Select wire that is Code type, NRTL certified, and rated for voltage and temperature for the specific
application. Mechanically protect the wires in a Code type, NRTL certified conduit or raceway. Use NRTL
certified connectors for splices and insulated splices from one another and from the raceway, conduit, or
junction box, if metallic.
Buried wires must be NRTL certified for direct burial and follow the Code for installation. Do not bury splices
unless in a NRTL certified junction box rated for the application, and use an NRTL certified moisture resistant
connection method.

The update may take up to 20 minutes. The Envoy reboots several times during the update and the LEDs
light up in varied sequences until the update is complete.
Once the update is finished and the PV system is installed, the Envoy is ready for Installation Part 2.
All four LEDs flash amber during boot up (approximately 3 minutes). When boot up is complete, the Device
Communications LED flashes amber indicating that microinverters are not yet detected.
