Chapter 2 Mechanical Installation
2.2.3 Multiple Inverters Installed Vertically: In occasions where multiple inverters need installed vertically
next to each other, the lower row of inverters' dissipation of heat will cause a temperature rise of the upper
row of inverters, resulting in the overheat/overload errors of the upper row of inverters. Therefore, it is
recommended to take measures such as installing a insulation plate in between as the following the figure:
Note: Please install an insulation plate according to the figure above when installing two inverters
vertically next to each other.
Attention Matters for Heat Dissipation of Mechanically Mounting:
1) The inverter should be installed vertically for heat dissipation but cannot be put upside down.
Installing the inverters side by side is highly recommended for installing a number of them in one
cabinet. Please refer to figure 3-1 when installing the insulation plate
2) Follow Figure3.1 to ensure the dissipation space for the inverters. The heat dissipation of other
machines in the cabinet should be considered as well.
3) The mounting bracket must be flame retardant material.
4) Installing the radiator outside the cabinet is recommended if there are metal dusts at the installation
location. Please make sure the sealed cabinet space is as large as possible.
