Disconnect A Microinverter - enphase M215-60-2LL-S23-IG Installation And Operation Manual

Disconnect a Microinverter

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 a microinverter 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. Cover the PV module with an opaque cover.
4. 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.
5. Disconnect the PV module DC wire connectors from the microinverter using the Enphase
disconnect tool.
6. If present, loosen the ground cleat screw and remove the grounding electrode conductor.
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.
