2.3 Cabinet mounting
2.3.1 Cooling
If the variable speed drive is installed in a cabinet, the rate of
airflow supplied by the cooling fans must be taken into
consideration.
2.3.2 Recommended free space in
front of cabinet
All cabinet mounted AC drives are designed in modules, so
called PEBBs. These PEBBs can be folded out to be
replaced. To be able to remove a PEBB in the future, we
recommend 1.30 meter free space in front of the cabinet, see
Fig. 14.
