Page 4: System Overview
System Overview Parts Supplied by KB Racking® □ B00-01E-62 BarnRack Rail □ B00-02E-XX Roof Hook □ B00-04B Splice Plate □ C02-xxE Module Middle Clamp □ C02-xxE Module End Clamp □ M8 T-Bolt Lag Bolt/TEKS Screw □ M8 Serrated Flange Nut □... - Page 5 ⚠ ⚠ PLEASE READ THE FOLLOWING 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. Distance from gas lines and electrical equipment Solar panels should be a minimum of 3ft (0.9m) away, unless otherwise stated.

Page 6: Preparing For Installation
Preparing for Installation Ensure the surface of the roof is clear of debris and obstacles that may impair the installation of the system or the performance and safety of the installation team. Check and count that all parts and their desired quantities have arrived in the proper fashion. -
Page 7: How To Use Your Spacing Diagram
How to Use Your Spacing Diagram Your Spacing Diagram will indicate the following important dimensions: ROW SPACING (Distance between Hook rows, along corrugation) COLUMN SPACING (Dist. between Hook columns, across corrugation) PANEL SPACING (Distance between panel columns) Record the above numbers and do not confuse them. Figure 2 - Sample Spacing Diagram... -
Page 8: Installing Hook Profile
Installing Hook Profile Using the engineering drawings provided, mark the hook locations ensuring that they line up with the roofing ribs and the underlying purlin members. IMPORTANT The roof hooks are meant to be positioned on top of the rib profile in order to remove them from the water causeway when it rains. - Page 9 At the indicated locations, pre-drill a hole through the sheet metal to create a path for the fastener, as shown in Figure 4 - Predrill Sheet Metal. When fastening into thick metal purlin, it may be necessary to additionally predrill the path through the purlin for the screw. Figure 4 - Predrill Sheet Metal For wood structures, as well as metal, use the appropriate screws along with sealing washers to penetrate the roof and fasten into the purlin below.
- Page 10 Figure 5 - Hook Orientation Option 1 Figure 6 - Hook Orientation Option 2 IMPORTANT The hook profiles and hanger bolts must be spaced according to the engineering drawings and never at a greater spacing than as indicated. Please refer to Figure 7 on the following page to see the sample engineering drawing and specified dimensions.
- Page 11 Figure 7 - Sample Engineering Drawing Fasten the hooks to the roof, ensuring a water tight seal with the rubber sealing tape. The roof hook must not make direct contact with the metal roofing. Use water resistant caulking where necessary to eliminate to possibility of leaks.

Page 12: Installing Rails
Installing Rails The T-Bolts provided are used to connect the rails to the hook profiles. Feed the T-Bolt through the hook profiles' allotted slot as shown in Figure 8 below. Then position the rail above it and feed the head of the bolt through the rail slot. - Page 13 Each rail comes in 6.2 meter [20.34 ft] lengths. Rails can easily be cut to the required length when necessary. When securing two rails together, splice plates are used at the end of each rail and fastened together using the provided bolts and serrated nuts. Make sure to secure splice plates on the underside of the rails.

Page 14: Installing Panels
Installing Panels Begin at an array corner. Position it to its respective set of rails. If possible, start at the bottom of the roof and work your way up. ⚠ IMPORTANT Strong winds can lift panels. Solar panels cannot be left unsupervised without all FOUR (4) KB Konnect clamps torqued in place. - Page 15 (see example, Figure 5). IMPORTANT ® End clamp blocks provided by KB Racking designed to match your solar module thickness. This ensures the clamp sits flat. If end clamps do not sit flat, you have the incorrect block.
- Page 16 ⚠ IMPORTANT To prevent damage to solar panel and clamp, do not exceed recommended torque setting above. Do not use hammer drills, impact drivers, or long allen keys. ⚠ IMPORTANT When securing clamps, ensure panels do not slide and fall off roof. It is recommended that at least 2 installers install the first panel in each row.

Page 17: Grounding And Cable Management
Grounding and Cable Management Panels can be cabled as they are installed. Install grounding wires across each continuous row, once per rail extensions. Insert uninsulated grounding wire into each grounding lug. Each continuous row of panels is grounded once on the end of the rails IMPORTANT When bonded, any one panel OR group of panels can be removed without disrupting the bonding... -
