•
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. It is strongly recommended that the
pole height meet our minimum specifications.
•
The
MINIMUM
recommended hole
depth is 1/3 the total length of the
pole – 1/3 in the ground, 2/3 above
the ground.
For example: 8' above grade, 4'
below grade – 12' total length.
•
Center pipe in hole, use a level or
plumb line to insure pipe is vertical.
•
Fill the hole with concrete (3000 psi
minimum strength), and recheck
verticality.
•
The pipe may be filled with concrete
for added strength (only to
approximate ground level)
•
Allow concrete and pipe to set for a
MINIMUM
of 36 hours before
installing Track Rack™
Rack Assembly Instructions
Attaching Gimbal to Pole
•
Place Gimbal on top of pole.
•
Orient Gimbal so that 3/4” x 2” bolts are facing
true
south (adjust for magnetic declination)
•
Tighten bolts to 75-100 ft-lbs torque in turns
to insure both are tight.
3/8” x 9” HEX BOLT CAN BE INSTALLED TO PROVIDE
ADDITIONAL RESISTANCE TO UPLIFT AND TWIST.
THIS MAY ALSO BE A REQUIREMENT OF THE
PERMITTING AUTHORITY.
•
With Gimbal oriented properly (set bolts pointed true
south), use pre-drilled 7/16” holes as a guide to drill through the pipe on both sides.
•
Slide the 9” hex bolt through the Gimbal and pipe, install flat washer and tighten first
hex nut. Tighten second nut against first.
