Note: When the inverter power is not higher 
than 22kW, the A size can be omitted.    When 
the inverter power is higher than 22kW, the A 
size shall be higher than 50mm.   
 Note:When inverters are 
distributed up and down, mount 
splitter for heat insulation as shown 
in the diagram.   
 
Heatsink shall be taken into account during the mechanical installation.  Due attention shall 
be paid to the following items:       
1) Install the inverter vertically so that the heat may be expelled from the top. However, the 
equipment cannot be installed upside down.    If there are multiple inverters, parallel installation is 
a better choice.  Fig.3-1 MD300 Inverter Installation DiagramIn applications where the inverter 
need to be installed up and down, please refer to Fig.3-1 “MD300 Inverter Installation Diagram” for 
installing heat insulation splitter.
