Step 5: Attach Tilt Plate Mounting Channel
A. Place tilt plate mounting channels on the sides of the pole clamp assembly (Detail E).
B. Install 1/4" bolt, flat and flange nuts 6 places on both sides, tighten to 84 in-lbs. Note: placing the flange nut in
the “closed” side of the wrench to align with the bolt through the cutout will make it easier to start.
(Detail F) Dropped nuts cannot be retrieved very easily.
Step 6: Attach Tilt plates
A. Attach tilt plates, flanges facing to the outside using 3/8-16 X 1”bolts, flats, locks and nuts; position the tilt
plates with the top parallel to the ground (0°). Do not torque at this time, tighten only enough to hold firmly for
next assembly steps.
(Detail G).
Step 7: Attach Cross Rails to Tilt Plates.
A. Attach cross rails to the tilt plates, open sides facing to the inside, (CENTERED) using 3/8-16 X 1”bolts, flats,
locks and nuts. Torque to 20 ft-lbs.
(Detail H)
Step 8: Attach Panel Support Sub Assembly to Cross Rails
A. Lean the 124” or the 82”sub assembly against the cross rail (Detail I), lift the end up and slide sub
assembly onto both cross rails and place the seam where the 56” and 68” panel supports meet, centered
between the cross rails, for the
(STP-LCR/124HW) (Note: 56” section to be on the north side of the cross rails.)
or
22 7/8” from the end of the 82” panel support to the north side cross rail face for the (STP-LCR/82HW)
(Detail J) attach with 3/8-16 X 1” bolt, flats, locks and nuts, Torque to 20 ft-lbs (dry) (4) Places. (DETAIL K)
B.
(STP-LCR/124HW) Lift next panel up onto the panel supports on the north side; align mounting holes so
the inside panel edges are approximately 1” apart. Loosely install with 1/4 x 3/4 bolts, flat, lock and nuts.
Repeat with the panels on the south side.
C. Final adjust spacing of all the panels to be even and parallel, and Torque to 84 in-lbs (dry).
Step 9: Install Knee Brace Cross rail STP-LCR/82HW STP-LCR/124HW
A. Install the 3
rd
cross rail across the south side (open side facing the pole) (DETAIL L) Note: location is determined by
the final desired angle setting for the array, see (DETAIL M).
Step 10: Adjust Tilt Angle
Remove the lower two 3/8-16 x 1.0 bolts from the tilt plates and tilt the array to desired angle, the array
tilts in 10° increments from 0° to 60°. Re install 3/8-16 x 1.0 bolts and torque all six 3/8-16 x 1.0 bolts to
20 ft-lbs (dry) Note: to set to 60° one bolt set will need to be in the center position.
