M215 Installation and Operation
2013 Enphase Energy Inc. 141-00012 Rev 05
Disconnect a Microinverter from the PV Module
If problems remain after following the troubleshooting steps listed previously, contact Enphase at
support@enphaseenergy.com. If Enphase authorizes a replacement, follow the steps below. To ensure
the microinverter is not disconnected from the PV modules under load, adhere to the following
disconnection steps in the order shown:
1. De-energize the AC branch circuit breaker.
2. Disconnect the microinverter from the Engage Cable as follows:
Enphase AC connectors are tool-removable only. To disconnect an M215 from the Engage
Cable, insert the two large prongs of the disconnect tool (see illustration) into the two holes in
the drop connector. Rock the connector back and forth while pulling gently to disengage.
If the disconnect tool is not available, insert a #3 Phillips screwdriver into one hole, and rock
that side of the drop connector out. Then, insert the screwdriver into the other hole and pull
the connector out entirely.
3. Loosen the ground cleat screw and remove the grounding electrode conductor.
4. Cover the PV module with an opaque cover.
5. Using a clamp on meter, verify there is no current flowing in the DC wires between the PV
module and the microinverter.
NOTE: Take care when measuring DC current, as most clamp-on meters must be zeroed
first and tend to drift with time.
6. Disconnect the PV module DC wire connectors from the microinverter using the Enphase
disconnect tool.
7. Remove the microinverter from the PV racking.
WARNING: Do not leave AC connectors on the Engage Cable uncovered for an
extended period. If you do not plan to replace the microinverter immediately, you must
cover any unused connector with a sealing cap. Sealing caps may not be reused.
