Fan Cooling

Frames FI9 to FI14

Enough free space must be left around the inverter to ensure sufficient air circulation and
cooling. You will find the required dimensions for free space Table 2-5.

If several units are mounted on top of each other, the required free space equals 2 * C (see
Figure 2-5). Moreover, the outlet air used for cooling by the lower unit must be directed away
from the air intake of the upper unit. When planning the cooling for the space, take into
consideration that the inverter’s heat loss is 2.5% of the nominal capacity.
