1. PLACE ATTACHMENTS The general installation method for attachments is to locate a rafter, drill a pilot hole and install the attachment. For composition roof attachments installation instructions refer to page 10. For tile roof attachments refer to page 12. For low slope roof attachments refer to page 15. When using approved third party attachments, refer to manufacturer's install instructions.
3. SECURE LUGS Grounding Lugs Rail Grounding Lug Only one Grounding Lug (Rail or Module) required per continuous subarray, regardless of subarray size (Unless frameless modules are used, see Page 20). Terminal Screw (20 in-lbs) ➢ Grounding Lugs are intended to for use with one solid or stranded copper wire, conductor size 10-4 AWG. ➢ If using Enphase microinverters or Sunpower AC modules, Grounding Lugs may not be needed. See Page 19 for more info.
CAMO A. SLIDE INTO RAIL Slide CAMO into rail channel far enough to clear the module frame. CAMO requires 6" of clearance from end of rail. A 6" Cle ara B. PLACE MODULE Place module on rails (module cells not shown for clarity). When installing CAMO the module can overhang the rail no more than 1/4". B nc e C. PULL TOWARDS END Pull CAMO towards rail ends, at 45 degree angle, so the bonding bolt contacts the module flange edge. C D.
EXPANSION JOINTS Expansion Joints are required every 100' of continuous rail to allow for thermal expansion and contraction of the system. ➢ Do not install modules over expansion joints, either Classic Splice or BOSS. 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. Assemble and secure Grounding Strap 3/8" from rail end. Slide second rail over Classic Splice leaving 1" gap between rails.

COMPOSITION SHINGLE FLASHFOOT2 Locate roof rafters and mark locations on roof. Drill 1/4" pilot holes perpendicular to the roof and back fill with roofing manufacturers' approved sealant. Slide flashing between 1st and 2nd course of shingles, ensuring both that the flashing reaches under the 3rd shingle course and doesn't overhang the downhill shingle course. Line up with pilot hole and insert supplied lag bolt with washer through flashing. With a 7/16" Socket fully seat lag bolt.
COMPOSITION SHINGLE QMPV L-MOUNT Locate roof rafters and mark locations on roof. Drill 1/4”(Lag) or 1/8"(ST) pilot holes perpendicular to the roof and back fill with roofing manufacturers' approved sealant. Slide flashing between 1st and 2nd course of shingles, ensuring both that the flashing reaches under the 3rd shingle course and doesn't overhang the downhill shingle course. Place L-foot on flute and rotate into desired position. Prepare lag bolt or structural screw with sealing washer.
TILE KNOCKOUT TILE Remove tile and mark rafter. Use base as guide to drill 1/4” pilot hole and fill with roofing manufacturer’s approved sealant. Insert lag bolt with bonded washer through base and drive until fully seated. Insert Tile Replacement Flashing, lower onto base and apply pressure over the threaded post until it dimples the flashing. Place L-Foot over dimple and tap with hammer to punch threaded post through the flashing. Ensure punched pieces of flashing are cleared away.
TILE ALL TILE HOOK Remove tile and mark rafter. Position base over rafter, adjust arm if necessary and torque hardware to 132 in-lbs (11 ft-lbs). Use base as guide to drill 1/4" pilot holes, back fill with roofing manufacturer’s approved sealant, then insert lag bolts and tighten until fully seated. Replace tiles and notch as necessary to ensure proper fit. Attach rails to either side of slot using Bonding Hardware and torque to 250 in-lbs (21-ft-lbs).
TILE QMPV QBASE UNIVERSAL TILE MOUNT Remove tile and mark rafter. Measure up 6 5/8" from bottom of tiles and mark horizontally. Align QBase over rafter center and drill two 7/32" pilot holes, back fill with roofing manufacturers' approved sealant. Place grade-8 Cap Screw under QBase, lag QBase into rafter location. Install Sub-flashing, waterproof at underlayment level according to roofing manufacturers' instructions and the Tile Roofing Industry Alliance guidelines.
LOW SLOPE ROOFS FLAT ROOF ATTACHMENT Flat Roof Attachment can be used with an L-foot for flush mounting modules on low sloped roofs. Mark locations for Flat Roof Attachment. Screws should be installed symmetrically to each other. If using a membrane flashing, remove the silicone washer's protective liner prior to attaching the membrane. Attach L-foot with washers and 3/8” hardware torqued to 250 in-lbs (21 ft-lbs). Seal attachment and/or membrane per roofing manufacturer’s requirements.
CONDUIT End CapsPENETRATION (Optional) FLASHINGS QMPV CONDUIT PENETRATION FLASHING - COMP SHINGLE Mark a drill point so that the flashing reaches up to the 3rd shingle course. Drill your conduit hole next to the rafter so you can secure the conduit below the roof surface. Cut shingle and remove nails as needed to center the drilled hole and flashing hole. Apply roofing manufacturer's approved sealant on the underside of the flashing in a Upside down U and to top of flashing.
CONDUIT MOUNT QMPV CONDUIT MOUNT - COMPOSITION SHINGLE Place conduit mounts along path of conduit. Lift shingle above mount location and insert flashing into position. Mark center for drilling, remove flashing and drill pilot hole with 1/8" bit. Clean area, fill hole with roofing manufacturer's approved sealant. Lift shingle and slide Conduit Mount into place. Prepare the lag bolt with sealing washer and pipe clamp (not included).
END CAPS End Caps add a completed look and keep debris and pests from collecting inside rail. Firmly press End Cap onto rail end. ➢ End Caps come in sets of left and right. Check that the proper amount of each has been provided. WIRE CLIPS Wire Clips offer a simple wire management solution. Press Clip into Slot Snap Clip Closed Firmly press Wire Clip into top rail slot. Run electrical wire through open clip. Snap closed once all wires have been placed.
MICROINVERTER KITS Use IronRidge's Microinverter Kit to bond compatible microinverters and power optimizers to the racking system. Insert Microinverter Kit T-bolt into top rail slot. Place compatible microinverter or power optimizer into position and tighten hex nut to 80 in-lbs.
SYSTEMS USING MICROSTORAGE PRODUCTS PHAZR Use IronRidge's Microinverter Kit to bond compatible microstroage devices to the racking system. Insert Microinverter Kit T-bolt into top rail slot. Place compatible microstorage into position and tighten hex nut to 80 in-lbs. COMPATIBLE PRODUCTS Microinverter Kit (80 in-lbs) PHAZR PHAZR Devices PHAZR-X, where X is 6-12.
