Installing the Power Optimizer
Step 1, Mounting and Grounding the Power Optimizers
1
Use the power optimizer mounting brackets to attach the power optimizer to the racking, as
described below.
2
Determine the power optimizer mounting location.
3
If required, mark all mounting hole locations and drill the holes.
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.

en résulteraient peuvent endommager la optimiseur de puissance.
4 Attach each power optimizer to the rack using the 5/16'' or 1/4'' screws and washers.
5 For North America only - use the following methods to ground the power optimizer:

For mounting on a grounded metal rail: Use the provided 5/16'' stainless steel 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 torque of 9.5 N*m / 7 lb*ft.
