Fan Cooling

Frames FR4 to FR8

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 Table 2-6.

If several units are mounted on top of each other, the required free space equals C + D (Figure

2-6). 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.
