The Enphase Frame Mount bracket comes in two sizes, 35 mm (EFM- 35 MM) and 40 mm
(EFM-40MM), depending upon the thickness (depth) of the PV module frame.
•
Place the bracket clamp over the edge of the module frame, as shown in the following
figure, on the deeper frame side of the PV module.
•
Thread the cap bolt into the threaded insert on the bracket, then slide the IQ8
Commercial Microinverter slot onto the bolt.
•
Slide the microinverter unit onto the bracket clamp. The bolt now holds the frame
mount to the bracket clamp. The microinverter mounting flange should be on the
outside of the module frame, as shown in Figure 16.
•
With a 13 mm or 1/2-inch socket wrench, tighten the cap screw until you reach a
torque of 18 N m (13 ft-lbs.).
•
When using any racking manufacturer's frame mount bracket, follow the
manufacturer's recommended torque value and installation guidelines for frame
mounting the IQ8 Commercial Microinverter.
Step 4: Connect the microinverters
A. Connect the IQ8 Commercial Microinverter to the QD Cable connector. Listen for a click as
the connectors engage.
B. Ensure the QD connector is fully seated and locked on the microinverter AC Connector. You
can verify the connection using the green and red indicators on the QD Cable connector, as
shown in the image below.
