Installation Overview <br /> Install Roof Attachments <br /> • Install appropriate roof flashing and/or standoff for roof type. <br /> • Attach L-Feet to flashing or standoff. <br /> Prepare Rail Connections <br /> • Insert splice into first rail, then secure with Grounding Strap and <br /> self-drilling screw. <br /> • Slide second rail over splice, then secure with opposite end of <br /> Grounding Strap and self-drilling screw. <br /> Mount & Ground Rails <br /> • Attach rails to L-Feet and level rails. <br /> • Install one Grounding Lug per row of modules. <br /> • Connect Grounding Lug to grounding conductor. <br /> Install Modules & Clamps <br /> • Install first module using End Clamps and Grounding Mid Clamps. <br /> • Install additional modules using Grounding Mid Clamps. <br /> • Finish row with a second pair of End Clamps. <br />Testing & Certification <br />The IronRidge Integrated Grounding <br />System has been tested and certified to <br />UL 2703 by Intertek Group plc. <br />UL 2703 is a proposed UL standard <br />for evaluating solar module mounting <br />and clamping devices. It ensures these <br />devices will maintain strong electrical and <br />mechanical connections over an extended <br />period of time in extreme outdoor <br />environments. <br />The testing process closely mirrors that <br />of UL 1703, the solar module testing <br />standard, including temperature and <br />humidity cycling, electrical and mechanical <br />load testing, and manufacturing quality <br />reviews. <br />1 <br />2 <br />3 <br />4 <br /> © 2013 IronRidge, Inc.
