Grounding Method - S-Energy SN245P-10 Installation Manual

8. Grounding Method

For preventing electric shock and fire, the frame of PV module shall be
grounded properly. [Please be sure to remove a coated portion when grounding,
because the PV module aluminum frame is coated with anodizing.]
[Before installation]
Configuration Size and material
A M4 Bolt
B M4 Star washer
C M4 Plat washer
D M4 Cup washer
E Grounding wire
F M4 Plat washer
