Frame-mounted power optimizers are mounted directly on the
module frame , regardless of racking system (rail-less or with rails).
For installation of frame-mounted power optimizers, refer to

.
The steps in this chapter refer to module add-on power optimizers. For smart

Step 3: Connecting Power Optimizers in Strings on page 25 Also refer to the
documentation supplied with the smart modules.
The power optimizer can be placed in any orientation.
If connecting more modules than optimizer inputs in parallel, use a branch
cable. Some commercial power optimizer models have a dual input.
Position the power optimizer close enough to its module so that their cables
can be connected.
Make sure to use power optimizers that have the required output conductor
length:
Do not use extension cables between a module and a power optimizer,
between two modules connected to the same optimizer, or between two
optimizers other than in the cases specified below.
You can use extension cables between power optimizers only from row
to row, around obstacles within a row, and from the end of the string to
the inverter, as long as the maximum distance is not exceeded.
