Disconnect A Microinverter - enphase IQ 7 Installation And Operation Manual

Disconnect a Microinverter

If problems remain after following the troubleshooting steps listed previously, contact Customer
Support at https://enphase.com/en-us/support/global-contact.
If Enphase authorizes a replacement, follow the steps below. To ensure the microinverter is not
disconnected from the PV modules under load, follow the disconnection steps in the order shown:
A. De-energize the AC branch circuit breaker.
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.
D. Using a clamp-on meter, verify there is no current flowing in the DC wires between the
PV module and the microinverter. If current is still flowing, check that you have completed
steps one and two above.
NOTE: Take care when measuring DC current as most clamp-on meters must be
zeroed 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 system disconnected for an extended period. If you do not plan to replace the
microinverter immediately, you must cover any unused connector with a sealing cap.
