When the coolant temperature increases then the rated power PN (see Table 1-6)<br />
decreases.<br />

Cooling system<br />
A cooling system (i.e. heat exchanger) must be used in order to guarantee a coolant<br />
intake temperature of 30 �C. It is possible to operate several motors from a<br />
single cooling system.<br />
The cooling system is not part of the motor scope of supply. A list of addresses of<br />
cooling system manufacturers is provided in Catalog NC 60.<br />
