Emergency operation
The electric machine should be operated within the operation limits and in the conditions
speci ed by the manufacturer. However, it can be limitedly used in the following fault/emergency
situations.
Cooling of the electric machine fails
The cooling system failure can be caused by dregs (sediment) accumulating to the cooling system
tubes. Try opening the possible blockage by changing the coolant ow direction. See also Chapter
Cooling system maintenance .
If the cooling of the electric machine fails, limited operation is still possible with no coolant ow.
The operation speed must be limited to half (1/2) of the rated speed and maximum 20 % of the
nominal torque may be used. In such case, the electric machine may be operated for maximum
one hour. Repair the cooling system as soon as possible. For further information, contact
Danfoss representative.
