Figure 4 Placing the Ballast Tray onto Supports between modules.
3.6.Place a long Ballast Tray inside the hoops of the first and second Supports. Reference the
Racking Construction Set to determine the module overhang from the center of the Support
(Dim R). Align the Ballast Tray to the first Support so that the Ballast Tray overhangs the
Support nearly as much as the module (only on north array edges where the ballast tray acts as
a wind deflector)
3.7.Install the Ballast Trays to the pre-installed rivet nuts on the Supports using the nearest slots.
The Ballast Trays may be shifted east or west to align with the slots. Ballast Trays must
overlap
on the second Support. (

3.8.Install a ¼-20 serrated bolt on each pre-installed rivet nut. Torque all ¼-20 serrated bolts to 8-10
ft-lb (96-120 in-lb). Use the Spacer Stick to keep the Ballast Tray perpendicular to the Supports
while maintaining spacing between Supports. (Note there are three bolts required to connect a
tray to each individual support, one fastener per slot).
