Page 16: T Assembly
Assembly Standing seam Place the PowerClamp on the standing seam making sure it hugs the rib. Tighten set screw(s) so the clamp is secure, but leave it slightly lose to allow for later adjustment. Insert the hex screw through the slot of the L-Foot and into the PowerClamp. - Page 17 Insert T-Bolt through the L-Foot slot and into side channel of rail. Turn T-Bolt 90º clockwise so that the mark at the end of the T-Bolt is pendicular, indicating proper alignment. Torque to 25.8 ft-lbs (35 Nm). Due to thermal expansion, we recommend placing a gap of 1.25"-2"...
- Page 18 Ensure that the slot on the bottom of the T-Bolt is perpendicular to the rail, indicating proper alignment. Torque to 25.8 Ft-lnbs (35 Nm). Using the CrossRail Microinverter and Optimizer Mounting Kit hardware from K2 Systems, attach your chosen device to the top channel of Cross- Rail. Torque to 10.3 ft0lbs (14 Nm).
- Page 19 Optional Using the standard End Clamps, attaach the Array Skirt to the top channel of CrossRail. Torque clamps to 10.3 ft-lbs (14 Nm). Place Array Skirt into channel ensuring tabs lock into channel. Place clamp into rail channel. Place Add-On over clamp and into rail channel. Insert clamps (mid and end) into rail at approximate module mounting locations.
- Page 20 Push zip tie up into leash channel located on bottom of Yeti Clamp. Slide clamp into rail channel with bolt facing outward. Leave enough room for the module to be placed. Place the module flush to end of rail. Pull leash toward you so the clamp slides over module frame. Torque to 12 ft-lbs. Use your hand to ensure the Yeti Clamp is fully engagaed with the frame of the module as shown in the image.
- Page 21 Tighten end clamps to module at spcified locations per PV module manufacturer's guidelines. Torque to 10.3 ft-lbs. Ensure clamp sits flush against module frame. Tighten mid clamps to module at specified locations per PV module manufacturer's guidelines. Torque to 12 ft-lbs. Ensure modules are flush against the clamp.
- Page 22 Push pins of appropriate end cap into end of rail. Insert the MK3 Slot Nut of the preassembled Everest Ground Lug into top channel of CrossRail. While slightly lifting the plastic tabs, rotate 90º clockwise to engage into rail channel. Ensure bonding teeth are perpendicular to the rail channel.
- Page 23 To attach WEEB Lug 10.3, insert T-Bolt into side channel of CrossRail and rotate clockwise 90º. Tighten serrated hex nut to 15 ft-lbs (20.3 Nm). Insert a #6 or #8 AWG solid copper wire and tighten terminal screw to 5 ft-lbs (6.7 Nm). Front and rear rails can be offset to facilitate rail alignment and/or hide rail.
