B. Enphase AC connectors are tool-removable only. To disconnect the microinverter from the
Enphase Q Cable, insert the disconnect tool and remove the connector.
C. Cover the PV module with an opaque cover.

module and the microinverter. If current is still flowing, check that you have completed steps

first and tend to drift with time.
E. Disconnect the PV module DC wire connectors from the microinverter using the Enphase
disconnect tool.
F. If present, loosen and/or remove any bonding hardware.
G. Remove the microinverter from the PV racking.
WARNING: Risk of electric shock. Risk of fire. Do not leave any connectors on the PV
