5.3 ELECTRIC CONNECTIONS
Before setting up the machine verify:
If the installation has a device which assures the disconnection from the power
grid according to the rules of installation.
If the power grid and the RCD are conform to the characteristics of the machi-
ne (see technical characteristics plate).
Power cord must be connected directly to the electric grid, according with the
scheme below.
Electric Scheme
Electrical safety of the machine is assured only when connected to an effecti-
ve earthing, as predicted by the electrical safety regulations. It is necessary to
verify this requirement and in case of doubt, demand an inspection control of
the power grid by professionally qualifi ed personnel.
CA - Power Cable; I - General ON/OFF switch; C - Contactor; A1 and A2 – Contactor power; PC – Control
Board; Cont1 – Group1 volumetric meter; Cont2 - volumetric group2 meter; PP - Power Plate; ELVL 1 – Group
1 solenoid valve; ELVL 2 – Group 2 solenoid valve; ELVLB – Pump solenoid valve; ELVL H2O – Water solenoid
valve; M - Motor; RAC - heating element for cups; RC - heating element of boiler; TS - Safety thermostat;
CLD - Boiler; NTC - Temperature probe; SND1 – Maximum level probe; SND2 – Minimum level probe
The manufacturer cannot be considered
liable for eventual damages caused by the
lack of earthing on the machine connection.
