Calibration of the thermal relay
The thermal relay is used to avoid damage to the motor owing to
a strong increase in absorption or the lack of a phase.
For the calibration, refer to the electrical wiring.
If the minimum value of the scale of the thermal relay is greater
than the rating absorption of the motor, protection is still ensured.
This arises when the power supply of the motor is 400 V.
To reset, in the case of an intervention of the thermal relay, press
the button 1)(Fig. 29).
