Step 8: Connect the Microinverters
a. Remove and discard the temporary shipping caps 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 sealing cap engages. Ensure that
both latching mechanisms have engaged.
NOTES: Do not use the temporary shipping
cap to cover unused connectors. The
shipping cap does not provide an adequate
environmental seal. Enphase sealing caps are
required 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: Make sure protective sealing caps have been installed on all unused AC
connectors. Unused AC connectors are live when the system is energized by the utility
system. Sealing caps may not be reused.
NOTE: If you need to remove a sealing cap, you must use the Enphase disconnect tool
or a #3 Phillips screwdriver. See "Disconnect a Microinverter" on page 30. Sealing caps
may not be reused.
