A. Lay one of the PV modules on a flat surface, frame side up as shown in Detail F
B. Place one doubled and one single Module Support Rail assembly across the PV module with
the obround slots in the rails face down on the module frame, and the open side of the single
rail assembly facing towards the center of the module, as shown in Detail F. Make sure that
the 56” sections of the rail assemblies are on the same side of the PV module (also see note
on previous page about placement of the PV module wiring junction boxes). Place the PV
module in the center of the rail assembly and align the mounting holes of the module frame
with the obround slots on the Module Support Rails. Attach the rail assemblies to the module
frame using the 1/4" x 3/4" bolts, flat washers, lock washers and nuts. Tighten only enough to
hold firmly, do not fully torque at this time.
Note: On the doubled Module Support Rail assembly, the assembly is only bolted to the module
frame, using the mounting holes in the PV module’s frame, on the inside of the rail assembly – the
side facing the center of the PV module. The outer doubled Module Support Rail in the assembly
will be attached later.
C. Repeat Step 4 A and B with a second PV module, the second double rail assembly and the
second single rail assembly. However, you may want to have the PV module’s junction box on
the opposite side of the rail assemblies, or with a different polarity position on the rails, per the
note about junction boxes above. Make sure that the 56” sections of the rail assemblies are on
the same side of the PV module. Tighten only enough to hold firmly, do not fully torque at this
time. Set aside these two PV module and rail sub assemblies.
