Terminate the Unused End of the Cable
A ) Remove 13 mm (1/2") of the cable sheath from
the conductors. Use the terminator loop to measure.
Terminator Body
B ) Slide the hex nut onto the cable. There is a grommet inside of the
terminator body that should remain in place.
C ) Insert the cable into the terminator body so that each of the two
wires land on opposite sides of the internal separator.
D ) Insert a screwdriver into the slot on the top of the terminator to
hold it in place, and tighten nut with 27 mm open-end wrench or
channel lock pliers until fully tightened.
Hold the terminator body stationary with the screwdriver and turn
only the hex nut to prevent the conductors from twisting out of the
separator.
F ) Manage the terminated cable end to the PV racking with a cable
clip or tie wrap so that the cable and terminator do not touch the
roof.
WARNING: Never unscrew the hex nut. Unscrewing
the hex nut destroys the locking feature, and you must
replace the terminator.

Connect to an Enphase Q Aggregator or Junction Box
A) Connect the Enphase Q Cable into the Enphase Q Aggregator or
junction box.
B) Use the ground lug on the Q Aggregator for module, rack, and
balance of system grounding, if needed.
The Q Cable uses the following wiring color code:

DANGER! Electric shock hazard. The DC
conductors of this PV 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.
B ) Check the LED on the connector side
of the microinverter. The LED flashes
six times when DC power is applied.
C) Mount the PV modules above the
microinverters.

Energize the System
A ) If applicable, turn ON the AC disconnect or circuit breaker for the
branch circuit.
B ) Turn ON the main utility-grid AC circuit breaker. Your system will
start producing power after a five-minute wait time.
C ) Check the LED on the connector side of the microinverter:
