17.
Install the Short Ballast Trays at either end of the row using two ¼-20 x 0.5” serrated flange bolts
and the pre-installed riv nut to attach the Long and Short Ballast Trays together. Either the slots
or through holes at the end of the Long Ballast Tray may be used to connect the short and long
trays. Ensure that the slots in the Short Ballast Tray align with the Supports bolts on the last
Support in the row. Install a serrated flange nut onto each Support bolt (
). Nuts and
bolts must be torqued to 4 ft-lbs.
18.
Install required ballast into the Ballast Trays and bend up the tabs at the ends of the row.
Figure 7 Attach Short Ballast Trays
Step 4: Install Array Row-By-Row
1.
Place two Standard Supports for each module at their approximate final resting location. If the
row being built is the last row in the array, use North Supports.
2.
Connect module Claws to lower mounting holes on the Standard Support of the previous row.
Finger-tighten bolts.
3.
Tilt module down and adjust the placement of the previously spaced Standard Supports to
connect module Claw to the high side of the Standard Support. Finger-tighten nut and bolt. Be
sure to align the outer Standard Support pads with North-South snap line.
4.
Tighten all four mounting hardware to 8 ft-lbs of torque.
5.
Repeat Steps 1 through 4 for remainder of the row.
6.
Install Long Ballast Trays, Short Ballast Trays and ballast blocks as done in the previous row.
7.
Complete the array by constructing row-by-row until the north array edge. The north row in the
array utilizes North Supports to secure the high side of the module. In some cases a North
Double Capacity Support may be required based on the project’s design criteria. If the project
utilizes North Double Capacity Supports Ballast Trays are installed in both the inclined position
and flat position of the Supports in a similar fashion to the south array construction.
See note 17
Hardware is required where
Long Ballast Trays and Short
Ballast Trays overlap
