Figure 6: 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 7 .

5. Verify that each power optimizer is securely attached to the module support
structure.
6. Record power optimizer serial numbers and locations, as described in Reporting and
Monitoring Installation Data on page 65.
