SK 54xE – Users Manual for Frequency Inverters   
30    BU 0505 EN-3021 
2.1  SK 5xxE, standard version 
Normally the frequency inverter is mounted directly on the rear wall of a 
control cabinet. For this, two, of for Size 5 to 7 four, suitable wall-mounting 
brackets are supplied, which must be pushed into the heat sink on the rear 
of the inverter. Above Size 8, the mounting device is already integrated. 
Alternatively, for Size 1 to 4 the wall mounting brackets can be inserted at 
the side of the cooling element in order to minimise the necessary depth of 
the control cabinet. 
In general, care must 
be taken that the rear of the cooling element is 
covered with a flat surface and that the device is mounted vertically. This 
enables optimum convection, which ensures fault-free operation.
