Step 8: Complete The Installation Of The Junction Box; Step 9: Connect The Pv Modules - enphase IQ7 Installation And Operation Manual

WARNING: The terminator cannot be re-used. If you unscrew the nut, you must discard the
terminator.

Step 8: Complete the installation of the junction box

A. Connect the IQ Cable to the junction box.
B. For more information, refer to the
code:
NOTE: The IQ Cable internally rotates L1, L2, and L3 to provide balanced 400 VAC (three-phase),
thus alternating phases between microinverters.
NOTE: Minimise the number of unused IQ Cable connectors with three-phase systems. When cable
connectors are left unused on a three-phase system, it creates a phase imbalance on the branch
circuit. If multiple cable connectors are skipped over multiple branch circuits, the imbalance can
multiply.

Step 9: Connect the PV modules

WARNING: Electrical shock hazard. The DC conductors of this photovoltaic system are
ungrounded and may be energized.
A. Connect the DC leads of each PV module to the DC input connectors of the corresponding
microinverter.
