The cooling air for the power unit is drawn in from the front through the ventilation grilles in
the lower part of the cabinet doors. The warmed air is discharged through the perforated top
cover or the ventilation grilles in the hood (with options M23/M43/M54 for degrees of
protection IP23/IP43/IP54). Cooling air can also be supplied from below through raised floors
or air ducts, for example. To allow this, you have to create openings in the sectioned base
plate.
In a residential environment this product can cause high-frequency disturbances, which
may make interference-suppression measures necessary.
