enphase M215 Instructions Manual page 2

⚠
WARNING: 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: The microinverter must be installed under
the module, out of rain and sun. Do not mount the micro-
inverter 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 con-
nectors facing up.
⚠
WARNING: When installing the Engage Cable, secure
any loose cable to minimize tripping hazard.
⚠
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 connector with a sealing cap. Sealing
caps may not be reused.
⚠
WARNING: Do not exceed the maximum number of mi-
croinverters 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 Microinverters to
the grid or energize the AC circuit(s) until you have com-
pleted all of the installation procedures and have received
prior approval from the electrical utility company.
⚠
WARNING: Do not attempt to repair the Enphase Micro-
inverter; 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: Be aware that only qualified personnel may
connect the Enphase Microinverter to the utility grid.
⚠
WARNING: Use the terminator only once. If you open
the terminator following installation, the latching mecha-
nism is destroyed. Do not reuse the terminator. If the
latching mechanism is defective, do not use the ter-
minator. Do not circumvent or manipulate the latching
mechanism.
⚠
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 accor-
dance with all applicable local electrical codes and the
National Electrical Code (NEC), ANSI/NFPA 70.
✓
NOTE: To ensure optimal reliability and to meet war-
ranty requirements, the Enphase Microinverter must be
installed according to the instructions in this guide.
✓
NOTE: The AC and DC connectors on the cabling are
rated as a disconnect only when used with an Enphase
Microinverter.
✓
NOTE: Check the labeling on the Engage Cable drop
connectors to be sure that the cable matches the electri-
cal 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: There are two release-holes in the drop con-
nector on the cable. These are not for mounting but are
used to disconnect the connector. Keep these release
holes clear and accessible.
✓
NOTE: When looping the Engage Cable, do not form
loops smaller than 4.75 inches (12 cm) in diameter.
✓
NOTE: Protection against lightning and resulting voltage
surge must be in accordance with local standards.
✓
NOTE: Many PV modules have a central stiffening brace.
In these cases, do not position the connector and micro-
inverter at the exact center of the PV module. Instead,
position the drop connectors so that the connectors do
not conflict with the braces.
✓
NOTE: If you need to remove a sealing cap, you must
use the Enphase disconnect tool or a #3 Phillips screw-
driver. Sealing caps may not be reused.
✓
NOTE: The M215 works with 240 VAC single-phase util-
ity service or with 208 VAC three-phase utility service
✓
NOTE: When installing the Engage Cable and accesso-
ries, adhere to the following:
• Do not expose the terminator cap or cable connections
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).
• Use only the connectors and cables provided.
• 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 environ-
ments.
• Do not allow the terminator to come into contact with
open flame.
• Make sure that all terminator cap seals are seated cor-
rectly 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.
✓
NOTE: 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 to protect against moisture ingress.
✓
NOTE: Completely install all microinverters and all sys-
tem AC connections prior to installing the PV modules.
