Mechanical.structures should not contact the module backsheet under any expected load conditions. Additional mounting holes may not be drilled in the frame, glass or backsheet. Ensure that frame weep holes (see Appendix 8.1) are notobstructed by the mechanical installation. 5.0 ELECTRICAL INSTALLATION 5.1 PLANNINGANDDESIGN • All modules are manufactured with a sealed junction box and pre-attached cables and locking connectors. These components should not be modified or tampered with in any way. NOTE: Installers should ensure thatthe polarized locking connectors arefrom the same supplier whenconnected on the same string. We do not recommend mixing polarized interlocking connectors from different manufacturers-including connections at the inverter, combiner boxes, and modules. Ensureconnectors are clean and dry before establishing connection. Ensure thatall wire, fusing and disconnects are appropriately sized for the system design according to national, regional, and local codes. Electrical characteristics are within plus or minus5% of rated values for Isc, Voc, lmpp and Vmpp. Modules may operate, under conditions which may be significantly different than STC. MEMC suggests multiplying specified ratings by a minimum of 1.25* or more·'when speci fying the system and balance,of system components. 1.25* Refer to local codes before planning and design of the system. For detailed electrical characteristics, please refer to Section 7.0, page 10 through 11 of this Installation Manual. Determine the maximum numberof modulesconnected in series using the following formula: Ns = Vmax /Voc Where: Ns equals the maximum modules in series Vmax equals the maximum system voltage Vmax is limited lo a maximum of 1000 V for IEC and 600 V for UL Vulmell.udIS L|le 11-ludule upell ti,Luil vulldtie dl l.w|debl:culldiliulls ful l|-le bile (lefe, lu lutal tudes) WARNING: Installers should adhere to,all applicable local, regional, and national codes and regulations when designing and constructing the photovoltaic system. NOTE: In colder climates, it may be necessary to further reduce the maximum number of modules iniseries by using Voc :at the minimum expected operating temperature. 5.2 MODULEWIRING The module includes wires and polarized locking connectors from the junction box on the back of the module.The wires have sw fficientlength to connect to adjacent modules in either a pot·trail or landscape configuiation. Field replacementof connectors or cables must be avoided and it will invalidate the product warranty.

Always wire modules so that proper polarity is maintained. Avoid placing excessive tension or' the cables. There is no limit to the maximum number of series stringsthat can be combined in parallel. However, when doing so, each string must include overcurrent protection with a maximum rating of 15A. MEMC recommends the use of DC rated fuses or overcurrent protection devices with the appropriate maximum voltage rating. Do notconnect modules directlyte a parallel bus. The cross-sectional area of cable and the connector type must be selected to align with the overall system design and should include the maximum short circuit current o f the system, maximum operating temperatures, and cable run lengths. For field connections, use at a minimum #12 AWG/4 mrlf wires insulated fora minimum of 85°C. Use copper wire only. 5.3 GROUNDING The moduleframe includes several labeled=grounding holes.These holes may not be used forany other purpose. MEMC recommends a Burhdy BGBI--4 AL lay-in lug forgrbunding. .i Only Negative grounding circuits (negative polarity to ground) shall be'used within the array design. Attach the grounding lug tothe frameas follows: Step 1: Userstainless steel hardware. Step 2: Place the grounding lug over the grounding hole on the exterior of the module frame. Step 3: Place a star washer directly between the bottom of thegrounding lugand the exteriof surface of theframe. Step 4: Place an M4 or#8-32 bolt through the lug, star washerand frame grounding hole.

