Step 1, Mounting The Power Optimizers - SolarEdge Power Harvesting System Installation Manual

SolarEdge Installation Guide for Three Phase Inverters – EU – Version 1.5
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.
