6.4 - POWER CONNECTIONS
(Wiring diagram - pp. 7, 8)
The appliance must be connected to the power supply in
accordance with approved standards.
• The appliances are delivered prearranged for operation with
a power supply of 400 V 3N~ and can be transformed for
operation with a voltage of 230 V 3~.
• For any transformation, it is sufficient to modify the terminal
board and resistance element connections as shown in the
wiring diagram.
• The connection to the power supply must include the instal-
lation of an automatic circuit breaker of suitable capacity with
an opening distance between the contacts of at least 3 mm.
In addition, the supply voltage, with the machine in opera-
tion, must not deviate from the nominal voltage value of ±
10%.
• The flexible cable for connecting to the power supply must
have characteristics of not less than type HO7RN-F rubber
insulation and a nominal cross section suitable for the maxi-
mum current input.
• The appliance must be connected to an efficient grounding
system. For this purpose, the terminal board contains a ter-
minal marked with the grounding symbol
grounding conductor must be connected.
• The appliance must be included in an equipotential system.
The connection must be made with the set screw marked
with the symbol
. The equipotential conductor must have
a cross section of 10 mm
• The grounding system and the equipotential system must
meet the standards in force and must be checked from time
to time.
The manufacturer declines any liability if these safety
precautions are not complied with.

6.4.1 - Installation of equipotential and power cable
nection
To access the equipotential and power supply terminal boards,
proceed as follows:
• Connect the equipotential cable to the terminal
• Open the electrical cabinet door. Insert the cable and con-
nect it to the terminals marked with the symbols U-V-W-N-
PE as illustrated in the wiring diagram and fasten it with the
cable clamp.
7 - CHECKING THE OPERATION
ATTENTION!
Check that the jacket is filled with water up to the maxi-
mum level (see Chapter II, Par. 3).
• Start the appliance according to operating instructions.
• Check with a snap-on ammeter that the power absorption of
the three phases is balanced and according to the power
installed.
• Check the calibration of the safety valve.
• Check the lid balancing system.
• Train the user on the operation and maintenance of the ap-
pliance with the help of the operator's manual; stress in par-
ticular the importance of all the points of caution to comply
with for the proper use of the appliance.
