4.10 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 table given in electrical layout
no. 6 in Appendix A.
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) of Fig. 22.
