4 Certification Details SnapNrack Series 200 system has been evaluated by Underwriters Laboratories (UL) and Listed to UL /ANSI Standard 2703 for Grounding/Bonding and echanical Loading. Grounding/Bonding The Series 200 system has been designed in compliance with UL Standard 2703 Section 9.1 Exception, which permits accessible components that are not part of the fault current ground path to not be electrically bonded to the mounting system. The UL Listing covers bonding for a load rating up to 45 psf. For more details on the integrated grounding functionality see the Grounding Specifications section. This racking system may be used to ground and/or mount a PV module complying with UL 1703 only when the specific module has been evaluated for grounding and/or mounting in compliance with the included instructions. See the Grounding Specifications for the list of modules tested with the Series 200 system for integrated grounding. Ground Lug has been evaluated to both UL 467 and UL 2703 Listing reuirements. Series 200 has been listed with the following Enphase microinverter models for grounding/bonding: 215, 250 and C250. The Enphase microinverters are certified to be mounted to SnapNrack rail with the LPE Attachment or to the module frame with the Enphase Frame ount. When installing the Enphase microinverters per the specifications in the LPE Installation section of this manual, the total roof-mounted PV system is bonded (modules, racking and microinverters) and grounded through the Enphase ground circuit when the Enphase units are properly grounded through to the service entrance. Therefore, no ground lugs or euipment grounding conductor (EGC) are reuired on the SnapNrack systems. Series 200 has been Listed with the following SolarEdge optimizer models for grounding/bonding: P300-5NC4ARS and P320-5NC4ARS. The SolarEdge optimizers are certified to be mounted to SnapNrack rail with the LPE Attachment or to the module frame with the SolarEdge Power Optimizer Frame-ounted odule Add-On. When installing the SolarEdge optimizers per the specifications in the LPE Installation section of this manual, the total roof-mounted PV system is bonded to the optimizer backing plate (modules, racking and optimizers) and grounded through the ground lugs installed on the SnapNrack rail. Therefore, it is not necessary to run an EGC to each SolarEdge optimizer. Note: Frame-ounted odule Add-On has been evaluated for all modules except Suniva modules. The mounting system Bonding Listing is only valid when installed with a Non-Separately Derived PV system. The PV system is reuired to have a direct electrical connection to another source, such as connecting to the grid via a grid interactive inverter. echanical Loading The Series 200 system is Listed for mechanical loading for different load ratings depending on the mounting configuration and PV module installed. For more details on the mechanical loading details see the echanical Loading Specifications section. SnapNrack engineered systems should only be used with SnapNrack components and hardware. Any application outside of those specified in this Installation anual and the Structural Engineering Report may void the warranty and structural certification could become invalid. If the module clamps have been engaged and need to be loosened and reengaged, SnapNrack recommends moving the module frame 3mm to engage the bonding pin in a new location if reuired by the AHJ. The UL Listing covers mechanical load ratings for the various module orientations and positive, negative, and side load ratings. These values can be found in the echanical Loading Specifications section. SnapNrack recommends a periodic re-inspection of the completed installation for loose components, loose fasteners, and any corrosion, such that if found, the affected components are to be immediately replaced. 1

8 Pre-Installation Reuirements System Layout 1) Typically most ground mounted arrays are installed in a landscape configuration, with the long side of the PV modules horizontal and the rails running up the slope. This is different from roof mount installations which typically are in a portrait configuration with the long side of the module running up slope and the rails running horizontally. 2) Layout rails so that module frame ends do not overhang mounting rails by more than 25% of total module frame length. Verify that mounting rail spans are in accordance with the Configuration Table in your state s Engineering Letter. Also, verify that rail ends do not overhang by a distance greater than 30% of the acceptable rail span specified in the same table. 3) Submit array plans to local permitting jurisdiction and proceed with the layout only when all permits for the project have been granted by the authority having jurisdiction. Layout Note: odule mid clamps are installed between modules in a row and reuire 0.5 inch of space between the modules. X clamps reuire 1.5 inches of extra rail to extend past the end of the module frame. When installing multiple rows of modules, a minimum spacing gap of 1/8 inch should be used between columns. Layout rails such that module frame ends do not overhang mounting rails by more than 25% of total module length. Note: All Engineering Letters for each state are available for download at 5
