IQ7 Series Microinverters safety instructions
General safety
DANGER: Risk
of electric
shock. Risk of
fire.
Only use electrical system components approved for wet locations.
Only competent personnel should install, troubleshoot, or replace Enphase
microinverters or IQ Cable and accessories.
Ensure that all AC and DC wiring is correct and that none of the AC or DC cables are
pinched, shorted, or damaged. Ensure that all AC junction boxes are properly closed.
Do not exceed the maximum number of microinverters in an AC branch circuit as listed
in the manual. You must protect each microinverter AC branch circuit with a 20 A
maximum breaker or fuse as appropriate.
DANGER: Risk
of electric
shock.
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.
Be aware that installation of this equipment includes the risk of electric shock.
The DC conductors of this photovoltaic system are ungrounded and may be
energized.
Always de-energize the AC branch circuit before servicing. Never disconnect the DC
or AC connectors under load.
WARNING:
Before installing or using the Enphase microinverter, read all instructions and
cautionary markings in the technical description, on the Enphase equipment, and on
the photovoltaic (PV) equipment.
Do not connect Enphase microinverters to the grid or energize the AC circuit(s) until
you have completed all the installation procedures and have received approval from
the electrical network operator.
When the PV array is exposed to light, DC voltage is supplied to the power conversion
equipment (PCE).
Risk of equipment damage. Enphase male and female connectors must only be mated
with the identical type and brand of male/female connector.
NOTE:
To ensure optimal reliability and to meet warranty requirements, install the Enphase
equipment according to the instructions in this manual.
The AC and DC connectors on the cabling are rated as a disconnect only when used
with an Enphase microinverter.
Protection against lightning and resulting voltage surge must be in accordance with
local electrical codes and standards.
Perform all electrical installations in accordance with all applicable local electrical
codes and standards.
Microinverter safety
WARNING: Risk of
skin burn.
The chassis of the Enphase microinverter is the heat sink. Under normal operating
conditions, the temperature could be 20°C above ambient temperature, but under
extreme conditions, the microinverter can reach a temperature of 90°C. To reduce the
risk of burns, use caution when working with microinverters.
DANGER: Risk of
fire.
The DC conductors of the PV module must be labeled “PV Wire” or “PV Cable” when
paired with the Enphase microinverter.
