes if necessary for mounting. 2. Attach the forked terminal end of the conduit assembly to the bottom of the utility box. Connect each of the five fork terminals to the modular jack. See Fig. 8. 3. Using the screws provided with the modular jack, attach the jack to the utility box. 4. Locate the gasket and screws provided with the cover. Carefully remove the inner portion of the gasket and attach the cover to the utility box. 5. Locate the plugs provided with the utility box. Use RTV on the threads and secure the plugs into the unused box openings. 6. Route the other end of the conduit assembly to the control box. The connector at this end of the conduit assembly must be connected to the LEN (local equipment network) connector on TB3 for 30GTN,R and 30GUN,R models and must be connected to the Main Base Board (MBB) at MBB-J4 for 30GXN,R models.
