Ifrequired,markthemountingholelocationsanddrillthehole.
CAUTION!
Do not drill through the power optimizer or through the mounting holes. The drilling vibrations can
damage the power optimizer and will void the warranty.
ATTENTION!
Ne pas percer à travers la optimiseur de puissance ou ses trous de fixation. Les vibrations qui en
résulteraient peuvent endommager la optimiseur de puissance.

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.

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.
