temperature range
Ambient temperature:
0 °C to +40 °C
Temperature class:
TF 110
Media temperature:
+2 °C to +110 °C
To avoid condensation forming in the terminal box
and stator, the media temperature must always be
the same or higher than the ambient temperature.

motor protection
The motor winding is designed to be blocking
current-proof. Therefore motor protection is not
required.
