Risk of Electrical Shock. Due to presence of exposed
conductors, DO NOT connect the Enphase Microinverters to
the utility grid or energize the AC circuit(s) until you have
completed all of the installation procedures as described in
the following sections.
Step 1 – Measure AC at Service Entrance Conductors
Measure AC line voltage at the service entrance conductors. Acceptable ranges
are shown in the following table.
240 Volt AC Split Phase 208 Volt AC 3 Phase
L1 to L2 211 to 264 Vac L1 to L2 to L3 183 to 229 Vac
L1, L2 to neutral 106 to 132 Vac L1, L2, L3 to neutral 106 to 132 Vac
Be sure the Engage Cable you are using matches the service
at the site. Use 208Vac cabling at sites with three-phase
208Vac service, or use 240Vac cabling at sites with 240Vac
service. Check the labeling on the cable drop connectors to
verify the cable type.
