4.3 Mechanical installation
The material for fixing the inverter and the installation mode vary with the different installation sites.
It is recommended to install the inverter vertically to the firm wall or metal bracket. Here we take
wall installation as an example to introduce the installation matters of the inverter.
As shown in the Figure 4.4, the installation of the inverter should be vertical to the horizontal
surface.
