SOLARMOUNT has been classified to the system level fire portion of UL 1703. This UL 1703 classification has been incorporated into our UL 2703 product certification. SOLARMOUNT has achieved Class A, B & C system level performance for steep sloped roofs when used in conjunction with type 1, type 2, type 3 and type 10 module constructions. Class A, B & C system level fire performance is inherent in the SOLARMOUNT design,and no additional mitigation measures are required.The fire classification rating is onlyvalid on roof pitches greater than 2:12 (slopes : 2 inches per foot, or 9.5 degrees). There is no required minimum or maximum height limitation above the roof deck to maintain the Class A, B & C fire rating for SOLARMOUNT.

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 '/i" 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. A thermal 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. Option shown uses two Ilsco lugs (Model No. GBL-4DBT P/N GBL-4DBT - see product data sheet for more details) and solid copper wire.

SOLAR 000 1 MICROINVERTER SYSTEM GROUNDING S M MOUNT 1 - INSTALLATION GUIDE ; PAGE ---------------------------------------------------------- ______________________________________ SM EQUIPMENT GROUNDING THROUGH ENPHASE MICROINVERTERS The Enphase M215 and M250 microinverters have integrated grounding capabilities built in. In this case, the DC circuit is isolated from the AC circuit, and the AC equipment grounding conductor (EGC) is built into the Enphase Engage integrated grounding (IG) cabling. In order to ground the SOLARMOUNT racking system through the Enphase microinverter and Engage cable assembly, there must be a minimum of three 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 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.
