:PUNIRAC Unirac Code-Compliant InstaUation Manual SolarMount [3.2.5] Installing the modules Pre-wiring Modules: If modules are the Plug and Play type, no pre-wiring is required, and you can proceed directly to "Installing the First Module" below.-+0--** If modules have standard J-boxes, each module should be .' installation. For safety reasons, module pre-wiring should not be f % 14pre-wired with one end of the intermodule cable for ease of 1 IP,/2, performed on the roof. ,Leave covers off J-boxes. They will be installed when the '-17 modules are installed on the rails.Lf J-boxes Installing the First Module: In high-profile installations, the best practice would be to install a safety bolt (¥4"-20 X V2")and flange nut (both installer provided) fastened to the module bolt slot at the aligned 0ower) end of each rail. It will prevent the lower end clamps and clamping bolts from sliding out of the rail slot during installation. Figure 17 1/2" minimum 4 - Module frame If there is a return cable to the inverter, connect it to the first module. Close the J-box cover. Secure the first module with -r T-bolts and end clamps at the aligned end of each rail. Allow . half an inch between the rail ends and the end clamps (Fig.18). .......... Finger tighten flange nuts, center and align the module as needed, and securely tighten the flange nuts (10 ft lbs).End clamp 232"- 1/4" module bolt and flange nut L Rail Installing the Other Modules: Lay the second module face down (glass to glass) on the first module. Connect intermodule cable to the second module and close the J-box cover. Turn the second module face up (Fig. 17). With T-bolts, mid-clamps and flange nuts, secure the adjacent sides of the first and second modules. Align the second module and securely tighten the flange nuts (Fig. 19). For a neat installation, fasten wire management devices to rails with self-drilling screws. Repeat the procedure until all modules are installed. Attach the outside edge of the last module to the rail with end clamps. Trim offany excess rail, being careful not to cut into the roof.
