5.2 Fan cooling
5.2.1 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 in the table below.
If several units are mounted on top of each other, the required free space equals 2 * C (see figure
below). 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 approx. 2.5% of the nominal capacity.
