Step 1
The modules get mounted to the rails using the
intermediate holes. Locate the intermediate
mounting holes on the frame of your module.
In general, they are placed from 7" to 16" in on the
long side (Length) when measured from the frame
edge short side (Width).
Each manufacturer has unique hole patterns. Your
mounting holes are made to accommodate either
1/4" or 5/16" module mounting bolts. The bolts are
supplied with your Wattsun Tracker.
Step 2
Identify your module mounting bolts and nuts from
the hardware kit. The module bolts are labeled and
are either 1/4" or 5/16" diameter.
Note that both the interior faces of the nut and bolt
are made to cut into the module frame. They do not
require any type of washer.
