Recommended material for connecting coolers
NOTICE
Corrosion as a result of unsuitable materials used to connect the cooler
Corrosion damage can occur if you use unsuitable materials to connect to the cooler.
•
Coolant inlet temperature
NOTICE
Corrosion in the machine
Condensation can lead to corrosion in the machine.
•
The rated motor data refer to operation at a coolant inlet temperature of 35 °C. If the inlet
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 I
Larger cable cross-sections may be required. This means that you must take into account
the rated current of the cables.

We recommend that you use brass or stainless steel fittings when connecting the
cooler.
Choose inlet temperatures that prevent condensation from forming on the surface of the
motor. Condensation does not occur if the intake temperature T
ambient temperature – or corresponds to the ambient temperature.
