:FUNIRAC Unirac Code-Compliant Installation Manual SolarMount <br />[3.2.5] Installing the modules <br />Pre-wiring Modules: if modules are the Plug and Play type, <br />no pre-wiring is required, and you can proceed directly to <br />"Installing the First Module" below. <br />If modules have standard J-boxes, each module should be <br />pre-Wired with one end of the intermodule cable For ease of <br />installation. For safety reasons, module pre-wiring should not be <br />perfotmed on I:lie roof. <br />Leave covers off.J-boxes. They will be installed when the <br />modules are installed on the nails. <br />/ 8 .4 <br />,/7\ <br />''f \34 1 w '4' 1 <br />...+I., r.. / .... 9 16 * •. •36*..,a.. :...d. 40¥1 <br />i it·-'EL Ap*=E«··.=-y- '"-, ·-4. „4.·thn,95.-=Al.- 2 -*+ <br />1.1 <br />ZZ J.boxes <br />Installing the First Module: In hjgh-profile installations, the <br />best practice would be to install a safety bolt (W'-20 x M")and <br />flange nut (both installer provided) fastened to the module bolt <br />slot at the aligned (lower) end ofeach rail. It will prevent the <br />lower end clamps and clamping bolts from sliding out ofthe rail <br />slot during installation. <br />Figure 17 <br />1/2" minimurn <br />L <br />d.ilt- <br />If there is a return cable to the inverter, connect it to the first 111 lili- 1 11 <br />-- 5 11 I lil lil l- 1 I '1module.

Connect intermodule <br />cable to the second module and close the J-box cover. Turn the <br />second module face up (Fig. 17). With T-bolts, mid-clamps and <br />flange nuts, secure the adjacent sides o f the first and secoiid <br />modules. Align the second module and securely tighten the <br />flange nuls (Fig. 19). <br />Figure 18 <br />r-• 37?9·.1 kidaoia,716'47 <br />1.%ret#.1.2.6.4.; 333 1 <br />1233%7-;-riabiuies·oii-15:'-RE€Ind.. lah,de>Out. <br />5€41 <br />For a neat installation, fasten wire management devices to rails <br />with self-drilling screws.-#-'-,1,1&,/ I -t'=.:; i ,"-'..
