The motor can be destroyed as a result of overtemperature if you do not correctly connect the
temperature sensors.
• When connecting temperature sensor cables with open conductor ends, pay attention to
the correct assignment of conductor colors.
Note
Observe the polarity
Carefully note the polarity when connecting the KTY.
PTC elements must be evaluated for thermal motor protection.
