NOTE:
It is also suggested to verify that the
characteristics of the mains power supply are
adequate for the power consumption indi-
cated in the table of electrical data.
IMPORTANT: Before carrying out any opera-
tion on electrical parts, make sure the power
supply is disconnected. Check that the mains
supply voltage corresponds to the nominal
