46 Planning the cabinet installation

Cabinets with multiple modules
The hot air from a drive module must not enter another module. In a cabinet with
multiple modules, the practical way is to install a wall to separate the cool area (at the
front part of the cabinet) from the hot area (back part). The wall 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 using separate airflow guides. See the example below.
