4. Use the following methods
(1)
to ground the power optimizer:
WARNING!
The metallic enclosure of the power optimizer must be grounded in
accordance with the requirements of the local and national codes.
AVERTISSEMENT!
L'enceinte métallique de l’optimiseur de puissance doit être mise à la terre en
accord avec les régulations locales et nationales.
For mounting on a grounded metal rail: Use the provided 5/16'' stainless steel
grounding star washer between the railing and the flat side of the mounting
bracket. The grounding washer should break through the anodize coating of the
railing to ensure low resistive connection. Apply a torque of 9.5 N*m / 7 lb*ft.

These methods have been evaluated by a nationally recognized testing laboratory as part of the optimizer
evaluation. The SolarEdge-supplied grounding lug kit has been evaluated only for use with SolarEdge power
optimizers. It is not intended or listed to be used as a general purpose grounding lug with other electrical
equipment.
