Engage Cable And Accessory Safety - enphase M250 Troubleshooting Manual

NOTE: The Enphase Microinverters has field-adjustable voltage and frequency trip points that may
need to be set, depending upon local requirements. Only an authorized installer with permission
and following the requirements of the local electrical authorities should make adjustments.
NOTE: The Enphase Microinverter works with single-phase or three-phase electrical service.

Engage Cable and Accessory Safety

DANGER: Risk of electric shock. The Engage Cable terminator cap must not be installed 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 damaged. 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. Sealing caps may not be reused.
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 by the grid. Sealing caps may not be reused.
WARNING: Use the terminator only once. If you open the terminator following installation, the
latching mechanism is destroyed. Do not reuse the terminator. Do not circumvent or manipulate the
latching mechanism.
CAUTION: When installing the Engage Cable, secure any loose cable to minimize tripping hazard.
NOTE: Check the labeling on the Engage Cable drop connectors to be sure that the cable matches
the electrical utility service at the site. Use 208 VAC Engage Cable at sites with three-phase
service, or use 240 VAC Engage Cable at sites with single-phase service.
NOTE: There are two release-holes in the drop connector 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 in. (12 cm) in
diameter.
NOTE: If you need to remove a sealing cap, you must use the Enphase disconnect tool or a
screwdriver. Sealing caps may not be reused.
NOTE: When installing the Engage Cable and accessories, 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 environments.

Do not allow the terminator to come into contact 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.
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.
