Field Wireable Q Connectors
You can use the male or female Field Wireable Q Connectors to extend the Q Cable (with connectors) or the
raw Q Cable (without connectors). Installers assemble the Field Wireable Q Connectors using a crimp tool
and the provided terminals.
Enphase recommends the Multi-Contact PV-CZM-18100, -19100, or -22100 crimp tools.
Each male or female Field Wireable Q Connector includes the corresponding male or female terminals, so
be sure to keep the terminals separate, as they are not interchangeable.
Note:
• Use only the provided terminals, and do NOT use the Field Wireable Q Connectors with other types
of terminals.
• Use the Field Wireable Q Connectors only with Enphase Q Cable, and do NOT use other types of
cables or conductors.

Field Wireable Q Connectors (Male)
IQ Microinverter, or a female Field Wireable Q Connector
Field Wireable Q Connectors (Female)
Q Cable connector or a male Field Wireable Q Connector
When the microinverters are located some distance from the roof top junction box, it may be most
economical to use raw Q Cable (without connectors) to run across an array or to run through raceway,
conduit or a chase to another array.
