Coolant intake temperature<br />

Recommendation: up to 30 °C<br />

1-24<br />

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 />
