4.6  Compressor motor circuit 

breaker calibration

4.7  Closing the electrical panel

Below we show step by step how to correctly calibrate motor circuit breaker dedicated to the 

compressor.

Once the electrical connections, checks and calibrations have been completed, the electrical panel 

can be closed.

Fig 15. When the system is started for first time it’s 
suggested to calibrate the motor circuit breaker on the
compressor power circuits. Using an ammeter verify the 
effective absorption.

Fig 18. Close the front panel, making sure that all cables 
are inside the box and that the box gasket is correctly 
housed.

Fig 20. Power up the panel and carry out thorough reading/ 
programming of all the parameters.

Fig 17. To carry out the calibration, use the adjustment 
screw on the front of the motor protection switch.

Fig 16. Make the motor circuit breaker calibration 
basing on the measured absorption. Any way the set up 
value must not be higher than the one expected by the 
compressor manufacturer.

Caution:

 incorrect calibration may cause compressor 

failure or unwanted action of the motor protection switch.

Fig 19. Tighten the front panel using the 4 screws. Refit the 
cover of the screws on the right side.
