IQ 7 / IQ 7+ / IQ 7X / IQ 7A with EN4 Bulkhead Installation and Operation
You must match the DC operating voltage range of the PV module with the allowable input voltage
range of the Enphase Microinverter.
The Enphase 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.
The Enphase Microinverter functions only with a standard, compatible PV module with appropriate
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 are not guaranteed. These devices
may also damage the Enphase Microinverter by exceeding its electrical rating, making the system
potentially unsafe.
The Enphase Microinverter has field-adjustable voltage and frequency trip points that may need to
be set, depending upon local requirements. Only an authorized installer with the permission and
following requirements of the local electrical authorities should make adjustments.
Do not install the Enphase Q Cable terminator while power is connected.
When stripping the sheath from the Q Cable, make sure the conductors are not damaged. If the
exposed wires are damaged, the system may not function properly.
Do not leave AC connectors on the Q Cable uncovered for an extended period. You must cover any
unused connector with a sealing cap.
Make sure protective sealing caps have been installed on all unused AC connectors. Unused AC
connectors are live when the system is energized.
Use the terminator only once. If you open the terminator following 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.
When installing the Enphase Q Cable, secure any loose cable to minimize tripping hazard.
When looping the Enphase Q Cable, do not form loops smaller than 4.75" (12 cm) in diameter.
Provide support for the Enphase Q-Cable every 1.8m (6 feet).
If you need to remove a sealing cap, you must use the Enphase disconnect tool.
When installing the Enphase Q 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 or cable 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 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.
•
Fit the terminator cap using only the prescribed tools and in the prescribed manner.
•
Use the terminator to seal the conductor end of the Enphase Q Cable; no other method is
allowed.
