7.2.2.5 Cooling air requirements of air-cooled S120 Cabinet Modules
A specific quantity of cooling air must be supplied to air-cooled S120 Cabinet Modules. This volume of cooling air
must always be supplied, even under challenging boundary conditions. The cooling air is drawn in from the front
through the ventilation openings in the lower part of the cabinet doors. The heated air is expelled through the
perforated top cover or the ventilation openings in the top cover (with option M23/ M43/ M54). The minimum ceiling
height (for unhindered air outlet) specified in the dimension drawings must be observed. Cooling air can also be
supplied from below through raised floors or air ducts, for example. Openings in the 3-section baseplate must be
made for this purpose. Please also refer to the supplementary information for option M59 (Closed cabinet doors).
The tables below show the cooling air requirements of units in the Cabinet Modules range:
