The following safety symbols and information indicate dangerous conditions and important safety instructions. This indicates a hazardous situation, which if not avoided, will result in death or serious injury. Risk of electrical shock. This indicates a situation where failure to follow instructions may result in burn injury. Before installing or using the Enphase Microinverter, read all instructions and cautionary markings in the technical description, on the Enphase Microinverter System, and on the photovoltaic PV equipment. Do not use Enphase equipment in a manner not specified by the manufacturer. Doing so may cause death or injury to persons, or damage to equipment. Risk of Electrical Shock. Be aware that installation of this equipment includes risk of electric shock. The Engage Cable terminator cap must not be installed while power is connected. The DC conductors of this photovoltaic system are ungrounded and may be energized. Always de-energize the AC branch circuit before servicing. Never disconnect the DC connectors under load. Disconnect DC connections first, then disconnect AC connections. The body of the Enphase Microinverter is the heat sink. To reduce risk of burns, use caution when working with microinverters. The M may be paired only with a cell PV module. This indicates a situation where failure to follow instructions may be a safety hazard or cause equipment malfunction. Use extreme caution and follow instructions carefully. This indicates information particularly important for optimal system operation. If the AC cable on the microinverter is damaged, do not install the unit. You must match the DC operating voltage range of the PV module with the allowable input voltage range of the Enphase Microinverter: The maximum open circuit voltage of the PV module must not exceed the specified maximum input voltage of the Enphase Microinverter: The M has field-adjustable voltage and frequency trip points that you may need to set, depending upon local requirements. Only an authorized installer with the permission and following requirements of the local electrical authorities should make adjustments. Only use electrical system components approved for wet locations. Only qualified personnel should troubleshoot, install, or replace Enphase Microinverters or the Engage Cable and Accessories. Make sure protective sealing caps have been installed on all unused AC connectors. Unused AC connectors are live when the system is energized by the grid. Sealing caps may not be reused. Ensure that all AC junction boxes are properly closed. The microinverter must be installed under the module, out of rain and sun. Do not mount the microinverter in a position that allows long-term exposure to direct sunlight or in a vertical orientation that allows water to collect in the DC connector recess. Do not install the microinverter black side up or vertically, with the DC connectors facing up. When installing the Engage Cable, secure any loose cable to minimize tripping hazard. Do not leave AC connectors on the Engage Cable uncovered for an extended period. If you do not plan to replace the microinverter immediately, you must cover any unused connector with a sealing cap. Do not exceed the maximum number of microinverters in an AC branch circuit as listed in the manual. You must protect each microinverter AC branch circuit with a 20A maximum breaker. 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 received prior approval from the electrical utility company. Do not attempt to repair the Enphase Microinverter; it contains no user-serviceable parts. If it fails, contact Enphase customer service to obtain an RMA return merchandise authorization number and start the replacement process. Tampering with or opening the Enphase Microinverter will void the warranty. Be aware that only qualified personnel must connect the Enphase Microinverter to the utility grid. If you need to remove a sealing cap, you must use the Enphase disconnect tool or a 3 Phillips screwdriver. When installing the Engage Cable and accessories, adhere to the following: Do not use the shipping cap to cover unused connectors. The shipping cap does not provide an adequate environmental seal. Enphase sealing caps are required for the system to be UL compliant and to protect Page 2

3 against moisture ingress. Completely install all microinverters and all system AC connections prior to installing the PV modules. The Engage Cable terminator cap is intended for one-time use only. If you open the terminator after initial installation, the latching mechanism is destroyed and the terminator cap cannot be used again. If the latching mechanism is defective, the terminator must not be used. The latching mechanism must not be circumvented or manipulated. When stripping the sheath from the Engage Cable, make sure that the conductors are not damaged. If the exposed wires are damaged, the system may not function properly. Check the labeling on the Engage Cable drop connectors to be sure that the cable matches the electrical utility service at the site. There are two release-holes in the drop connector on the cable. These are not for mounting but are used to disconnect the connector. Keep these release holes clear and accessible. Installation Map You can build the system map manually, or you can use the ArrayGun feature from the Enphase Installer Toolkit to easily build and configure a system. For more information, refer to http: To manually build the Installation Map: Protection against lightning and resulting voltage surge must be in accordance with local standards. 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 connectors do not conflict with the braces. Scan completed map and upload it to Enphase. COM 5 Installer information: The M meets the requirements of NEC Because the DC circuit is isolated and insulated from ground, the M does not require that you install a GEC between microinverters. Leave the Envoy running while you install the microinverters so that any required Envoy software upgrade completes. Lay out the cabling along the installed racking for the AC branch circuit. Install an appropriately rated, off-the-shelf junction box at a suitable location on the racking. See notes in Step Details on back. Engage Cable drop connector cable ties connects to drop connector AC junction box M DC connectors Check the drop connector labels to be sure that you have the right cable. Mark the approximate centers of each PV module on the PV racking. Mount the microinverter under the PV module, away from rain and sun. Torque the microinverter fasteners as follows. Do not over torque: For further information, refer to: Remove and discard the temporary shipping cap from the cable connector and connect the microinverter. Listen for two clicks as the connectors engage. Attach the cabling to the rack using cable clips or tie wraps. Cover any unused connectors with sealing caps. Dress any excess cabling in loops so that it does not contact the roof. Do not use shipping caps to cover unused connectors. Remove 60 mm 2. Check that all terminator parts are present. For more information, go to http: To manually build the map, peel the removable serial number label from each microinverter and affix it to the respective location on the map included with this guide. Slide the hex nut onto the cable. Insert the cable end all the way into the wire organizer up to the stop. Attach the terminated cable end to the PV racking with a cable clip or tie wrap. Mount the cell PV modules above the microinverters. It remains lit solid for two minutes, followed by six green blinks. After that, red blinks indicate that no grid is present. This is because the system is not yet energized. Page 3

To reduce the risk of electrical shock, and to ensure the safe installation and operation of the Enphase Microinverter, follow these in- structions. When powered up and connected for the first time, the Envoy may retrieve an automatic upgrade from Enphase. Because this upgrade may take up to 20 minutes, connect the Envoy first at the site connect to both AC power and the broadband router so that it performs the upgrade well before the solar module installation is complete. On the Engage Cable, connectors are spaced at intervals to allow for the widest PV modules compatible with Enphase Microinverters. If narrower PV modules are used, it may be necessary to account for excess cable by looping the cable at suitable intervals. Risk of electric shock. Be aware that installation of this equipment includes risk of electric shock. Only use electrical system components approved for wet locations. You may also earth the mounting rail and PV module to this conductor using a crimp connection. The AC output neutral is not bonded to earth inside the microinverter. When looping the Engage Cable, do not form loops smaller than 12 cm in diameter. Loose cables can become a tripping hazard. Dress the Engage Cable to minimise this potential. Connect The Microinverters AC connectors. Unused AC connectors are live when the system is energised by the electricity network. Sealing caps may not be reused. If you need to remove a sealing cap, you must use the Enphase disconnect tool or a screwdriver. Hold the cap with an Enphase disconnect tool, or insert a 2 Phillips screwdriver. Treat all connector contacts as though they are live. The Vac Engage Cable drop connector contains two live phases. Complete The Installation Map You can build the system map manually, by peeling the serial number labels from the microinverters and placing the labels on the installation map, or you can use the scanning tool feature from the Enphase Installer Toolkit to easily build and configure a system.
