Figure 5: Power optimizer installation and grounding using a grounding plate
For mounting on un-grounded structures (such as a wooden structure): If
the star washer or the plate cannot be used, use the SolarEdge grounding
lug (purchased separately)with an equipment-grounding conductor
according 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. See
Figure 6
