D. Drop eight 3/8” x 1” bolts with flat washers into the appropriate slots in order to bolt the Module
Support Rails down to the Cross Rails as shown in Detail N. There will be three bolts on each side of
the doubled Module Support Rail. Add the bottom flat washers, lock washers and nuts, finger tight.
Check the center gap spacing and adjust if necessary. Make sure that the Module Support Rails are
square to the Cross Rails, and torque the 3/8” x 1” bolts to 20 ft lbs.
Detail N:
E. Repeat A through D above for the second Module Support Rail/PV module assembly on the other
side of the pole, again making sure that the doubled Module Support Rail is towards the inside, that
the 56” sections of the support rails are on the north end, and that the PV module’s junction box is in
the proper location.
F. Lift the next PV module (#3 of the six) up onto one of the Module Support Rail assemblies on the
north side (again with the module’s junction box in the proper location). Align the mounting holes so
that the gap between it and the center module is approximately 1”. Loosely install with 1/4" x 3/4"
bolts, flat washers, lock washers and nuts. Repeat with the fourth module on the other side of the
pole, north end, then repeat again with the remaining two PV modules on the south sides of the two
columns. All module wiring junction boxes should be checked for proper location.
G. Do a final adjustment of all of the spacing of all the PV modules to be even and parallel, and torque
the 1/4” bolts to 84 in lbs.
