Corrosion in the machine
Condensation can lead to corrosion in the machine.
• Select the intake temperatures so that no condensation forms on the surface of the
The rated motor data refer to operation at a coolant intake temperature of 35 °C. If the intake
temperature is different, the continuous motor current changes as shown below.
Note
For a cooler intake temperature of < 35 °C, the possible continuous motor current is greater
than the rated current I
Larger cable cross-sections may be required. This means that you must take into account
the rated current of the cables.
The following diagram shows the dependency of the relative continuous primary section
