3. Overview of assembled tracking system 3.1 Axes of motion Assembly Instructions InteliTrack 3000 System The system is configured to move in two axes to track the sun. The motion around the elevation axis (Figure 3) tilts the array toward the north in winter (in the northern hemisphere) and more nearly horizontal in the summer. Figure 3: Elevation axis Sedona Solar Technology 16 April 2013 4
The motion of the radial axis moves the panels to track the sun from east to west through the day. Figure 4: Array at summer position Figure 5: Array at winter position Sedona Solar Technology 16 April 2013 5
3.2 Array configuration Up to six frames can be joined together to make a single array or rail. Each array will have one West frame (Figure 6), one East frame (Figure 7), and up to four Center frames (Figure 8). Note the differences in the corners where each rail meets a crossbeam.

Note: Rail end brackets will have different spacing for the crossbeams at both ends of the frames. Rails mating to end crossbeams install as shown in Figure 17. Rails mating to middle crossbeams install as shown in Figure 18. 4.4.4 Using two ratchet straps, secure the southern end of each crossbeam to the mounting posts to prevent crossbeams from moving during installation of the bottom frame rail. 4.4.5 Mount the bottom rail to the crossbeam using bolts as shown in Figures 19 and 20. Make sure the grommets face inside the frame. 4.4.6 Flip the frame so that the installed rail is now on the high side, and secure the frame with ratchet straps. 4.4.7 Install the top rail in the same way. 4.4.8 Using a tape measure and a square, check to make sure that the frame is square to within 0.25.
