Cooling
Self-cooling
The motors are designed for self-cooling.
The rated data only apply if the ambient temperature does not exceed 40 °C (104 °F) as a
result of the installation conditions.
Recommendation:
Maintain a gap of 100 mm to adjacent components on at least three sides in order to allow
waste heat to dissipate.
Forced ventilation

The ventilation unit can, in principle, be retrofitted. This is performed exclusively by
SIEMENS Service.
Note: changed plug size/winding.
Do not take heated outgoing air in again to cool the motor.
Minimum clearances of the air exhaust outlet from customized components:
Water-cooling
Closed coolant circuit with heat exchange unit required. Water cooling cannot be retrofitted.
If the cooling circuit has been filled and frost can be expected, a commercially available
antifreeze agent must be added. Please refer to the manufacturer's documentation for
usage and dosage (max. 50 %). Do not mix different types of antifreeze.
Do not use any nonferrous metals (e.g. copper or brass pipework) in the cooling circuit
(electrolyte formation).
