Electrical connections
Connection to the power supply must be carried out in
conformity with the current regulations and provisions in
the country of use.
•
Make sure the machine power supply voltage speci-
fied on the rating plate (Table 1) matches the mains
voltage.
•
Make sure the system power supply is arranged and
able to take the actual current load and that it is exe-
cuted in a workmanlike manner according to the reg-
ulations in force in the country of use.
•
The earth wire at the terminal end must be longer
(max. 3/4” [20 mm]) than the phase wires.
•
Connect the earth wire of the power supply cable to
an efficient earth clamp. The appliance must also be
included in a unipotential system, the connection
being made through the screw “EQ” (see pargraph
E6.2 Installation diagram) marked with the symbol
“
”. The unipotential wire must have a cross section
of 10 mm

Power supply 208V 3ph or 240V 3ph
Figure 11 208V 3ph o 240V 3ph
Open the power supply terminal board and insert the jum-
pers provided as follows: one jumper between terminals 1
and 2, one between terminals 3 and 4 and another between
terminals 5 and 6. Using a suitable power supply cable (see
technical data table), connect the three phases to terminals
1, 3 and 5 and the earth wire to the terminal
.

Energy control arrangement
The machine is arranged for external control of energy
consumption.
Figure 12 Energy control
Connect the energy peak controller across terminals 11
and 12 (Figure 12).
Safety devices
•
An automatic reset thermoamperometric protective
device incorporated in the windings of the electric
pump cuts off the electricity supply in the case of mal-
functioning.
•
In the event of water mains failure, a device prevents
water in the boiler from returning into the mains.
•
An overflow pipe, connected to the drainage outlet,
maintains the water in the tank at a constant level.
Failure to comply with safety rules and regulations
relieves the manufacturer of all liability.
E9
HACCP arrangement
The machine is arranged for the HACCP connection it is
still necessary to order the network connection cable.
Connect the HACCP network to terminals 2 and 3 of
connector X4.

IMPORTANT!
Work on the electrical systems must only
be carried out by a qualified electrician.

CAUTION
A normally open (n.o.) contact of the con-
troller must be connected across termi-
nals 11 and 12. When this contact closes
the boiler heating elements are discon-
nected. Using the dishwasher in these
conditions may increase the cycle time.
IMPORTANT!
If the power cable is damaged it must be
replaced by the After-Sales Service or in
any case by qualified personnel, in order
prevent any risk.
