Installing the Engage Cable
1
2
The Engage™ Cable is a continuous length of outdoor-rated cable with integrated connectors for microinverters preinstalled
at intervals to accommodate various PV module orientations. Enphase Microinverters plug directly into the cable connectors.
Read and follow all warnings and instructions in the
Engage Cable Installation Manual

Check the drop connector labels to
be sure that you have the right cable.
You must use 240 VAC cable for single phase
or 208 VAC cable for three-phase.
Position the Engage Cable
a.
Lay out the cabling along the installed racking for
the AC branch circuit.
b.
Install an appropriately rated, off-the-shelf junction
box at a suitable location on the racking.

Safety Instructions
DANGER
: Before installing or using the Enphase Microinverter,
read all instructions and cautionary markings in the technical
description and on the Enphase Microinverter System and the
photovoltaic (PV) equipment.
DANGER
: 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.
DANGER
: 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.
DANGER
: The Engage Cable terminator cap must not be
installed while power is connected.
WARNING
: Normally grounded conductors may be unground-
ed and energized when a ground fault is indicated.
WARNING
: Always de-energize the AC branch circuit before
servicing. Never disconnect the DC connectors under load. Dis-
connect DC connections first, then disconnect AC connections.
WARNING
: Only use electrical system components approved
for wet locations.
⚠
WARNING
: Only qualified personnel should troubleshoot,
install, or replace Enphase Microinverters or the Engage Cable
and Accessories.
⚠
WARNING
: 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.
⚠
WARNING
: Ensure that all AC and DC wiring is correct and
that none of the AC or DC wires is pinched or damaged. Ensure
that all AC junction boxes are properly closed.
⚠
WARNING
: 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 con-
nector with a sealing cap. Sealing caps may not be reused.
⚠
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 received prior approval
from the electrical utility company.
⚠
WARNING
: Be aware that only qualified personnel must con-
nect the Enphase Microinverter to the utility grid.
⚠
WARNING
: The Engage Cable terminator cap is intended for
one-time use only. If you open the terminator after initial instal-
lation, the latching mechanism is destroyed and the terminator
cap cannot be used again. If the latching mechanism is defec-
tive, the terminator must not be used. The latching mechanism
must not be circumvented or manipulated.
⚠
WARNING
: 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.
⚠
WARNING
: Perform all electrical installations in accordance with
all applicable local electrical codes and the National Electrical
Code (NEC), ANSI/NFPA 70.
✓
NOTE
: Check the labeling on the Engage Cable drop con-
nectors to be sure that the cable matches the electrical utility
service at the site. Use 208 VAC (208 VAC three-phase) Engage
Cable at sites with three-phase 208 VAC service, or use 240
VAC Engage Cable at sites with 240 VAC single-phase service.
✓
NOTE
: When installing the Engage Cable, secure any loose
cable to minimize tripping hazard.
✓
NOTE
: There are two release-holes in the drop connector on
the Engage Cable. These are not for mounting but are used to
disconnect the connector. Keep these release holes clear and
accessible.
✓
NOTE
: When installing the Engage Cable and accessories,
adhere to the following:
• Do not expose the connection to directed, pressurized liquid
(water jets, etc.).
• Do not expose the connection to continuous immersion.
• Do not expose the AC connector to continuous tension (e.g.,
tension due to pulling or bending the cable near the connec-
tion).
• Use only the connectors and cables provided.
• Do not allow contamination or debris in the connectors.
• Use the cable and connectors only when all parts are
present and intact.
• Fit the connections using only the prescribed tools.
• Use the terminator to seal the conductor end of the Engage
Cable; no other method is allowed.
✓
NOTE
: Protection against lightning and resulting voltage surge
must be in accordance with local standards.
✓
NOTE
: If you need to remove a sealing cap, you must use the
Enphase disconnect tool or a #3 Phillips screwdriver. Sealing
caps may not be reused.
