If roof/building edge has a fall distance of 10ft (3m) or greater, Appropriate safety measures must be taken (i.e. harnesses) for installation of panels closer than 6.5ft (2m) to roof edges or skylights. NOTE: Please note that KB Racking Inc. requires all arrays to be no ®... -
Page 7: Installing The Rails
Installing the Rails Before you begin, ensure you have the following documents provided separately: Layout Diagram, Rail Table and Spacing Diagram. Figure 1 – Use your Rail Table to determine which size of Rail to use Place your first Rail for an array. Refer to your Rail Table and Layout Diagram (Figure 1). - Page 8 Continue installing rows of Rails as required. Use your Rail Table and Layout Diagram to determine specific quantities and combinations of Rails. Install Rail Splices to connect Rails. Equally space two Rails within a Splice. Use the pre-punched holes on the Splice to align and install 4x TEK Screws (Figure 4 and Figure 5).

Page 10: How To Use Your Spacing Diagram
How to Use Your Spacing Diagram Your Spacing Diagram will indicate the following important dimensions: E/W SUPPORT SPACING (E/W distance between Supports) INTER-SUPPORT SPACING (inter-row distance between Supports) N/S RAIL SPACING (N/S distance between Rails) INTER-ROW SPACING (E/W distance between rows on Rail) END SPACING (E/W distance between edge of rail and first Support) ROW SPACING (E/W distance between similar points) Record these numbers and do not confuse them. -

Installing Module Supports Figure 10 - Installing Module Supports Note: The steps below outline how to install the above configuration of E/W and single-panel bays. You can use your layout diagram to determine which steps/configurations are relevant to your installations. Mark the End Spacing at the West edge of a Rail (Figure 11). - Page 12 Click-in a Top Support at the distance obtained in Step 5, with your spacing stick. Ensure that the Top Support mirrors the one installed in Step 4, as shown in Figure 13.

Page 14: Installing Double Ballast Trays
Installing Double Ballast Trays Double ballast trays are only required wherever they are shown on the Ballast Layout (see example, Figures 25). Install Ballast Trays under PV panels, top-down, onto rails (see example illustration, Figure 21). Refer to the Shading Diagram, provided separately, for configuration requirements. - Page 15 How to Use Your Ballast Layout Ensure you have the Ballast Layout and Shading Diagram documents, both provided separately. The Ballast Layout shows the combinations of stones required at each rail, to ballast the adjacent panels. The Shading Diagram shows sample arrangements of stones (Figure 26). Figure 21 –...

Page 16: Installing Pv Modules
Support and use a 5mm Allen key to secure the Clamp (Figure 27 to Figure 29). IMPORTANT End Blocks provided by KB Racking® are designed to match your PV Module thickness. This ensures the clamp sits flat. If end clamps do not sit flat, you have the incorrect block. - Page 17 IMPORTANT To prevent damage to solar panel and clamp, do not exceed recommended torque setting below. Do not use hammer drills, impact drivers, or long Allen keys. Continue installing adjacent PV modules. To ensure proper clamping, pull panels firmly together while installing (see examples, Figure 30 and Figure 31). Torque KB Konnect to 8.3Nm (6.1 ft-lb).

Installing Cable Systems After all modules are in place, string cables can be put into the middle notch of the Module Top Supports and Bottom Supports. Tip: Rails can be used as cabling channels either under or to the side of the supports, within the rail channel. -
Page 20: Installing Windshields
Installing Windshields NOTE: Windshields are only required on Top Supports that are at the edge of an array. In other words, Windshields are only required at single-panel bays. At the end of a row place the windshield flat against the Top Support. Flanges face away from supports. -
