Observe the following points during non-immersed operation:
▪ Operating mode "non-immersed" indicated
The motor emerging in "non-immersed" operating mode is permissible.
▪ Operating mode: "non-immersed" not indicated
If the motor is fitted with a temperature controller (2-circuit temperature monitoring),
emergence of the motor is permitted. Automatic reactivation can be initiated after the
motor has cooled down using the low temperature. The unit is forced to deactivate with
reactivation lock once the high-temperature has been reached. CAUTION! To protect
the motor winding from overheating, the motor must be equipped with a temper-
ature controller! If only one temperature limiter is installed, the motor must not
emerge during operation.
▪ Max. fluid and ambient temperature: The maximum ambient temperature corresponds
to the maximum fluid temperature shown on the rating plate.
CAUTION! The following applies to motor T 12: During non-immersed operation, the
fluid temperature and ambient temperature must not exceed 30 °C!
Operation on the frequency converter is permitted. Refer to the appendix for the relev-
ant requirements!
