Power supply to the auxiliary circuit
The power supply to the auxiliary circuit is 220V for all the units. Connection to the power circuit is inside the panel and is
carried out in the factory. The compressor oil heaters, the protections against compressor over temperature and the
cooling water safety indicator are connected so as to always be operative, as long as the electrical panel is power
supplied.
