6.4 MOUNTING METHODS WITH SINGLE-AXIS TRACKER
The bolts and clamps used in this section should follow
the requirements in 6.1 and 6.2.
Under any conditions the junction box should not
become in contact with the subjacent racking structure
except torque tube. For any single axis tracker
installation method with portrait one row, bearing
house cannot be allowed to locate in junction box
position.
If any racking structures, especially bearing house,
have to be located under the modules, the gap H
between the frame and the racking structure should be
at least 25mm.
If your tracker design cannot meet the above distance
requirement, please contact Canadian Solar technical
support department in writing for advices.
Tracker 1P Bolting method
Install and tighten the module clamps to the mounting
rails using the torque stated by the mounting hardware
manufacturer. M6 X 1 (1/4”) bolt and nut are used for this
bolting method.
Tightening torques should be 6~9 Nm (4.5~6.6 ft-lbs)
M6 X 1 (1/4”) coarse thread bolts, depending on bolt
class.
