Step 1: Mounting And Grounding The Power Optimizers - SolarEdge SE3000H-US Installation Manual

Step 1: Mounting and Grounding the Power
Optimizers
For each of the power optimizers
1. Determine the power optimizer mounting location and use the power optimizer
mounting brackets to attach the power optimizer to the support structure (See
Figure 5). It is recommended to mount the poweroptimizer in a location protected
from direct sunlight. For frame-mounted power optimizers follow the instructions
supplied with the optimizers, or refer to
https://www.solaredge.com/sites/default/files/installing_frame_mounted_power_
optimizers.pdf.
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.
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.
3. Attach each power optimizer to the rack using M6 (1/4'') stainless steel bolts, nuts and washers or
other appropriate mounting hardware. A pply torque of 9.5 N*m / 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.
For mounting on a grounded metal rail: Use the provided 5/16'' stainless steel grounding star
l
washer between the railing and the flat side of the mounting bracket. T he grounding washer
should break through the anodize coating of the railing to ensure low resistive connection. Apply
torque of 9.5 N*m / 7 lb*ft. See Figure 5.
1 Not applicable to smart modules.
2 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. I t is not
intended or listed to be used as a general purpose grounding lug with other electrical equipment.
