Step 2:
Determine foot spacing
There are many combinations of bolting locations and brace overlap configurations to achieve foot
spacing’s for the angle(s) desired for your location, the following is a process to make that
determination to fit your requirements, or use the
general specification chart on page 5
.
A.
For the front to rear distance, loosely assemble the A frame section as shown below, adjust the rear leg
brace maintaining the minimum 6” overlap or more (“C”) to support the panels at the desired angle to
the sun and keeping the rear leg within 60° to 90° to the panel supports. With the “A” frame laying on
a flat surface measure the center to center distance between the U-feet to determine the front to rear
spacing for the footing.
B.
Keep the rear brace assembled at the overlap determined in prior operation,
preassemble
the second
pair and set aside.
C.
For the side-to-side footing of both “A” frames, the center to center spacing is equal to the center-to-
center distance of the mounting holes on the PV module you are using, See mount spacing diagram on
PAGE 5.
D.
If you are installing multiple UNI-GR mounts side-by-side
, leave a 1” space between the edges of the
modules on each mount. To determine the spacing between mounting feet, measure the distance from
the short edge of the modules to the mounting hole you are using. The recommended spacing
between mounting feet on adjacent mounts is two times the distance from the edge of the panel to
center of the mounting hole plus 1”. See the diagram in Step 1 of Final Assembly on page 8
