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.
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:
Standard Series:
• the total width of the modules,
• plus 1/4” inch for each space between modules (for mid- clamp),
• plus approximately 3" ( 1½ inches for each Endclamp)
Pro Series:
• the total width of the modules,
• plus 1” inch for each space between modules (for mid- clamp),
• plus 0 to 1" ( 0 to ½ inches for each Endclamp)
RAILS MAY BE PLACED PARALLEL OR PERPENDICULAR TO RAFTERS

SYSTEM LEVEL FIRE CLASSIFICATION
CODE COMPLIANCE NOTES
C
INSTALLATION GUIDE PAGE
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. System level fire performance is inherent in the SOLARMOUNT design, and no additional mitigation measures are required. The fire classification rating is only valid on roof pitches greater than 2:12 (slopes ≥ 2 inches per foot, or 9.5 degrees). The system is to be mounted over fire resistant roof covering rated for the application. There is no required minimum or maximum height limitation above the roof deck to maintain the system fire rating for SOLARMOUNT. Module Types
& System Level Fire Ratings are listed below:

This racking system may be used to ground and/or mount a PV module complying with UL1703 only when the specific module has been evaluated for grounding and/or mounting in compliance with the included instructions.
UL2703 CERTIFICATION MARKING LABEL
Unirac SOLARMOUNT is listed to UL 2703. Certification marking is embossed on all mid clamps as shown.
Labels with additional information will be provided . After the racking system is fully assembled, a single label should be applied to the SOLARMOUNT rail at the edge of the array. Before applying the label, the corners of the label that do not pertain to the system being installed must be removed so that only the installed system type is showing.
Note: The sticker label should be placed such that it is visible, but not outward facing.

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.
Quick Tip: Pre-drill the pilot hole through the flat flashing lag bolt location for easier installation.
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.
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.
For high snow load conditions, install the L-foot as shown above, and install the rail on the downslope face of the L-Foot
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 lag bolts are screwed into the rafter.
• Insert the flashing under the shingle above and over the shaft of the standoff.
(No-Calk™ 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.
SIDE MOUNT SOLARHOOK :
• Remove or slide up the roof tile, position the roof hook above the roof rafter
• Place SolarHook 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 tile hook to the rafters using included lag screws.
• Slide down or re-insert the tile.

SPLICE & THERMAL BREAK
E
INSTALLATION GUIDE PAGE
SPLICE INSTALLATION (IF REQUIRED PER SYSTEM DESIGN)
If your installation uses SOLARMOUNT splice 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 can 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. To install, slide T-feature on splice into the T-slot on each rail, centering the splice between the two rails. Tighten each bolt until the bolt-head is flush against the splice and torqued to 10 ft-lbs. Installation is complete when the bonding hardware penetrates the opposite side of the rail and the assembly torque is achieved. 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 1/2" - 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. Determine location of expansion joints prior to installation of L-feet and rails. To create a thermal expansion joint, set gap between rails that is sufficient for proper instal lation of end clamps and tooling to achieve required torque. 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 en gineer. Runs of rail less than 40 feet in length, with more than two pairs spliced together, are an acceptable installation for the SOLARMOUNT systems.
Rails in expansion joint configurations are considered cantilevered and must follow the cantilever rule, on both sides of the expansion joint, which states that the maximum amount of rail that can be cantilevered is 1/3 the respective adjacent span. An expansion joint must not be spanned by a PV module. Installing a module over an expansion joint would defeat the goal of a thermal break and could result in damage to the array.
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. Optional grounding may be achieved through Enphase MI. See PG. I.

ALIGN RAILS: Align one pair of rail ends to the edge of the installation area. The opposite pair of rail ends will overhang installation area. Do not
Trim them off until the installation is complete. If the rails are perpendicular to the rafters, either end of the rails can be aligned, but the first module must be installed at the aligned end.
If the rails are parallel to the rafters, the aligned end of the rails must face the lower edge of the roof. Securely tighten all hardware after alignment is complete.
Mount modules to the rails as soon as possible. Large temperature changes may bow the rails within a few hours if module placement is delayed.

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.
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.

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.
TEMPORARY BONDING CONNECTION DURING ARRAY MAINTENANCE
When removing modules for replacement or system maintenance, any module left in place that is secured with a bonding Midclamp will be properly grounded. If a module adjacent to the end module of a row is removed or if any other maintenance condition leaves a module without a bonding mid clamp, a temporary bonding connection must be installed as shown
• Attach Ilsco SGB4 to wall of rail
• Attach Ilsco SGB4 to module frame
• Install solid copper wire jumper to Ilsco lugs
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. See product data sheets for correct torque values.
PERIODIC INSPECTION: Conduct periodic inspections for loose components, loose fasteners or any corrosion, immediately replace any affected components.

ELECTRICAL CONSIDERATIONS
SOLARMOUNT is intended to be used with PV modules that have a system voltage less than or equal to 1000 VDC. 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 responsibility to check local codes, which may vary. See below for interconnection information.
Ilsc o SGB-4
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.
SOLID
COPPER WIRE
TEMPORARY BONDING CONNECTION DURING ARRAY MAINTENANCE
When removing modules for replacement or system maintenance, any module left in place that is secured with a bonding Midclamp will be properly grounded. If a module adjacent to the end module of a row is removed or if any other maintenance condition leaves a module without a bonding mid clamp, a temporary bonding connection must be installed as shown
• Attach Ilsco SGB4 to wall of rail
• Attach Ilsco SGB4 to module frame
• Install solid copper wire jumper to Ilsco lugs
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. See product data sheets for correct torque values.

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. The following lists the specific modules that were tested and the applicability of those certifications to other modules that might come onto the market.
In addition to UL 2703 certification, Unirac performs internal testing beyond the requirements of certification tests in order to establish system functional limits, allowable loads, and factors of safety. These tests include functional system tests, and destructive load testing.
Mechanical Load Test Modules
The modules selected for UL 2703 mechanical load testing were selected to represent the broadest range possible for modules on the market. The tests performed cover the following basic module parameters:
• Frame thicknesses greater than or equal to 1.0 mm
• Basic single and double wall frame profiles (some
complex frame profiles could require further analysis to
determine applicability)
• Clear and dark anodized aluminum frames
• UL2703 Certification Load Ratings: o Down– 113.4 PSF , Up – 50.4 PSF , Down-Slope – 14.7 PSF
• Tested Loads: o Down – 170.10 PSF , Up – 75.60 PSF, Down-Slope – 22.05 PSF
• Maximum Area of Module = 21.06 sqft

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. Class A system level fire performance is inherent in the SOLARMOUNT design, and no additional mitigation measures are required. The fire classification rating is only valid 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 system fire rating for SOLARMOUNT. Module Types & System Level Fire Ratings are listed below:
