SM SYSTEM LAYOUT SOLAR MOUNT B INSTALLATION GUIDE PAGE PLANNING YOUR SOLARMOUNT INSTALLATIONS The installation can be laid out with rails parallel to the rafters or perpendicular to the rafters. Note that SOLARMOUNT rails make excellent straight edges for doing layouts.
SM SOLAR MOUNT CODE COMPLIANCE NOTES C INSTALLATION GUIDE PAGE SYSTEM LEVEL FIRE CLASSIFICATION The system fire class rating requires installation in the manner specified in the SOLARMOUNT Installation Guide. 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 system level performance for steep sloped roofs.
SM SOLAR MOUNT ROOF ATTACHMENT & L-FEET D INSTALLATION GUIDE PAGE ROOF PREPARATION: Layout and install flashing at rafter locations determined per Design and Engineering Guide. 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. FLASHING INSTALLATION: Insert the flashing so the top part is under the next row of shingles and the hole lines up with the pilot hole.

Use splice bars only with flush installations or those that use low-profile tilt legs. A rail can be supported by more than one footing on both sides of the splice.
SM ATTACH RAIL TO L-FEET SOLAR MOUNT INSTALLATION GUIDE PAGE 3/8” T-bolt PLACE T-BOLT INTO RAIL & SECURE BOLT: Insert 3/8” T-bolt into rail at L-foot locations. Apply Anti-Seize to bolt. Rotate T-bolt into position. SECURE T-BOLT: Apply Anti-Seize to bolt. Rotate T-bolt into position. ALIGN POSITION INDICATOR: Hand tighten nut until rail alignment is complete. Verify that position indicator on bolt is vertical (perpendicular to rail) TORQUE VALUE (See Note on PG.
SM MICROINVERTER MOUNTING SOLAR MOUNT INSTALLATION GUIDE PAGE INSTALL MICROINVERTER MOUNT T-BOLT: Apply Anti-Seize and install pre-assembled ¼” dia. bonding T-bolts into top ¼” rail slot at microinverter locations. Rotate bolts into position. G INSTALL MICROINVERTER: Install microinverter on to rail. Engage with bolt. INSTALL MICROINVERTER: TORQUE VALUE (See Note on PG.
SM SOLAR MOUNT MICROINVERTER SYSTEM GROUNDING H 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.

SM ENDCLAMP, FIRST MODULE &TRIM SOLAR MOUNT INSTALLATION GUIDE PAGE INSTALL MODULE END CLAMPS: The End clamp is supplied as an assembly with a 1/2" hex head bolt that is accessible at the ends of rails. The clamp should be installed on the rails prior to installing end modules. INSTALL END CLAMPS ON RAIL: Slide end clamp on to rail by engaging the two t-guide brackets with the top slot of the rails. Ensure bolt is extended as far as possible so that clamp is positioned at max.
INSTALL MIDCLAMPS: Midclamp is supplied as an assembly with a T-bolt for module installation. Clamp assemblies may be positioned in rail near point of use prior to module placement. INSERT MIDCLAMP ASSEMBLY: Insert 1/4" T-Bolt into top slot of rail PLACE ADJACENT MODULE AGAINST CLAMPS: Modules must be tight against clamps with no gaps. Tighten nut to required torque. POSITION INDICATOR - SERRATED T-BOLT: Verify the T-bolt position indicator is perpendicular to the rail.
SM REMAINING MODULES SOLAR MOUNT INSTALLATION GUIDE PAGE INSTALL REMAINING MID-CLAMPS: Proceed with module installation. Engage each module with previously positioned Midclamp assemblies. POSITION T-BOLT ALIGNMENT MARKS: Verify that the position indicator(s) & T-bolt shaft(s) are angled in the correct position. Tighten to final torque. TORQUE VALUE (See table and notes on PG. A) 11 ft-lbs. No anti-seize.

SM APPENDIX A SOLAR MOUNT Q System Certification PAGE The SOLARMOUNT system has been certified and listed to the UL 2703 standard (Rack Mounting Systems and Clamping Devices for Flat-Plate Photovoltaic Modules and Panels). This standard included electrical grounding, electrical bonding, mechanical load and fire resistance testing. In conducting these tests, specific modules are selected for their physical properties so that the certifications can be broadly applied.
