3.1.2 CE marking
Use of machines without CE marking
Machines without CE marking are intended for operation outside the European Economic Area (EEA). Do not use any
machines without a CE marking in the EEA!
3.2 Design
3.2.1 Machine design
Machines of this series are low-voltage three-phase induction or reluctance-synchronous machines with a cylindrical shaft
end and keyway. They can be supplied as single-speed machines with different efficiency classes or as pole changing
machines for several speeds.
In the case of machines with feet (IM B3 type of construction), the feet are cast.
3.2.2 Regulations
The regulations and standards used as the basis for designing and testing this machine are stamped on the rating plate. The
machine design basically complies with the following standards:

3.2.3 Cooling and ventilation
Forced ventilation (optional): Type of cooling IC 416 in accordance with EN / IEC 60034-6
Cooling that does not depend on the speed is achieved by means of a unit that is independent of the motor operating state
(forced ventilation). This unit is closed to the outside by a fan cover. It has its own main drive with fan impeller which creates
the cooling air flow required for cooling the motor.
