NOTE 1: The inverter should be installed in a locked enclosure that meets the requirements in

IP4X.
The higher the ambient temperature inside the inverter, the shorter its life will be. If
a heat generating unit is used near the inverter, try to keep it as far away as possible.
Also, when installing the inverter in a box, be sure to carefully consider ventilation
and the dimensions.
