Installing
Ensure inverter not have electrical connections and electricity before installing.
Danger
！
The solar cell arrays should be covered with opaque materials when installing the
photovoltaic arrays during the day, otherwise the solar cell arrays will generate high
voltage, causing person casualties.
Danger
！
When the input AC end is connected to the inverter, the ac input side circuit breaker
should be disconnected, otherwise the AC input will produce dangerous voltage,
causing personal casualties.Do not conduct wiring operations by non-professionals.
