AZ-225 Install Manual

BUILDING THE FRAME AND RACKING THE MODULES:
DO YOU MOUNT ONE PIECE AT A TIME OR BUILD SUB-ARRAYS?
Module Rail & Support Angle Detail
From the bottom up the Procedure is:
Bolt > Support Angle > Tube > Rail >Washer > Nut
One installer, one piece at a time approach.
Modules are being used to “square-up: the frame.
Notice how the modules overhang the Rails.
Sub-Array Approach: Requires a lot of people power.
Notice that the rails bolt to the intermediate module holes.
Lift by the tracker rails only, not the module frames!
Lifting and bolting the sub-array onto the tube.
Typically a 3-person job: 2 lifters, 1 bolter.
Lift by the tracker rails only, not the module frames!
The “one piece at a time” approach can get very tiring. The
installer is working with their arms and hands above their head.
We encourage installers’ to wear a Hard Hat.
Leave all frame and module bolts “finger tight.” Once you finish
the frame building and module mounting, you can go back and
“square up” the array. Then tighten all nuts with a wrench.
NOTE: If you ever “under populate” the array frame, leave
any unused space at the top of the frame. If the frame is
not totally filled out, then the greatest weight should be on
the lower sections of the frame.
