Inside the cabinet

Prevent hot air circulation inside the cabinet with leak-proof air baffle plates. No
gaskets are usually required.
When several modules are installed vertically in one cabinet, the hot air from one
module must not be allowed to enter another module. In a cabinet 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 cabinet) 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 cabinet layout examples below.
