Enphase Microinverter Installation and Operation

Step 7: Connect the Microinverters

a. Remove and discard the temporary shipping cap from
the Engage Cable and connect the microinverter. There
are two latching mechanisms within the connectors.
Listen for two clicks as the connectors engage. Ensure
that both latching mechanisms have engaged.
b. Repeat for all microinverters in the AC branch circuit.
c. Cover any unused connector with a sealing cap. Listen
for two clicks as the connectors engage. Ensure
that both latching mechanisms have engaged.
NOTE: Do not use the shipping cap to cover unused
connectors. The shipping cap does not provide an
adequate environmental seal. Enphase sealing caps are
required for the system to compliant to regulation and to
protect against moisture ingress.
Enphase sealing caps are IP67 rated. Within the term
"IP67", "IP" indicates an Ingress Protection (IP) rating against dust and liquids. This specific rating of IP67
indicates that this connector protects against all dust particles and immersion in liquid.
WARNING: Risk of electric shock. Risk of fire. Make sure protective sealing caps have been installed on all
unused AC connectors. Unused AC connectors are live when the system is energised by the electricity
network. Sealing caps may not be reused.
NOTE: If you need to remove a sealing cap, you must use the Enphase disconnect tool or a screwdriver. See
"Disconnect a Microinverter" on page 28. Sealing caps may not be reused.
