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 for the torque tube under high loading. 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, any racking
structure shall not higher than frame C side.
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”) or M8 X 1.25 (5/16”) 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 for 10 X 7 mounting
hole, M8 X 1.25 (5/16”) for 14 X 9 mounting hole,
depending on bolt class.