If the exposed surface of the course exceeds this measurement you may need to use our Classic Shake Mount instead. • Depending on the season and climate, size and location of seal tabs, and quality of the shingles, the seal tabs that adhere the shingle courses together may not effectively seal the shingles to the flashings. If this is the case, simply add several quarter-sized dabs of manufacturer accepted sealant orasphalt roofing rement; meeting ASTM D 4586 Type Il, between the flaghing ancl the chingle above. • Mounts should not be installed in areas of the roof susceptible to ice damming. Water ponding underthe shingles can reach the bolt penetration. • Take care not to damage the roofing material while working on the roof. Removing stone granules and deforming the shingles in any way can shorten the lifespan of the roofing. The value of the solar array is directly affected by the condition of the roof it is attached to. Bl 7.2.3-7 Sep-2013, Rev 6 Enuic k Mount.

Installer's Responsibilities Please review th is manual thoroughlybefore ihstalling'youy SolarMount system. This manual provides (1) supporting documentation for· building permit applications relating to Unirae's SolarMount Universal PV Module Mounting system, and (2) planning and assembly instructions for SolarMount SolarMotint products, when installed in accordance with this bulletin, will be structurally adequate and will meet the structural requirements of the IBC 2009, ASCE 7-05 and California Building Code 2010 (collectively referred to as "the Code"). Unirac also provides a limited warranty on SolarMoun[ products (page 26). SolarMount is much morethan a product. It's a system of engineered components that can be assembled into a wide variety o f PV mozinting structures. With SolarMount you'll be able to solve virtually any PV module mounting challenge. It's also a system oftechnical,support: complete installation and code compliance documentation, an on-line SolarMount Estimator. person-to-person customer service, and design a§sistance toi help you solve the toughest challenges. This iS why SolarMount is PVs most widelyused mouhting system. The installer is solely responsible for: • Complying with all applicable local or national building codes, including any that may supersede this manual; • Ensuring that Unirac and other products are appropriate for the particular installation and the installation environment; • Ensuring that the roof, its rafters, connections, and other structural support members can support the array under all code level loading conditions (this total building assembly is referred to as the building structure); • Using only Unirac parts and installer-supplied parts as specified by Unirac (substitution of parts may void the warranty and invalidate the letters of certification in all Unirac publications); • Ensuring that lag screws have adequate pullout strength and shear capacities as installed; • Verifying the strength of any alternate mounting used in lieu of the lag screws; • Maintaining the waterproof integrity of the roof, including selection of appropriate flashing; • EUSUrillg safe installation of all electrical aspeels of Llie P V array; e Ensuring correct and appropriate design parameters are used in determining the design loading used for design of the specific installation. Parameters, such as snow loading, wind speed, exposure-and topographic factor should be confirmed with the local building official or a licensed professional eigiheer. 4 4 SolarMount · Unirac Code-CompliantInstallation.Manual :ELUN[.RAC Part I. Procedure to Determine the Design Wind Load [1.1.] Using the Simplified Method - ASCE 7-05 The procedure to determine Design Wihd Load is specified by the American Sciciery of Civil Engineers and referenced in the International Building Code 2009. For purposes of this document, the values, equations and procedures used in this doctiment refer€!nce ASCE 7-05, Minimum Design Loads for Buildings and Other Structures. Please refer to ASCE 7-05 if you have any questions about' the de.Anitions or procedures presented in this manual. Unirac uses Method 1, the Simplified Method, for calculating the Design Wind Load for pressures on components and eladding in this document. The method described in this document is valid for flush, no tilt, SolarMotint Series applications on either roofs or walls. Flush is defined as panels parallel to the surface (or with no more than 3" difference between ends of assembly) with no more than 10" space between the roof surface, and the bottom ofthe PVpanels. This method is not approved for open structure ca]culations. Applications of these procedures is subjett to the following -- ASCE 7-05 limitations: 1. Thebuilding heightmust beless than 60 feet, h < 60. See note for determining h in the next section. For installations on structures greater than 60 feet, contact your local Unirac Distributor. 2. The building must be enclosed, not an open or partially enclosed structure, for example a carport. 3. The building is regular shaped with no unusual geometrical -irregil·l·.:. ily M 61-'alia] futiia, fui t:cilivle a geodesic dwitte. 4. The building is not in an extreme geographic location such as a narrow canyon or steep cliff. 5. The building has a flat orgable roof with a pitch less than 45 rlegrepq nra hip roof with.a.pitch-less-than-27-degrees. 6. If you f installation does not conform to these requirements please contact your local Unirac distributor or a local professional engineer. I;f your installation is outside the United States or does not meet all of these limitations, consult a local:professional engineer or your local building authority. Consult ASCE 7-05 for more clarificarion on the use of Method I. Lower design wind loads may be obtained by applying Method 11 from ASCE 7-05. Consult with a licensed engineer ifyoll want to use Method II procedures.

