3.17.Reference the Racking Construction Set to determine which length Ballast Tray is required.
Install Ballast Trays to the pre-installed rivet nuts on the Supports by centering each Ballast Tray
between two modules. For end of row Ballast Trays install the tray centered on the module.
The Ballast Tray may be shifted east or west to align with the closest slots. All ballast trays must
be secured to two supports. Use the Spacer Stick to ensure the high side of the Supports is
properly spaced. Thread a Bolt into each of the pre-installed Rivet Nuts and torque to 8-10 ft-lb
(96-120 in-lb).
NOTE: All
end of row Ballast Trays must be bolted to both the first and second support in from the
array edge. End trays do not need to be flush with the edge of the module for all none north array
edges. Where a long Ballast Tray is specified at the end of the row it should appear flush with the
module. When a short Ballast Tray is specified at the end of the row it should appear centered on
the module.
NOTE:
Do
not
fasten Long Ballast Trays together where they overlap in midair. Secure Ballast Trays
together only when two Ballast Trays overlap on the same Support (all end of rows).
Note: Torque all Claw bolts after module claws
have been attached to the Supports. Pre-
mature torqueing will result in a loss of torque.
Torque all Claw bolts to
8-10 ft-lb (96-120 in-lb)
