Mix additives in with the cooling water in appropriate quantities to protect against corrosion
and inhibit the growth of algae. The type and quantity of additive should be taken from the
respective manufacturer's specifications for these additives and the particular ambient
conditions.
Cooling unit
The use of a correspondingly dimensioned cooling unit ensures the coolant inlet temperature
of 25°C. You can operate several motors and/or the converter on one cooling unit.
Use a closed cooling cooling circuit. This will prevent deposits in the cooling circuit, cooling is
then permanently guaranteed.
The cooling unit is not part of the motor's scope of delivery.
