Align the edges of the modules and snug them together (Fig.21,page22). Trim the rails to the total width of the modules to be mounted. Place a rail adjacent to the outer mounting holes. Orient the footing bolt slot outward. Place a clip slot adjacent to the mounting holes,following the arrangement you selected earlier. Assemble the clips,mounting bolts,and flange nuts. Torque the flange nuts to 5 foot-pounds. Wire the modules as needed. For safety reasons,module wiring should not be performed on a roof. For a neat installation,fasten cable clamps to rails with self-tapping screws. [3.3.4] Installing the module-rail assembly Bring the module-rail assembly to the installation site. Keep rail slots free of debris that might cause bolts to bind in the C liP slots. Consider the weight of a fully assembled panel.

This may enhance perfor- mance in hotter climates. Adjust the position of the panel as needed to fit the installa- tion area. Slide the remaining L-feet bolts onto the other rail, attach L-feet,and finger tighten with flange nuts. Align L-feet with mounting holes previously drilled into the roof. Install lag bolts into remaining L-feet as described in"Laying out and installing L-feet"above. Torque all footing flange nuts to 20 foot-pounds. Verify that all lag bolts are securely fastened.
