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.
