Company: SUNRUN SOUTH UC, OBA SNAPNAAC Type of Equipment PV Module Mounting Systems (QIMS) Model Designation: Ultra Rall Mounting Systems (UR-40 and UR-60) UL File Number: £359313 To whom it may concern: This letter Is confirmation that the Ultra Rail mounting systems we,-e Investigated In accordance with the Standard for Radc Mounting Systems, Mountlng Devices, Clamping/Retention Devices and Ground LUgs ror Use with Flat-Plate Photo110ltaic Modules and Panels, UL /ANSI 2703, 1" Edition, dated January 28, 2015. These systems have been evaluated for bonding. mechanical loading and nre per the requirements of UL 2703. The systems have been evaluated for the creatio n of an equipotentia l bond for the intercomected pho tovoltaic module frames. which can then be gr ounded in accordance to !he U.S. Nalional Electrical Cod� (U.S. NEQ. The systems employs top-down damps which have been evaluated for frame-to-system bonding. at a mounting torque and with specific modules defi ned by SnapNrack. The systems have been assessed to a maximum Over-Current Device (OC0) Protection level of 20 Amps. These systems have also been evaluated for a Oass A System Fire Class lflcatlon ror Low-Sloped and Steep-Sloped Roofs w ith Type 1 and Type 2 modules. System fire rat i ng was established both wit h and without the Skirt Assembly, making the slcirt optional to maintain system fire ratings. Modules were tested at a height of 5 inches off the test dedc which is cons idered a worst case condition ac cording to UL 2703. Certain components have also been evaluated for Wind-Driven Rain, per the requirements of UL S<Jbject 2582. for addftlonal details about Ultra Rall systems UL listing and to review a list or modules for whtch the sys tems have been tested, please see the rollowlng: https.//lq.Lforosoector.com/en/proHle?e-122609 Gerrell Washington Engineering Project Handler January 31, 2023 SnopNr ock 775 Fiero Lane.
