请注意:此版本的所有临时修订版将在您购买时提供。用于平板光伏组件和Panel SUL 27031 Scope1的安装系统、安装装置、夹紧/固定装置和接地片。1这些要求包括机架安装系统、安装接地/连接组件以及特定（制造商/型号名称）平板光伏组件和面板的夹紧/固定装置，这些平板光伏组件和面板符合《平板光伏组件和面板标准》（UL 1703），拟安装在建筑物上或与建筑物集成，或为独立式（i。 e、 ，不附在建筑物上），符合国家电气规范、ANSI/NFPA 70和建筑模型规范。根据本标准评估的系统、组件和/或装置可用于接地和/或安装符合UL 1703的光伏组件，前提是已评估特定模块或框架的连接/接地情况，或已评估该模块与评估的系统、组件或装置的安装情况。1.2这些要求包括用于最大系统电压为1000 V的光伏模块系统的机架安装系统和夹紧装置。1.3这些要求仅包括机架安装系统、夹紧装置、与接地/粘接路径有关的固定装置、机械强度和材料适用性。 1.4这些要求不包括:a）用于接收阵列电输出的设备，如功率调节装置（逆变器）和电池。b） 太阳跟踪器或跟踪器机构（除非UL 3703《太阳跟踪器调查大纲》以及与UL 3703结合使用的特别指示）。c） 用于在集中阳光下工作的电池组件。d） 光学集中器。e） 组合光伏热组件或面板。f） 作为该部件的正常功能，用于承载电流的设备，如汇流箱、接线盒（接地接线盒除外）、电线槽和容纳带电部件的外壳。 参见《平板光伏组件和面板标准》（UL 1703）或《分布式能源用逆变器、转换器、控制器和互连系统设备标准》（UL 1741）。g） 接地棒和接地棒附件。h） 国际建筑规范的机械和结构要求。注:IBC和其他型号代码可能有其他要求。例如，遵守IBC将需要开发荷载组合，包括使用ASCE 7的静荷载、雪荷载、风荷载和地震力。这些荷载需要在三个正交方向上施加，系统的抗荷载元件需要充分支撑施加的荷载。

Please note: All interim revisions for this edition available at time of your purchase will be included.Mounting Systems, Mounting Devices, Clamping/Retention Devices, and Ground Lugs for Use with Flat-Plate Photovoltaic Modules and PanelsUL 27031 Scope1.1 These requirements cover rack mounting systems, mounting grounding/bonding components, and clamping/retention devices for specific (manufacturer/model designation) flat-plate photovoltaic modules and panels that comply with the Standard for Flat-Plate Photovoltaic Modules and Panels, UL 1703, intended for installation on or integral with buildings, or to be freestanding (i.e., not attached to buildings), in accordance with the National Electrical Code, ANSI/NFPA 70 and Model Building Codes. Systems, components and/or devices evaluated under this standard may be used to ground and/or mount a PV module complying with UL 1703 when the specific module or frame has been evaluated for bonding/grounding or the module has been evaluated for mounting with the evaluated system, component or device.1.2 These requirements cover rack mounting systems and clamping devices intended for use with photovoltaic module systems with a maximum system voltage of 1000 V.1.3 These requirements cover rack mounting systems, clamping, retention devices pertaining to ground/bonding paths, mechanical strength, and suitability of materials only.1.4 These requirements do not cover:a) Equipment intended to accept the electrical output from the array, such as power conditioning units (inverters) and batteries.b) Solar trackers or tracker mechanisms (except as specifically directed as to be utilized by the Outline of Investigation for Solar Trackers, UL 3703 and in combination with UL 3703).c) Cell assemblies intended to operate under concentrated sunlight.d) Optical concentrators.e) Combination photovoltaic-thermal modules or panels.f) Equipment intended to carry current as a normal function of that component, such as combiner boxes, connection boxes (other than connection box for grounding), wireways and enclosures housing live parts. See the Standard for Flat-Plate Photovoltaic Modules and Panels, UL 1703 or the Standard for Inverters, Converters, Controllers and Interconnection System Equipment for Use With Distributed Energy Resources, UL 1741.g) Ground rods and ground rod accessories.h) The mechanical and structural requirements of the international building code.Note: The IBC and other model codes may have additional requirements. As an example, compliance with the IBC will require development load combinations which include dead, snow, wind and seismic forces using ASCE 7. These loads will need to be applied in three orthogonal directions and the load resisting elements of the system will be required to adequately support the applied loads.
