5.2 Grounding
5.2.1 Chint Solar modules use an anodic oxidized aluminum frame to resist corrosion. So the
frame of modules should be connected to the equipment grounding conductor to prevent thunder
and electrical shock. The grounding device should fully contact with the inside of the aluminum
alloy, and penetrate the surface of the frame oxidation film.
5.2.2 Chint Solar recommends using the following methods to ground modules properly:
Figure i
Grounding the aluminum frame with copper wire
a) The grounding requirements must be checked in accordance with the applicable
regulations and standards before work is started.
b) Use the marked 5.5 mm grounding holes to ground the anodized frame. Use one M5 nut,
two M5 cut washers, one M5 plain washer, one M5 spring washer, and one M5 bolt and the
copper wire. All nuts, bolts, and washers are type M5 and should be made of stainless
steel (Fig. i).
c) Put the bolt through the cup washer and wrap the copper wire around the bolt. (Note that
the copper wire cannot be attached directly to the aluminum.)
d) Put the bolt through the cut washer and then through the hole in the aluminum frame.
e) Add the spring washer and nut on the other side of the bolt and tighten to secure all parts.
