Instructions for using photovoltaic modules
Other option can be:
Materials (to be supplied by the installer of the system).
(1) Lay-in Grounding Lug (Outdoor Rated), Ilsco GBL-4DBT (or equivalent,
UL listing required).
(1) #10-24 1/2 Stainless Steel (SS) Self-Threading Machine Screw.
(1) #10 SS Double Bifurcated (Toothed) Lock Washer between the Nut
and the Aluminum Frame.
(1) #10-24 SS Nut.
Procedure:
Use one of the two labeled grounding holes provided on the modules.
The aluminum frame is anodized so it is essential to remove the anodized
surface finish around the hole in the local area beneath the base of the
lug to get good connectivity between the ground lug and the module
frame. You can use emery paper or an abrasive grit wheel to lightly
scrape the surface. Place the lug on the surface of the module, and add
the self-threading screw creating a threaded hole and tighten. Put the
lock washer then the nut on the screw on the inside of the frame and
tighten to a minimum torque of 20 inch-pound.
