3.3 Installation Direction and Space Requirements
To achieve good cooling efficiency, install the inverter perpendicularly and always provide the
following space to allow normal heat dissipation. The requirements on mounting space and
clearance are shown in Figure 3-1and Table 3-1.

Table 3-1 Installation dimension of the inverters
Inverter power A(left and right) B(up and down)
≤55kW ≥50mm ≥100mm
≥75kW ≥150mm ≥350mm
When one inverter is mounted on the top of the other, an air flow diverting plate should be fixed in
between. Just as shown in Figure 3-2.
