Framed and frameless PV - Modules
Assembly sequence of the flat roof:
First, the angle brackets must be assembled by
loosely fastening the T-Bolt, nut and washer.
Hardware must remain loose at this time to allow
for base rail connection.
See Figure 2.1
Next fasten the angle brackets to standoff/
flashing system of your choice. The torque rating
can vary depending on the size of the hardware
used from the standoff/flashing connection to
the angle bracket.
Typical Torques: M10 = 25 ft. lbs.
M12 = 45 ft. lbs.
See Figure: 2.2
Base mounting rails are fastened to the serrated
angle bracket by inserting the T-Bolt head into
the serrated mounting rail slot which are located
on both sides of the ST-AK 120 x 90 rail.
T- Bolts must be turned clockwise to fasten.
Check for proper alignment of T-Bolts in
mounting rail slot. The line on the back of the
T-Bolt must be perpendicular to rail.
See figures: 2.3, 2.4 & 2.5
(Torque: 6 to 8 ft. lbs.)
Connecting rails:
To join system rails to one another,
insert splice into rail until the rivet in
the middle of the splice stops the
insertion.
See Figure 3.1
Next, slide the other system rail onto the splice and push rails together until
the rivet on the splice stops the movement. ½” gap or separation between
rails is required for thermal expansion.
See Figure 3.2
Continue fastening base rails as described in sections 2.3 to 3.2 above.
