Note that SOLARMOUNT rails make excellent straight edges for used for attachment through existing roofing material, such as asphalt shingles, doing layouts. sheathing or sheet metal to the building structure. Center the installation area over the structural members as much as possible Leave enough room to safely move around the array during installation. Some building codes and fire codes require minimum clearances around such installations, and the installer should check local building code requirements for compliance. The length of the installation area is equal to: • the total width of the modules, • plus 1/a" inch for each space between modules (for mid- clamp), • plus approximately 3 inches (11/z inches for each Endclamp) RAILS MAY BE PLACED PARALLEL OR PERPENDICULAR TO RAFTERS q i-Pe'k-(RiJgej - -- -Y Ll-- J_ 7M_ HIGH PROFILE Z LOW PROFILE W _.

DRILL PILOT HOLES: Center the roof attachment over the rafter and drill a pilot hole(s) for the lag bolt(s). NOTE: Determine lag bolt size and embedment depth. Quick Tip: Pre -drill the pilot hole through the flat flashing lag bolt location for easier installation. FLAT FLASHING INSTALLATION: Insert the Flat Flashing so the top part is under the next row of shingles and the hole lines up with the pilot hole. INSTALL LAG BOLTS & L -FOOT: Insert the lag bolt through the L -Foot in the order shown in the illustration. Verify proper orientation before tightening lag bolts. See Unirac Flat Flashing Manual for Additional Details. 2 PIECE ALUMINUM STANDOFF WITH FLASHING & L -FOOT: • If necessary cut an opening in the roofing material over a rafter to accommodate the flashing riser. • Install the standoff, ensuring that both tag bolts are screwed into the rafter. • Insert the flashing under the shingle above and over the shaft of the standoff. (No -Calk T" collar does not require sealing of the flashing and standoff shaft) • Add L -Foot to top with bolt that secures the EPDM washer to the top of the standoff. See Standoffs & Flashings Installation Manual 907.2 for Additional Details. TOP MOUNT TILE HOOK & L -FOOT: • Remove or slide up the roof tile, position the roof hook above the roof rafter • Place Tile Hook in the middle of the underlying interlocking tile's valley. Drill 3/16 inch pilot holes through the underlayment into the center of the rafters. Securely fasten each the hook to the rafters with two 5/16" x 31h" lag screws. Slide down or re-insert the tile. • Attach L Foot to tile roof hook. See Tile Hook Universal Mount Installation Manual for Additional Information. 000 M0o SOLAR SPLICE & THERMAL BREAK � MOUNT INSTALLATION GUIDE ;PAGE -------------------------------------------------------------------------------------------------------------------------------------- SPLICE INSTALLATION (IF REQUIRED PER SYSTEM DESIGN) If your installation uses SOLARMOUNTsplice bars,attach the rails together before mounting to the L -feet /footings. Use splice bars only with flush installations or those that use low-profile'tilt legs. A rail should always be supported by more than one footing on both sides of the splice. There should be a gap between rails, up to 3/16" at the splice connections. T -bolts should not be placed less than a distance of 1" from the end of the rail regardless of a splice. TORQUE VALUE (See Note on PG. A) Hex head socket size 5/16"- Do not exceed 10 ft -lbs. Do not use Anti -Seize. Max length of spliced rail is 40 ft. An expansion joint is required > 40 ft. EXPANSION JOINT USED AS THERMAL BREAK Expansion joints prevent buckling of rails due to thermal expansion. Splice bars may be used for thermal expansion joints. To create a thermal expansion joint, slide the splice bar into the footing slots of both rail lengths. Leave approxi- mately 1/2" between the rail segments. Secure the splice bar with two screws on one side only. Footings (such as L -feet or standoffs) should be secured normally on both sides of the splice. No PV module or mounting hardware component should straddle the expansion joint. Modules must clearly end before the joint with mounting hardware (top mount Endclamps) terminating on that rail.T-bolts should not be placed less than a distance of 1" from the end of the rail regard- less of a splice. The next set of modules would then start after the splice with mounting hardware beginning on the next rail.Athermal break is required every 40 feet of continuously connected rail. For additional concerns on thermal breaks in your specific project, please consult a licensed structural engineer. Runs of rail less than 40 feet in length, with more than two pairs spliced together, are an acceptable installation for the SOLARMOUNT systems. Bonding connection for splice used as a thermal break.

For standard system grounding a minimum 10AWG, 105°C copper grounding conductor should be used to ground. a 1000 VDC system, according to the National Electric Code (NEC). It is the installer's responsibilityto check local codes,which may vary. See below for interconnection information. INTERCONNECTION INFORMATION There is no size limit on how many SOLARMOUNT & PV modules can be mechanically interconnected for any given configuration, provided that the installation meets the requirements of applicable building and fire codes. GROUNDING NOTES The installation must be conducted in accordance with the National Electric Code (NEC) and the authority, having jurisdiction. Please refer to these resources in your location for required grounding lug quantities specific to your project. The grounding / bonding components may overhang parts of the array so care must be made when walking around the array to avoid damage. Conductor fastener torque values depend on conductor size.

SM EQUIPMENT GROUNDING THROUGH &PHASE' MICROINVERTERS rr.,,�,""`�`�,�~�,£ `• The Enphase M215 and M250 microinverters have integrated. grounding . , S '�• capabilities built in. In this case, the DC circuit is isolated from tKi AC circuit, and the AC equipment grounding conductor (EGC) is built into the Enphase Engage integrated grounding (IG) cabling. - ,n. ,ate - K .+.• �, �. In ,order to ground the SOLARM_ OUNT racking system through the Enphase microinverter and Engage cable assembly, there must be a minimum of three ' 5'4!,-_: PV modules connected to the' same trunk cable within.a continuous row. ' Continuous row is defined as a grouping of modules installed and bonded. per the requirements of this -installation guide sharing the same two rails. The s_ c microinverters are bonded to the SOLARMOUNT rail via the mounting hardware. Complete equipment grounding is achieved through the Enphase Engage cabling with integrated grounding (IG). No additional EGC grounding cables are required, as all fault current is carried to ground through the Engage cable.
