Unit installation: When the inverter power is not greater than 22kW cannot consider the A
size. When greater than 22kW, A should be greater than 50mm. Up and down installation:
Install the thermal insulation baffle when the inverter is installed up and down
Power level
≤15kW
18.5Kw~30kW
≥37kW
3.1.2 Mechanical installation need to focus on the heat problem. So please note the
following:
1) Please install the inverter vertically, so that the heat can be distributed upwards. But
cannot be inverted. If the cabinet has more frequency converter, it is best to install side by
side. Please refer to Figure 3-1 for the installation of the insulation baffle.
2) Installation space Follow the example shown in Figure 3-1 to ensure the cooling space of
the inverter. However, please consider the layout of the cabinet when the heat dissipation of
other devices.
3) The mounting bracket must be flame retardant.
4) For metal dust applications, it is recommended to install the radiator cabinet. At this time
fully sealed cabinet space as much as possible.
