Electrical connections
Connection to the power supply must be carried out in
conformity with the current regulations and provisions
in the country of use.
IMPORTANT!
Work on the electrical systems
must only be carried out by a
qualified electrician.
•
Make sure the appliance power supply voltage
specified 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
executed in a workmanlike manner according to the
regulations in force in the country of use.
•
The earth wire at the terminal end must be longer
(max. 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 con-
nection being made through the screw "EQ" (see
pargraph F6.2 Installation diagrams) marked with
the symbol "
". The unipotential wire must have a
cross section of 10 mm

Open the power supply terminal board and insert the
jumpers provided as follows: one jumper between termi-
nals 2 and 4 and another between terminals 4 and 6.
Using a suitable power supply cable (see technical data
table), connect the three phases to terminals 1, 3 and 5,
the neutral to terminal 6 and the earth wire to the termi-
nal

Energy control arrangement
The appliance is arranged for external control of
energy consumption.

Figure 14 Energy control
Connect the energy peak controller across terminals
11 and 12 (Figure 14).
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 appliance in these con-
ditions may increase the cycle time.
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
malfunctioning.
•
In the event of water mains failure, a device pre-
vents water in the boiler from returning into the
mains.
Failure to comply with safety rules and regulations
relieves the manufacturer of all liability.
