Installation Procedure
Installing the Enphase Engage Cable and Accessories involves several key steps:
1. Measure AC at the Electricity Network Connection
2. Install the AC Branch Circuit Junction Box
3. Position the Enphase Engage Cable
4. Attach the Microinverters to the Mounting Rail
5. Dress the Enphase Engage Cable
6. Terminate the Unused End
7. Connect the Engage Cable to AC Junction Box(es)
8. Verification and Commissioning
Risk of Electrical Shock
Due to presence of exposed conductors, DO NOT connect the Enphase Micro-
inverters to the electricity network or energize the main AC circuit(s) until you
complete all of the installation procedures as described in the following sections.
Step 1 – Measure AC at the Electricity Network Connection
Measure AC line voltage at the electricity network connection to confirm that it is
within range. Acceptable ranges are shown in the following table.
Single-Phase Service
Three-Phase Service
L1 to neutral
L1 to L2 to L3
207 to 253 Vac
360 to 440 Vac
Be sure the Engage Cable you are using matches the electricity network connection
at the site. Use 5G2.5 Engage Cable at sites with three-phase (and neutral) service,
or use 3G2.5 Engage Cable at sites with single-phase service. Check the labelling on
the drop connectors to verify the voltage type.
Enphase Microinverters are designed to operate phase-to-neutral. When multiple
phases are present at sites with single-phase service, connect only one phase to each
Microinverter branch. Connecting multiple phases to a Microinverter branch circuit
will damage or destroy the Microinverters.
