WARNING: Hot surface.

DANGER: Refer to safety instructions.

DANGER: Risk of electric shock.

Safety Instructions

General Safety

DANGER: Before installing or using the Enphase Micro-

inverter, read all instructions and cautionary markings in

the technical description, on the Enphase Microinverter

System, and on the photovoltaic (PV) equipment.

DANGER: Risk of electric shock. Do not use Enphase

equipment in a manner not specied by the manufac-

turer. Doing so may cause death or injury to persons, or

damage to equipment.

DANGER: Risk of electric shock. Be aware that installa-

tion of this equipment includes risk of electric shock. Do

not install the AC junction box without rst removing AC

power from the Enphase System.

DANGER: Risk of electric shock. The DC conductors

of this photovoltaic system are ungrounded and may be

energized.

WARNING: Risk of electric shock. Always de-energize

the AC branch circuit before servicing. Never disconnect

the DC connectors under load.

WARNING: Risk of electric shock. Risk of re. Only use

electrical system components approved for wet locations.

WARNING: Risk of electric shock. Risk of re. Only

qualied personnel should troubleshoot, install, or re-

place Enphase Microinverters or the Engage Cable and

Accessories.

WARNING: Risk of electric shock. Risk of re. Ensure

that all AC and DC wiring is correct and that none of the

AC or DC wires are pinched or damaged. Ensure that all

AC junction boxes are properly closed.

WARNING: Risk of electric shock. Risk of re. Do not

exceed the maximum number of microinverters in an AC

branch circuit as listed in this guide. You must protect

each microinverter AC branch circuit with a 20A maxi-

mum breaker.

WARNING: Do not connect Enphase Microinverters

to the grid or energize the AC circuit(s) until you have

completed all of the installation procedures and have re-

ceived prior approval from the electrical utility company.

✓

NOTE: To ensure optimal reliability and to meet warranty

requirements, install the Enphase Microinverters and

Engage Cable according to the instructions in this guide.

✓

NOTE: Perform all electrical installations in accordance

with all applicable local electrical codes and the National

Electrical Code (NEC), ANSI/NFPA 70.

✓

NOTE: The AC and DC connectors on the cabling are

rated as a disconnect only when used with an Enphase

Microinverter.

✓

NOTE: Protection against lightning and resulting voltage

surge must be in accordance with local standards.

✓

NOTE: Many PV modules have a central stiffening

brace. In these cases, do not position the connector

and microinverter at the exact center of the PV module.

Instead, position the drop connectors so that the con-

nectors do not conict with the braces.

✓

NOTE: Completely install all microinverters and all sys-

tem AC connections prior to installing the PV modules.

follow instructions may be a safety hazard or cause

equipment malfunction. Use extreme caution and follow

instructions carefully.

WARNING! This indicates a situation where failure to

follow instructions may result in burn injury.

✓

NOTE: This indicates information particularly important

for optimal system operation. Follow instructions care-

fully.

Safety Instructions, continued WARNING: Risk of electric shock. Risk of fire. Make sure protective sealing caps have been installed on all unused AC connectors. Unused AC connectors are live when the system is energized. Sealing caps may not be reused. Microinverter Safety WARNING: Risk of skin burn. The body of the Enphase Microinverter is the heat sink. Under normal operating conditions, the temperature is 20°C above ambient, but under extreme conditions the microinverter can reach a temperature of 90°C.

® Q U I C K I N S TA L L G U I D E Installing the Enphase S-Series Microinverters and Engage Cable The Enphase S-Series Microinverter (S280-60-LL and S230-60-LL) meets the requirements of NEC 690.35. Enphase Microinverters do not require that you install a GEC between microinverters because the DC circuit is isolated and insulated from ground. Ground fault protection (GFP) is integrated into the microinverter.

1 2 Position the Enphase Engage™ Cable a. Plan the cable length to allow drop connectors on the Engage Cable align to with each PV module. Allow extra length for slack, cable turns and any obstructions. b. Cut a length of Engage Cable to meet your planned needs. c. Lay out the cabling along the installed racking for the AC branch circuit. c. Torque the microinverter fasteners as follows.

Q U I C K I N S TA L L G U I D E 6 Connect the Microinverters a. Remove and discard the temporary shipping cap from the cable connector and connect the microinverter. Listen for two clicks as the connectors engage. 7 Terminate the Unused End of the Cable a. Remove 60 mm (2.5”) of the cable sheath from the conductors. b. Check that all terminator parts are present. hex nut b. Cover any unused connectors with Enphase Sealing Caps. Listen for two clicks as the connectors engage.

8 Connect the Cable to the AC Junction Box 10 Connect the Engage Cable into the AC branch circuit junction box. See notes in Step Details. 11 Energize the System a. If applicable, turn ON the AC disconnect or circuit breaker for the branch circuit. b. Turn ON the main utility-grid AC circuit breaker. Your system will start producing power after a five-minute wait time.
