Classic Splice Insert Classic Splice 6" into first Rail and secure with two self-drilling screws, spacing them approximately 1" apart and tightening to 20 in-lbs. Slide second Rail over Classic Splice and secure with two more self-drilling screws. ► For Classic Splice, insert screws along the provided lines. ► Classic Splices may not be installed in the center 113rd of interior spans, or the outer 1/3 of end spans. ► Screws can be inserted on front or back of rails. BOSS • Bonded Structual Splice Insert BOSS into first Rail up until the Stop Tab. Slide second Rail fully into place. ► Rows using Classic Splice or BOSS and exceeding 100 feet of Rail must use Expansion Joints. ► Boss Splices may be installed in any location within a span. ► UFO and Bonding Hardware must be installed 1" away from the point where two Rails join together. B.PREPARE HARDWARE Slide square-headed bolts into side-facing rail slot. Space out bolts to match attachment spacing. ► Tape ends of rail, to keep bolts from sliding out while moving. ► If using T-bolts, carry hardware onto roof and proceed. C.AT TACH RAILS Drop rail with hardware into roof attachment. Level rail at desired height, then torque to 250 in-lbs. ► Rail can face either upslope or downslope on roof. ► When using attachments with longer slots, do not install Rail lower than the top of the L-Foot to avoid damage to modules.

Rail Grounding Lug Insert T-bolt in Top Rail slot and torque Hex Nut to 80 in-lbs. Install a minimum 1 O AWG solid copper or stranded grounding wire. Torque terminal screw to 20 in-lbs. ►Module Grounding Lugs can be installed anywhere along the Rail and in either orientation shown. Module Grounding Lug Insert Bolt through Manufacturer approved grounding location and torque Hex nut to 60 in-lbs. One Module Grounding Lug may be installed to one module per row. Install a minimum 10 AWG solid copper or stranded grounding wire. Torque terminal screw to 20 in-lbs. ►If using Enphase microinverters or Sunpower AC modules, Grounding Lugs may not be needed. See Page 19 for more info. ► Refer to module manufactuer for mounting location and instructions. 4.SECURE MODULES A.SECURE FIRST END Place first module in position on rails, a minimum of 1" from rail ends. Snap Stopper Sleeves onto UFO. Fasten module to rail using the UFO, ensuring that the UFO is hooked over the top of the module. Torque to 80 in-lbs. ► Ensure rails are square before placing modules. ► Hold Stopper Sleeves on end while torquing to prevent rotation. ► If using CAMO instead of UFO+ Stopper Sleeve, refer to Page 19 for CAMO installation procedure. B.SECURE NEXT MODULES Place UFO into each rail, placing them flush against first module. Slide second module against UFO. Torque to 80 in-lbs. Repeat for each following module. ► When reinstalling UFO, move modules a minimum of 1/16" so UFOs are in contact with a new section of module frame. ► When UFOs are loosened and re-tightened, ensure UFO T-bolt bottoms out in rail channel before re-torquing UFO to achieve full engagement between T-bolt and rail. ► If using Wire Clips, refer to Page 18. C.SECURE LAST END Place last module in position on rails, a minimum of 1" from rail ends. Snap Stopper Sleeves onto UFO. Secure UFO Clamps on rails, ensuring they are hooked over top of module. Torque to 80 in-lbs. ► Hold Stopper Sleeves on end while torquing to prevent rotation. ► Repeat all steps for each following row of modules, leaving a minimum 3/8" gap between rows ► If using CAMO instead of UFO+ Stopper Sleeve, refer to Page 6 for CAMO installation procedure.
