11 Energize the System <br />a. Turn ON the AC disconnect or circuit breaker <br />for the branch circuit, <br />b. Turn ON the main utility-grid AC circuit breaker. <br />Your system will start producing power after a <br />five-minute wait time. <br />--. status LEDt ., <br />One minute after DC power is ap- <br />plied, the status LED on the under- <br />side of each M215 will blink green six <br />times to indicate normal start up. <br />Next Step <br />Refer to the Envoy Communications Gateway Quick <br />/nsta# Guide for information on Envoy® installation <br />and Eniighten® access. <br />Step Details <br />0 <br />NOTE: Verify that AC voltage at the site Ts within range: <br />240 Volt AC Split Phase 208 Volt AC Three Phase <br />Ll to L.2 211 to 264 VAC Ll to L.2 to L3 183 to 229 VAC <br />Lli L2, to N 106 to 132 VAC Ll. L.2, L3 to N 106 to 132 VAC <br />WARNING: Only use electrical system components approved <br />for wet locations. <br />WARNING: Do NOT exceed the maximum number of micro- <br />inverters n an AC branch circuit as listed in the table below. <br />Each branch circuit must be protected by a dedicated circuit <br />breaker ot 20 A or less. <br />Service type Max M215s per branch <br />240 VAC split phase 1 7 <br />208 VAC three phase 25 <br />WARNING: Size the AC wire gauge to account for voltage drop <br />for both the branch circuit and all upstream conductors leading <br />back to the PCC. See Circuit Calculations for /0215 at http:// <br />www.enphase.com/support. <br />0 <br />WARNING: Allow a minimum of 1.9 cm (0.75") between the <br />roof and the microinverter. Also allow 1.3 cm CO.50") between the <br />back ot the PV module and the top of the microinverter. <br />NOTE: Torque the microinverter fasteners to the values shown. <br />Do not over torque: <br />• 6 mm (1/4") mounting hardware -5 Nm (45-50 In-lbs) <br />• 8 mm (5/161 mounting hardware -9 Nm (80-85 in-lbs) <br />Using a power screwdriver is not recommended due to the risk <br />of thread galling. <br />0 <br />NOTE: The AC output neutral is not bonded to ground inside <br />the microinverter, <br />NOTE: The M215 grounding cleat can accommodate a 6 to 8 <br />AWG conductor. Torque the 10/32 grounding cleat screw to <br />2 N m (20-25 in-lbs). Do not over torque. Using a power screw- <br />driver is not recommended due to the risk of thread galling. <br />0 <br />WARNING: Install scaling caps on all unused AC connectors <br />as these become live when the system iq <br />energized by the utility The IP67-rated T disconnectsealing caps are required for tool <br />protection against moisture ingress. <br />NOTE: To remove a scaling cap, you <br />must use the Enphase disconnect tool <br />a #2 Philiips screwdriver. <br />0 <br />Enphase Energy, Inc. <br />1420 N.
