Tech Brief <br />9OSVROKJ-XU[TJOTMLUX+\KX_'VVROIGZOUT <br />The UFO family of components eliminates the need for <br />separate grounding hardware by bonding solar modules <br />directly to IronRidge XR Rails. All system types that feature <br />the UFO family—Flush Mount, Tilt Mount and Ground <br />Mount—are fully listed to the UL 2703 standard. <br />UFO hardware forms secure electrical bonds with both the <br />module and the rail, resulting in many parallel grounding <br />paths throughout the system. This leads to safer and more <br />reliable installations. <br />UFO Family of Components <br />;TO\KXYGR,GYZKTOTM5HPKIZ;,5 <br />The UFO securely bonds solar modules to XR <br />Rails.