Procedure to Select Rail Span and Rail Type [2.1.] Using Standard Beam Calculations, Structural Engineering Methodology The procedi fre to determine the Unirac SolarMotint series rail type and rail span uses standard beam calculations and structural engineerbig methodology. The beam calculations nre based on, a simply supported beam conservatively·, ignoring the reductions allowed for supports of continue.us beams over multiple supports. Please refer to Part I for more inform ation on beam calculations, equations and assumptions. If beams are installed perpendicular to the eaves on a roof steeper than a 4/12 pitch in an area with a ground snow load greater [han 30psf, then additional. analysis is required for side loading on the roof attachmeht and beam, In using this document, obtaining correct results is dependent upon the following: 1. Obtain the Snow Load for your area from your local building official. 2. Obtain the Design Wind Load, pnet. See 'Part I (Procedure to Determine the Design Wind Load) for more information on calculating the Design Wind Load. 3. Please Note: The terms rail span and footing spacing are interchangeable in this document. See Figure 3 for illustrations. 4. To use Table 8 and Table 9 the Dearl Load foryourspecific installation must be;less than 5 psf, including modules and Unirac facking systems. If the Dead Load is greater than 5 psf, see your Unirae distributor, a local structural engineer or contactI Unirac. The following protedum-will guirle you in selecting a Unirac rail for a flush mount installation. It will also help determine the design loading imposed by the Uii i rae PVMounting Assembly that the building structure must be capable of supporting. Step 1: Determine the Total Design Load *5-Figure 3. Rail span andfooting spacing are;interchangeable. Woes )- The Total Design Load, P (ps,0 is determined using ASCE 7-05 2.4.1 (ASD Method equations 3,5,6 and 7) by adding the Snow Loadi, S (psID, Design Wind Load, pnel (ps.0 from Part I, Step 9 and the Dead Load (psD. Both Uplift and Down.Force Wind Loads calculated iii Step 9 of Part 1 must be investigated. Use Table 7 to calculate the Total Design Load for the load cases. Use the maximum absolute value of the three downfarce cases and the uplift case for sizing the rail. Use the uplift case only for sizing lag bolts pull out capacities (Part II, Step 6). Use the following equations or Table 7. P (psD = 1.OD + 1.081 (downforce caseill) P (ps.0 = 1.OD + 1.0pnet (downforce case 2) P (psy) = 1.00 + 0.75St + 0.75pnet (downforce case 3) P 0,0 = 0.69 + 1.Opnet (uplift) - D = Dead Load (psD S = Snow Load @sf) pnet = Design Wind Load (psD (Positive for downforce, negative for uplifO The maximum Dead Load, D (ps/9, is 5 psfbased on market research and internal data. 1 Snow Load Reducrion - The snow load can be reduced according to Chapter 7 ofASCE 7-05. The reduction is a.function of- the roof slope, Exposure Factor, Importance Factor and 77?ennal Factor. Please refer to Chapter 7 ofASCE 7-05 for more information.

Installation Manual SolarMount Step 4: Select Rail Type Selecting a span and rail type a ffects the price of yollt installation. Longer spans produce fewer wall or roof penerrations. However, longer spans create higher point load forces on the building structure. A point load force is the amount of force transferred to the building structure at each connection. It is the installer's responsibilitv to verifv that the building structure is strong enough to support the point load forces. Table 10.
