Step 2 – Attaching the APS Microinverters to the
Racking or the PV Module Frame
A.
Mark the location of the Microinverter on the rack, keeping in
mind the PV module junction box or any other obstructions.
B.
Mount one Microinverter at each of these locations using
hardware recommended by your module racking vendor.
C.
GROUNDING WASHER:
If using the appropriate grounding
washer (check with a licensed electrician); attach the grounding
washer between the frame and the Microinverter.
WARNING:
Prior to installing any of the Microinverters, verify that
the utility voltage at the point of common connection matches the
voltage rating on the Microinverter label.
