Guiding the cooling air flow
The hot air from an inverter module must not be allowed to enter another module. In
a cubicle with multiple modules, a practical way of achieving this is to install a
mounting plate to separate the cool area (at the front part of the cubicle) from the hot
area (back part). The mounting plate can be fastened to two vertical pillars on both
left and right. Since the air outlet at the top of the modules points directly upwards,
the air must be guided to the hot area. See the example below.
