Mounting Instructions - CanadianSolar CS3U-P Installation Manual

GROUNDING METHOD: BOLT + TOOTHED NUT + CUP WASHER.
To fix the wire between the
flat washer and cup washer,
place the cup washer
(concave side up) between
the frame and the wire.
 A grounding kit containing an M5 (3/16") SS cap bolt, an
M5 (3/16") SS flat washer, an M5 (3/16") SS cup washer,
and an M5 (3/16") SS nut (with teeth) is used to attach
copper grounding wire to a pre-drilled grounding hole
on the frame (see image above).
 Place the wire between the flat washer and the cup
washer. Ensure that the cup washer is positioned
between the frame and the wire with the concave side
up to prevent galvanic corrosion. Tighten the bolt
securely using the SS toothed nut. A wrench may be
used to do this. The tightening torque is 3-7 Nm (2.2-5.2
ft-lbs).
