For safety reasons, module pre-wiring should not be <br />performed on:the rooT. <br />Leave covers off.J-boxes. They will be installed When the <br />modules are installed on the rails. <br />jU <br />4%./109\ <br />I I <br />· · DZ" 79=-·--«e·/ 'f u:·- .··: tN=M- 143529@44 <br />// 1.1 <br />ZZ- 1-boxes <br />Installing the First Module: In high-profile installations, the <br />best practice would be to install a safety bolt (Mi"-20 x 1/2")and <br />flange nut (both installer provided) fastened to the module bolt <br />slot at the aligned (lower) end of each rail. It will prevent the <br />lower end clamps and clamping bolts from sliding out of the rail <br />slot during installation. <br />Figure 17 <br />*-1.*91.-3.-11 -1.-2361 i i 11·ile>framei'·'- <br />1/2" minimum '1 3¥,1.1.11:k..
