Page 10: Step 4: Connecting Pv Modules To Module Support Rail Assemblies
LTP HW Mount Series Step 4: Connecting PV modules to Module Support Rail assemblies: The LTP LCR/124HW mount, with the added High load Kit, utilizes three PV modules per column, two columns side by side. For assembly purposes, attach the middle PV modules only at this point, one to each pair of Module Support Rails, as shown in Detail F. - Page 11 LTP HW Mount Series A. Lay one of the PV modules on a flat surface, frame side up as shown in Detail F B. Place one doubled and one single Module Support Rail assembly across the PV module with the obround slots in the rails face down on the module frame, and the open side of the single rail assembly facing towards the center of the module, as shown in Detail F.

Page 25: Foundation Hole Guidelines
LTP HW Mount Series Foundation Hole Guidelines The suggestions below are recommendations only. It is the installer’s responsibility to validate foundation parameters prior to installation, as local geotechnical report may be required to assess soil conditions. We recommend consulting with a local engineer familiar with local regulations and build site requirements, including soil conditions, terrain, and load criteria (wind, snow, seismic). - Page 26 LTP HW Mount Series Installation Recommendations: Concrete to be min 3,500 PSI 1. Auger hole to minimum depth shown in foundation guidelines, + 6" for (#2). Drilled holes to be filled with concrete shall be cleaned to remove all loose cuttings. 2.
