Installation Guide

For full installation instructions for the Enphase IQ Series Microinverters,
read and follow all warnings and instructions in this guide and in the
Enphase IQ Series Microinverter Installation and Operation Manual at:
Check that you have Enphase Field Wireable Q Connectors as needed for
your installation. Both female and male connectors are sold in packs of ten:
Field Wireable Q connector (female): (Q-CONN-10F)
Field Wireable Q connector (male): (Q-CONN-10M)
Make sure you have the following recommended tools:
Diagonal cutter
Wire stripper
Crimp tool: Multi-Contact PV-CZM-18100, -19100, or -22100
Torque wrench
Enphase disconnect tool
When to Use Field Wireable Q Connectors
Use Enphase Field Wireable Q Connectors with Enphase Q Cable or eld
cable to:
Easily connect Q cables on the roof without complex wiring
Use male connectors to make connections from a Field Wireable
female connector
Use female connectors to make connections from any Q Cable
open connector
Make a jumper to connect with a remote part of the array: Use
female to female for cable-to-cable connections
Use a mated pair of connectors to splice two cut ends of cable
Safety Instructions
DANGER: Risk of electric shock. Do not use Enphase
equipment in a manner not specied by the manufacturer.
Doing so may cause death or injury to persons, or damage
to equipment.

of this equipment includes risk of electric shock. Do not use
without rst removing AC power from the Enphase System.
Disconnect the power coming from the photovoltaics
before servicing or installing.
DANGER: Risk of electric shock. Risk of re. Before making
any connections verify that the circuit breakers are in the off
position. Double check all wiring before applying power.
DANGER: Risk of electric shock. Risk of re. Only use
electrical system components approved for wet locations,
including but not limited to conduit ttings.
DANGER: Risk of electric shock. Risk of re. Only qualied
personnel should install, troubleshoot, or replace the
Enphase Field Wireable Q Connector.
DANGER: Risk of electric shock. Improper use of the Field
Wireable Q Connector or its components may result in a
shock, re or explosion. To reduce these risks, disconnect
all wiring before attempting any maintenance.
DANGER: Risk of electric shock. Risk of re. Ensure that all
AC and DC wiring is correct and that none of the AC wires
are pinched, shorted, or damaged.
DANGER: Risk of electric shock. Risk of re. Do not attempt
to repair or alter the Enphase Field Wireable Q Connector.
DANGER: Risk of electric shock. Risk of re. Make sure
the conductors are not damaged. If the exposed wires are
damaged, the system may not function properly.
WARNING: Risk of equipment damage. Enphase male and
female connectors must only be mated with the matching
male/female connector.
