Disconnecting a Microinverter from the Engage
Cable
To ensure the microinverter is not disconnected from the PV modules under load,
adhere to the following disconnection steps in the order shown:
1. Disconnect the microinverter AC connector from the Engage Cable.
2. Cover the module with an opaque cover.
3. Using a DC current probe, verify there is no current flowing in the DC
wires between the PV module and the microinverter.
Care should be taken when measuring DC currents due to the
fact that most clamp-on meters must be zeroed first and tend
to drift with time.
4. Disconnect the PV module DC wire connectors from the microinverter.
5. Remove the microinverter from the PV array
racking.
6. The microinverter connectors are tool-
removable only. The installation kit includes
a disconnect tool with two prongs. To
disconnect a microinverter from the cabling
system, insert these two prongs into the two
holes in the cable connector. Squeeze the
sides of the disconnect tool to engage with
the connector. Rock the connector back and forth while pulling gently
to disengage.
7. If the disconnect tool is not available, a #2 Phillips screwdriver can be
used in its place. Insert the screwdriver into one hole, rock that side of
the drop connector out, then insert the screwdriver into the other hole
and pull the connector out entirely.
Risk of Electrical Shock . Do not leave the drop connector
uncovered for an extended period. If you do not plan to
replace the microinverter immediately, you must cover any
unused connector with a watertight sealing cap. Listen for two
clicks as the connectors engage.
