be returned to an authorized dealer or approved collection and recycling facility.
All operations including transport, installation, start-up
,
and maintenance must be carried out by
qualified, trained personnel.
Before installation, check the unit to ensure

integrity or safety clearances. Choose installation location carefully and
adhere to specified cooling requirements. Unauthorized removal of necessary protections,
improper use, incorrect installatio
n/ o
peration may lead to serious safety and shock hazards
or equipment damage.
Before connecting the Microinverter to the power distribution grid, contact the local power
distribution grid company to get appropriate approvals. This connection must be made only by qualified
technical personnel. It is the responsibility of the installer to provide external disconnect switches and
Over current Protection Devices (OCPD).
Only one photovoltaic module can be connected to one input of the inverter. Do not connect
batteries or other sources of power supply. The inverter can be used only if all the technical
characteristics are observed and applied.
Do not install the equipment in adverse environment
al
conditions such as flammable,
explosive, corrosive, extreme high
