WARNING: Risk of electric shock. Risk of fire. Always de-energise the AC branch circuit before servicing.
Never disconnect the DC connectors under load.
WARNING: DO NOT connect Enphase Microinverters to the electricity network or energise the AC circuit(s)
until you have completed all of the installation procedures as described in the following sections.
NOTE: Some Enphase Microinverters will not begin exporting power until the Envoy Communications Gateway
is installed and has detected all of the microinverters at the site. In addition, the grid profile must be configured
and the Envoy must have propagated these settings to the microinverters. For instructions on this procedure,
refer to the Envoy Installation and Operation Manual at http://www.enphase.com/support.
