In the case of open system cubicles, natural convection provides for heat dissipation. The vast majority of the heat is removed by the external air flowing through the cubicle.
To this end, the cubicle must be fitted with a perforated roof panel or a ventilation roof. Attention is drawn to the special design (SBL) of the ventilation slots in the door and in the roof panel. These slots can be supplied for degrees of protection IP30 and IP40.
In the past, ventilation slots for degree of protection IP40 were backed up with an additional frame and fine-meshed grille. This is no longer necessary.
The existing ventilation slots for 8MC and 8MF system cubicles with degrees of protection IP20 and IP40, together with the corresponding roof panel, can still be supplied. Perforation in "Masterdrive" design similarly remains available.
