O <br /> Rail Grounding Lug <br /> Insert T-bolt in Top Rail slot and torque Hex Nut to 80 in-lbs. Install <br /> a minimum 10 AWG solid copper or stranded grounding wire.Torque <br /> terminal screw to 20 in-lbs. ( ex Nu <br /> 80 in-lbs) <br /> Module Grounding Lugs can be installed anywhere along the Rail m <br /> and in either orientation shown. <br /> Module Grounding Lug j <br /> Insert Bolt through Manufacturer approved grounding location and torque Use with one solid or stranded copper <br /> Hex nut to 60 in-lbs.One Module Grounding Lug may be installed to Module Grounding Lug wire,conductor size 10-4AWG. <br /> one module per row. Install a minimum 10 AWG solid copper or stranded <br /> grounding wire.Torque terminal screw to 20 in-lbs. <br /> BOLT <br /> Terminal Screw <br /> If using Enphase microinverters or Sunpower AC modules, (20 in-lbs) STAR WASHER <br /> Grounding Lugs may not be needed.See P.a..ge._.1...9 for more info. -- <br /> GROUNDING LUG <br /> Refer to module manufactuer for mounting location and Hex HeaddFLANGE NUT <br /> instructions. (60 in-lbs) <br /> A. SECURE FIRST END <br /> Place first module in position on rails, a minimum of 1" <br /> from rail ends. Snap Stopper Sleeves onto UFO. Fasten UFO <br /> module to rail using the UFO, ensuring that the UFO is Stoppe (80 in-lbs) <br /> hooked over the top of the module. Torque to 80 in-lbs. 1"From F—Sleeve <br /> r <br /> Rail End <br /> D Ensure rails are square before placing modules. <br /> D Hold Stopper Sleeves on end while torquing to prevent rotation. <br /> D If using CAMO instead of UFO+Stopper Sleeve,refer to Page 19 <br /> for CAMO installation procedure. <br /> UFO can be installed on modules 30 to 46mm. <br /> B. SECURE NEXT MODULES B <br /> Place UFO into each rail, placing them flush against first <br /> module. Slide second module against UFO. Torque to 80 <br /> in-lbs. Repeat for each following module. 7UFO <br /> (80 in-lbs) <br /> When reinstalling UFO,move modules a minimum of 1/16" so <br /> UFOs are in contact with a new section of module frame. <br /> When UFOs are loosened and re-tightened,ensure UFO T-bolt <br /> bottoms out in rail channel before re-torquing UFO to achieve full <br /> engagement between T-bolt and rail. <br /> If using Wire Clips,refer to Page 18. <br /> RC1 <br /> C. SECURE LAST END <br /> Place last module in position on rails, a minimum of 1" <br /> from rail ends. Snap Stopper Sleeves onto UFO. Secure UFO <br /> UFO Clamps on rails, ensuring they are hooked over top (80 in-lbs) <br /> of module. Torque to 80 in-lbs. <br /> D Hold Stopper Sleeves on end while torquing to prevent rotation. <br /> D Repeat all steps for each following row of modules,leaving a <br /> minimum 3/8"gap between rows <br /> lo If using CAMO instead of UFO+Stopper Sleeve,refer to Page 6 <br /> o r - • . •M-1.
