3.1.Snap north-south and east-west layout lines (chalk or dry line recommended) for the edge of the
array. Consult the Racking Construction Set for the Support spacing from module edge (Dim R).
(Note that the chalked lines will indicate the Support perimeter and not the module perimeter.)
3.2.Begin the array at the northeast or northwest corner. Building arrays starting with the south row
is strongly discouraged.
3.3.Place the first three or four Supports in their approximate locations east-west and then use the
Spacer Stick to set the Supports in the correct locations.
3.4.In the example below the western most Support roof pads must be lined up with north-south
snap line. North edge Support roof pads must align with east-west snap line. Leave the Spacer
Stick in place (
).

3.5.Place a long Ballast Tray inside the hoops of the second and third Supports. Roughly center the
Ballast Tray between the Supports. Locate the Ballast Tray slots closest to the pre-installed
Support rivet nuts and shift the Ballast Tray east or west as needed to align the rivet nuts with
the slots. This Ballast Tray connects the first two columns of modules.
A TRAY SHOULD ALWAYS BE INSTALLED BETWEEN TWO MODULES SO THAT THE COLUMNS
OF MODULES ARE CONNECTED TOGETHER.
