Step 1, Mounting the Power
Optimizers
NOTE:
If you are installing modules with embedded power optimizers, then skip to
Step
3, Connecting Power Optimizers in
Strings
on page 22.
Determine the mounting location of each power optimizer. The power
optimizer should be mounted in a place where it can be mounted
securely using both mounting holes. It must also be located near
enough so that the power optimizer can connect to a single PV module
(for the OP250-LV, OP300-MV, OP400-MV, PB250-AOB and PB350-
AOB models) or the power optimizer can connect to up to four PV
modules for the PB250-TFI and PB350-TFI models, per your plan.
Mark all mounting hole locations.
Each power optimizer must be attached to the rack using both mounting
holes.
Drill the holes.
CAUTION:
Do not drill through the power optimizer or through the mounting holes. The
vibrations created by the drill can damage the power optimizer.
Mount one power optimizer at each location using M8 screws and
washers.
Verify that the power optimizer is securely attached.
