Cooling
The heat sources inside the equipment correspond to the inverter bridge
(IGBTs), rectifier bridge and the input filter.
The drive has at least one cooling fan (this varies depending on the drive
size) at the bottom, the hot air is then dissipated through the gratings on the
top side.

It is possible to replace the cooling fans without dismounting the whole

the connector.
