Page 7: The Enphase Engage Cable And Accessories
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 NFC 15-100 (art. -
Page 8: Selecting Cable Type
Selecting Cable Type Enphase Engage Cable is available in two different voltage types and two connector spacing options. Depending upon installer needs, the cable is also available in different lengths. The cable is installed by simply rolling out the desired length of cable and cutting it to size. -

208VAC applications. Three-phase 208VAC cabling includes five conductors, and is used for most commercial installations. Because Enphase microinverters output onto two phases, three phase cabling balances the phases by rotating conductor use from one microinverter to the next as shown in the following diagram. -

8. Verification and Commissioning 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. -
Page 13: Step 2 - Install The Ac Branch Circuit Junction Box
PV racking system (typically at the end of a row of modules). c. Provide an AC connection from the junction box back to the utility interconnection, using equipment and practice as required by the NEC and local jurisdictions. Page 13 Copyright Enphase Energy Inc. 2011 141-00013 Rev 03b... -
Page 14: Step 3 - Position The Enphase Engage Cable
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. -
Page 15: Step 5 - Dress The Engage Cable
Place tie wraps or clips on either side of the drop connector. Use one or two additional clips, tie wraps, or other support scheme to secure the cable between connectors. d. Remove the temporary shipping cap from the Engage Cable. Page 15 Copyright Enphase Energy Inc. 2011 141-00013 Rev 03b... - Page 16 IP67 indicates that this connector protects against all dust particles and immersion in liquid. If you need to remove a watertight sealing cap, you must use the Enphase disconnect tool or a #2 Phillips screwdriver. Page 16 Copyright Enphase Energy Inc. 2011...

Page 17: Step 6 - Terminate The Unused End Of The Engage Cable
The wire organizer must be complete, as shown. Risk of Electrical Shock. The terminator cap must not be installed while power is connected. Page 17 Copyright Enphase Energy Inc. 2011 141-00013 Rev 03b... - Page 18 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 hand tool). k. Use a 24mm (7/8 inch) wrench and tighten the nut until the latching mechanism has been screwed all the way to the base.

Page 19: Replacing Or Removing The Terminator
Connect the Engage Cable into additional junction boxes as needed to transition to conduit between smaller sub- arrays. Remember to adhere to branch limits for the microinverters being used. Page 19 Copyright Enphase Energy Inc. 2011 141-00013 Rev 03b... - Page 20 Refer to the wiring diagrams located in the Appendix of this manual for more information. The Engage Cable uses a different wiring scheme than used with other Enphase Microinverters. Be aware of the difference in wire color code. The 12 AWG conductors are identified as follows: L1 is sheathed in Black, L2 is sheathed in red, L3 is sheathed in blue (208 Vac only), Neutral is sheathed in white, and Ground is sheathed in green.

Page 21: Step 8 - Verification And Commissioning
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. Page 21 Copyright Enphase Energy Inc. 2011... -
Page 22: Disconnecting A Microinverter From The Engage Cable
If you do not plan to replace the microinverter immediately, you must cover any unused connector with a watertight sealing cap. Listen for two clicks as the connectors engage. Page 22 Copyright Enphase Energy Inc. 2011 141-00013 Rev 03b... -
