Step 9
Carefully fold up the support angle so that it makes
contact with the underside of the module rail. The
hole in the side face of the angle should be aligned
over the side track of the module rail.
The support angle connection to the side of the
module requires that you slide a 5/16" bolt along the
side track until it aligns with the hole in the end of the
support angle.
Do not tighten the bolt completely. Leave a little
slack so you can square up the frame at the end of
the installation.
Step 10
Use a tape measure and gap the module rails a
distance equal to the "center to center" intermediate
hole spacing. (Step 4)
Be sure that you are spacing from the centers of
both top tracks in the rails. You might have to loosen
the u-bolt Nylock nuts so that you can easily adjust
the rail assembly along the torque tube.
The racked modules and frame will be squared up at
the end of the mounting procedure.
Step 11
Make sure that the tracker is in the "stow" or nearly
horizontal position and that the elevation bar or
actuator has been installed.
Line up the module bolts into each track. You might
have to spin the bolt a bit so that the square shoulder
of the bolt line up in the slot. Push the module
forward and repeat the process with the other side of
the module.
Once the module is properly positioned on the rails,
tighten the serrated module nuts until they are finger
tight.
