Cooling Air Requirements - Siemens SINAMICS G130 Engineering Manual

Cooling air requirements

A specific quantity of cooling air must be supplied to S120 Cabinet Modules. This cooling air requirement is always
important, even under challenging boundary conditions. The cooling air is drawn in from the front through the
ventilation grilles in the lower part of the cabinet doors. The warmed air is expelled through the perforated top cover
or the ventilation grilles 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 (cabinet door closed).
The cooling air requirement of individual Cabinet Modules is specified in the tables below:
