B. Mark the approximate centres of each PV module on the PV racking.
C. Lay out the cabling along the installed racking for the AC branch circuit.
D. Cut each segment of cable to meet your planned needs.
WARNING: When transitioning between rows, secure the cable to the rail to prevent cable damage
or connector damage. Do not count on the connector to withstand tension.

Step 2: Position the junction box

A. Verify that the AC voltage at the site is within range.

B. Install a junction box at a suitable location on the racking.
C. Provide an AC connection from the junction box back to the electricity network using equipment
and practices as required by local jurisdictions.

Step 3: Mount the microinverters

A. If the Enphase DC bulkhead connectors are not already attached to the microinverters, attach them
now. Make sure they are fully seated.
B. Mount the microinverter bracket side up (as shown) and under the PV module, away from rain and
sun. Allow a minimum of 1.9 cm between the roof and the microinverter. Also, allow 1.3 cm between
the back of the PV module and the top of the microinverter.
WARNING: Install the microinverter under the PV module to avoid direct exposure to rain, UV, and
other harmful weather events. Do not mount the microinverter upside down.
WARNING: IQ7A installs are not recommended with bi-facial modules, and use of such may impact
the limited warranty.
C. Torque the microinverter fasteners as follows. Do not over-torque.
• 6 mm mounting hardware: 5 N m
• 8 mm mounting hardware: 9 N m
• When using UL 2703 mounting hardware, use the manufacturer's recommended torque value
