Important Safety Information Read this First To reduce the risk of electrical shock, and to ensure the safe installation and operation of the Enphase System, the following safety indications appear throughout this document. Indicates a hazardous situation, which if not avoided, will result in death or serious injury.
In some areas, the statistical frequency of lightning strikes near a PV installation is high enough that lightning protection must be installed as part of an Enphase system. In some areas, a surge protection device might be mandatory following a risk analysis, according to local regulation, BS 7671, or NF C 15- 100 (art.
The voltage types are either single-phase or three-phase. All Engage Cable connectors bear labels indicating the voltage designation. Single-phase (3G2.5) Engage Cable includes three conductors. Three-phase (5G2.5) Engage Cable includes five conductors. Because Enphase microinverters output onto one phase, the 5G2.5 Engage Cable balances the phases by rotating conductor use from one microinverter to the next as shown in the following diagram.
Engage Cable and Accessories Installation Planning for Engage Cable Lengths and Type The Enphase Engage Cable and Accessories are flexible enough to adapt to almost any solar design. To determine the length and type that you need, take into account the following considerations: ...
Engage Cable and Accessories Installation Installing Enphase Engage Cable and Accessories Follow the instructions in this section to install the Enphase Engage Cable and Accessories. For information on microinverter installation, refer to the M215 Installation and Operation Manual at http://www.enphase.com/support/downloads.
Engage Cable and Accessories Installation 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.
Engage Cable to minimize this potential. NOTE: Do NOT exceed the maximum number of microinverters in an AC branch circuit as listed in the Enphase Microinverter Installation manual, and protect each microinverter AC branch circuit with a 20 A maximum breaker (or in accordance with local installation code).
Module widths vary by manufacturer. On the Engage Cable, connectors are spaced at intervals to allow for the widest PV modules compatible with Enphase Microinverters. If narrower modules are used, it may be necessary to account for excess cable by adding a loop of cable at suitable intervals.
These holes are to be used only for disconnecting. Keep these release holes clear and accessible. a. Attach the Enphase Cable to the rail using tie wraps. b. Dress any excess in loops so that Engage Cable does not contact the roof.
NOTE: If you need to remove a sealing cap, you must use the Enphase disconnect tool. See “Disconnecting a Microinverter from the Engage Cable” on page 19 for more information on disconnection.
Slide the hex nut onto the Engage Cable. e. Insert the Engage Cable end all the way into the wire organizer (up to the stop). Copyright 2012 Enphase Energy 141-00016 Rev 03...

Insert a #2 Philips screwdriver into the slot on the cap to hold it in place. (Alternatively you can hold the cap firmly in place using the Enphase disconnect tool). k. Use a 22mm (7/8 inch) spanner and tighten the nut until the latching mechanism has been screwed all the way to the base.
Risk of Electrical Shock. Be aware that installation of this equipment includes risk of electric shock. Do not install the AC junction box without first removing AC power from the Enphase System. Never open, remove or replace the terminator while it is connected to the power supply.
Ensure that all unused connectors are capped. d. Ensure that all connectors are properly seated. e. Install the microinverters and commission the system as instructed by the Enphase Microinverter installation and operation manual and in accordance with all local and national requirements.
If you do not plan to replace the microinverter immediately, you must cover any unused connector with a sealing cap. Listen for two clicks as the cap engages. Sealing caps may not be reused. Copyright 2012 Enphase Energy 141-00016 Rev 03...
