26 Step 1: Mounting and Grounding the Power Optimizers
CAUTION!
Drilling vibrations may damage the power optimizer and will void the
warranty. Use a torque wrench or an electric drill with adjustable clutch that
meets the mounting torque requirements. Do not use impact drivers for
mounting the power optimizer.
Do not drill through the power optimizer or through the mounting holes.
ATTENTION!
Les vibrations résultant du perçage peuvent endommager l'optimiseur de
puissance et annulera la garantie. Utilisez une clé dynamométrique ou une
perceuse électrique avec embrayage adaptable compatible avec les
moments indiqués. Ne pas utiliser des tournevis à percussion pour fixer
l'optimiseur. Ne pas percer à travers l'optimiseur de puissance ou ses trous
de fixation.
3. Attach each power optimizer to the rack using M6 (1/4'') stainless steel bolts, nuts
and washers or other appropriate mounting hardware. Apply torque of 9-10 N*m /
6.5-7 lb*ft.
For 3NA series power optimizes, SolarEdge recommends mounting the power
optimizer on a rail with the smooth side facing out, so that the power optimizer
body will prevent its rotation.
4. Use the following methods
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.
(1) 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.
