1.4.1 - General
b - Installation in a non-ventilated cubicle
The minimum required surface area for heat
exchange is calculated from the following equation :
where :
Pj = loss from all heat-producing equipment (W).
Tj = maximum permissible ambient operating
temperature (
°
C).
Tamb = maximum ambient external temperature (
°
C).
k = thermal transmission cœfficient.
S = heat exchange area (m
2
).
k = 5.5 for 2mm thick sheet steel.
Example : installation of an FMV in a non-ventilated IP 54
cubicle (cubicle placed against a wall).
Pj = 114W (FMV 2107 2,5M) for switching F = 11.7kHz.
Tj = 40
°
C.
Tamb = 30
°
C for example.
k = 5.5.
The calculated heat exchange area is S = 2.07m
2
and
S = 2 (AB) + AC + BC.
Taking the following values for A and B :
A = 1.8 m (height) - B = 0.6 m (depth),
the minimum calculation for C = 0.39 m.
c - Installation in a ventilated cubicle
If it is possible to use forced ventilation (FV) the size of
the cubicle can be reduced. A minimum space of 100 mm
should be left around the inverter.
The flow rate of FV in m
3
/h is calculated using the
formula
for the previous example.

1.4.2 - Installation in a cubicle
Installing the inverter in a cubicle calls for special precautions with regard to the size of the enclosure. It is important to check
that there is sufficient heat dissipation.
