2. 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.

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.

L'enceinte métallique de l’optimiseur de puissance doit être mise à la terre en accord avec

les régulations locales et nationales.
