Step 8: Complete The Installation Of The Junction Box; Step 9: Connect The Pv Modules - enphase IQ8 Series Installation And Operation Manual

Single-phase IQ Cable
E. Secure the terminated cable end to the PV
racking with a cable clip or tie wrap so that the
cable and IQ Terminator are not in contact with
the roof surface.
NOTE: Turn only the hex nut to prevent conductors from twisting out of the separator.
WARNING: The IQ Terminator cannot be re-used. If you unscrew the nut, you must discard the
IQ Terminator as the IP rating of the terminator now has been compromised.

Step 8: Complete the installation of the junction box

A. Connect the IQ Cable to the junction box.
B. Refer to the electrical diagrams on page 33 for more information. Conductor colours are listed as
follows:
NOTE: The multi-phase IQ Cable internally rotates L1, L2, and L3 to provide balanced 400 VAC
(multi-phase), thus alternating phases between microinverters.
NOTE: Minimize the number of unused IQ Cable connectors with multi-phase systems. When cable
connectors are left unused on a multi-phase system, it creates a phase imbalance on the branch
circuit. If multiple cable connectors are skipped over multiple branch circuits, the imbalance will
multiply. This could impact system performance due to phase imbalance requirements.

Step 9: Connect the PV modules

WARNING: Electric shock hazard. The DC conductors of this photovoltaic system are not earthed
and will be energized when PV modules are exposed to
sunlight.
A. Connect the DC leads of each PV module to the DC input
connectors of the corresponding microinverter. Listen for a
click as connectors engage.
B. Check the LED on the connector side of the microinverter. The
LED flashes green six times when DC power is applied.
C. Mount the PV modules above the microinverters.
