Figure 6-2: Setting the Tilt Angle
Step 5: Now return and tighten mounting hardware.
Step 6: Adjust the Tilt Angle of the Rack
A. Return and tighten each set of the 3/8” mounting hardware, securing the
Module Rails to the Strongback.
B. Return and tighten each set of 1/4” mounting hardware, securing the PV
Modules to the Module rails.
To adjust the tilt angle, loosen the Pivot Bolt hardware and removing the Support
Arm upper hardware attaching the Support Arm to the Strongback. Use great care in
this procedure as it can be dangerous if the procedure is not completed as described
with a minimum of two people. (See Figure 6-1)
A. While one person holds the south edge of rack, the other loosens the Pivot
Bolt and removes the upper 3/8” or 1/2” hardware attaching the Support Bar
to the Strongback.
B. Tilt the rack to the desired elevation angle (15°, 25°, 35°, 45°, 55°, or 65°)
and re-attach the Support Bar to the Strongback placing the 3/8” or 1/2”
hardware in the appropriate hole matching the desired elevation.
Torque all at 32-34 ft.-lbs.
Torque all at 6-8 ft.-lbs.
(See
Figure 6-2)
Torque at
32-34 ft.-lbs. for 3/8” hardware or 72-80 ft.-lbs. for 1/2” hardware.

Figure 6-1: Preparing to Adjust the Tilt Angle
CAUTION:
Do not attempt to
remove the Pivot
Bolt during tilt
adjustments!
Removal could
lead to serious
personal injury or
death. Adjustments
are made with the
Pivot Bolt
hardware loosened
but in place.
CAUTION:
This is a two
person activity. As
the Pivot Bolt is
loosened and the
Support Bar
hardware is
removed, the rack
is heavy and
unstable. The rack
must be held in
place by one
person while the
second person
loosens and
removes the
hardware and then
re-installs/tightens
the hardware back
in place. Failure to
do so could lead
to serious
personal injury
and damaged
components.
CAUTION:
Be certain to re-
tighten all Module
Rail and PV
Module mounting
hardware and
torque to the
specified values.
Failure to do so
could lead to
structural failure,
damaged
components
and/or serious
personal injury.
