WARNING: Risk of electric shock. Risk of fire.
+
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 fire. Do
+
not exceed the maximum number of microin-
verters in an AC branch circuit as listed in this
guide. You must protect each microinverter AC
branch circuit with a 20A maximum breaker.
WARNING: Do not connect Enphase Microin-
*
verters 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.
✓
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.
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 90°C. To
reduce risk of burns, use caution when working
with microinverters.
WARNING: Risk of electric shock. Risk of fire. If
+
the AC cable on the microinverter is damaged, do
not install the microinverter.
WARNING: Risk of electric shock. Risk of fire. 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.
WARNING: Risk of fire. The DC conductors of the
+
PV module must be labelled "PV Wire" or "PV Ca-
ble" when paired with the Enphase Microinverter.
WARNING: Risk of equipment damage. Install the
*
microinverter under the PV module to avoid direct
exposure to rain, UV, and other harmful weather
events. Do not mount the microinverter upside
down or in a vertical position that allows water to
collect in the DC connector recess as it may have
a harmful effect on the long term endurance of
the unit. Do not expose the AC or DC connectors
(on the Engage Cable connection, PV module,
or the microinverter) to harmful weather events
before the connectors are mated as it may result
in weather rated damage to the connection.
WARNING: Risk of equipment damage. The En-
*
phase Microinverter is not protected from damage
due to moisture trapped in cabling systems. Never
mate microinverters to cables that have been left
disconnected and exposed to wet conditions. This
voids the Enphase warranty.
WARNING: You must match the DC operating
*
voltage range of the PV module with the
allowable input voltage range of the Enphase
Microinverter.
WARNING: The maximum open circuit voltage
*
of the PV module must not exceed the specified
maximum input DC voltage of the Enphase
Microinverter.
Microinverter Safety, continued
WARNING: Risk of equipment damage. The
*
Enphase Microinverter functions only with a
standard, compatible PV module with appro-
priate fill-factor, voltage, and current ratings.
Unsupported devices include smart PV modules,
fuel cells, wind or water turbines, DC generators,
and non-Enphase batteries, etc. These devices
do not behave like standard PV modules, so
operation and compliance is not guaranteed.
These devices may also damage the Enphase
Microinverter by exceeding its electrical rating,
making the system potentially unsafe.
WARNING: Risk of electric shock. Risk of fire.
+
Only qualified personnel may connect the
Enphase Microinverter to the utility grid.
✓
NOTE: The Enphase Microinverter has field-adjust-
able voltage and frequency trip points that may
need to be set, depending upon local require-
ments. Only an authorized installer with the per-
mission and following requirements of the local
electrical authorities should make adjustments.
Engage Cable and Accessory Safety
DANGER: Risk of electric shock. Do not install
+
the Engage Cable terminator cap while power is
connected.
WARNING: Risk of electric shock. Risk of fire.
+
When stripping the sheath from the Engage
Cable, make sure the conductors are not dam-
aged. If the exposed wires are damaged, the
system may not function properly.
WARNING: Risk of electric shock. Risk of fire.
+
Do not leave AC connectors on the Engage
Cable uncovered for an extended period. If you
do not replace the microinverter immediately,
you must cover any unused connector with a
sealing cap. Do not reuse sealing caps.
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. Do not reuse sealing caps.
WARNING: Use the terminator only once. If
*
you open the terminator after installation,
the latching mechanism is destroyed. If the
latching mechanism is defective, do not use the
terminator. Do not circumvent or manipulate the
latching mechanism.
WARNING: When installing the Engage Cable,
*
secure any loose cable to minimize tripping
hazard

form loops smaller than 4.75 inches (12 cm) in
diameter.
✓
NOTE: If you need to remove a sealing cap, you
must use the Enphase disconnect tool or a #3
Phillips screwdriver. Do not reuse sealing caps.
✓
NOTE: When installing the Engage Cable and
accessories, adhere to the following:
• Do not expose the terminator cap or cable con-
nections to directed, pressurized liquid (water
jets, etc.).
• Do not expose the terminator cap or cable
connections to continuous immersion.
• Do not expose the terminator cap or cable
connections to continuous tension (e.g., tension
due to pulling or bending the cable near the
connection).

• Do not allow contamination or debris in the
connectors.
• Use the terminator cap and cable connections
only when all parts are present and intact.
• Do not install or use in potentially explosive
environments.
• Do not allow the terminator to come into con-
tact with open flame.
• Make sure that all terminator cap seals are
seated correctly in the wire organizer.
• Fit the terminator cap using only the prescribed
tools and in the prescribed manner.
• Use the terminator to seal the conductor end of
the Engage Cable; no other method is allowed.
