For mounting on rails with sliding nut fasteners: If the star washer cannot be used, use the
l
SolarEdge grounding plate (purchased separately) between the railing and the flat side of the
mounting bracket. A pply torque of 9.5 N*m / 7 lb*ft.

For mounting on un-grounded structures (such as a wooden structure): If the star washer or
l
the plate cannot be used, use the SolarEdge grounding lug (purchased separately) with an
equipment-grounding conductor a ccording to the supplied instructions. The grounding terminal
accepts a wire size of 6-14 AWG, and must be sized for equipment grounding per NEC 250.122
requirements. Tighten the screws connecting the power optimizer to the frame and the
grounding terminal screw. Apply torque of 9.5 N*m / 7 lb*ft.
5. Verify that each power optimizer is securely attached to the supporting structure or the module.
NOTE
Record power optimizer serial numbers and locations, as described in Providing Installation
