• Pole Installation Zomeworks can only provide general guidelines for the design and installation of the mounting pole. Our recommended hole diameters and depths are based on “typical soils”. For installations in sandy or muddy areas, for tall mounting poles, or for any situation different than what is described in these instructions, you should consult a local structural engineer. - Page 4 Heavier steel pipe (sch 80 or sch 120) can be used as long as outer diameter is 6.625”. • Using the chart provided below, find the MINIMUM acceptable pole height above your • finished grade. The suggested pole height will provide approximately 28” of ground clearance with the largest module arrays installed.

6. If high winds or severe storms are expected, securing the rack in a horizontal position with straps is the best way to prevent damage. 7. Zomeworks Track Racks™ will move in the wind, much as trees do. This motion is expected and does not harm the tracker or its performance.
