operation. Take measures to prevent personal injury or property loss caused
by accidental contact by non-professionals or other reasons during device
operation.
● Do not install the inverter in areas containing ammable materials (such as
sulfur, phosphorus, liqueed petroleum gas, marsh gas, our, and cotton) to
avoid personal injury or property loss caused by re or other reasons.
● Do not install the inverter in areas containing explosives (such as blasting
agents, display shells, reworks, and recrackers) to avoid personal injury or
property loss caused by explosion or other reasons.
● Do not install the inverter in areas with corrosive substances (such as sulfuric
acid, hydrochloric acid, nitric acid, hydrogen sulde, and chlorine) to avoid
inverter failure caused by corrosion, which is not covered under the warranty.
● If the equipment is installed in a place with abundant vegetation, in addition
to routine weeding, harden the ground underneath the equipment using
cement or gravel (the area shall be greater than or equal to 3 m x 2.5 m).
● If the inverter is installed in public places (such as parking lots, stations, and
factories) other than working and living areas, install a protective net outside
the inverter and set up a safety warning sign to isolate the inverter. This is to
avoid personal injury or property loss caused by accidental contact by non-
professionals or other reasons during device operation.
● Keep the inverter out of reach of children.
● Do not install the inverter outdoors in salt-aected areas because it will be
corroded there and may cause re. A salt-aected area refers to a region
within 500 m of the coast or prone to sea breeze. Regions prone to sea breeze
vary with weather conditions (such as typhoons and monsoons) or terrains
(such as dams and hills).
The inverter shall be physically isolated from third-party wireless communications facilities
and residential environments at a distance greater than 30 m.
Installation Environment Requirements
The inverter provides self-protection in high-temperature environments. Its energy
yield may decrease as the ambient temperature increases. Ensure that the
following installation requirements are met:
● Install the inverter in a well-ventilated environment to ensure good heat
dissipation.
● If the device is installed in an enclosed environment, the heat dissipation
equipment or ventilation equipment shall be installed. The indoor ambient
temperature must not be higher than the outdoor ambient temperature.
● Install the inverter in a sheltered place to prevent exposure to direct sunlight.
● Reserve sucient clearance around the inverter for installation and heat
dissipation. The impact of environment changes on the clearance for heat
dissipation needs be considered during design. The clearance around the
inverter may become insucient for reasons such as rotation axis change.
