The appliance is designed to be connected to 230 V
monophase electricity supply.
The connection must be carried out in compliance with
the laws and regulations in force.
Before the appliance is connected:
1) check that the main fuse and the domestic installation
can support the load (see the rating label);
2) check that the power supply is properly earthed in
compliance with the current rules;
3) check the socket or the double pole switch used for
the electrical connection can be easily reached with
the appliance built in the forniture unit.
The appliance is supplied with a connection cable. This
has to be provided with a proper plug, able to support the
load marked on the identification plate. To connect the
plug to the cable, follow the recommendation given in Fig.
4. The plug has to be fitted in a proper socket.
If connecting the appliance directly to the electric system,
it is necessary that you install a double pole switch
between the appliance and the electricity supply, with a
minimum gap of 3 mm. between the switch contacts and
of a type suitable for the required load in compliance with
the current rules.
The connection cable has to be placed in order that, in
each part, it cannot reach a temperature 90 °C higher than
the room temperature.
The brown coloured phase cable (fitted in the terminal
block contact marked with "L") must always be connected
to the network phase.
REPLACEMENT OF THE VOLTAGE CABLE
The connection of the voltage cable to the appliance's
terminal block is of type "Y". This means that its
replacement requires the specific equipment of a
technician.
In this case, only cable type H05V
2
V
2
-F T90 must be
used. The cable section must be suitable to the voltage
and the working temperature.
The yellow/green earth wire must be approximately 2 cm.
longer than the phase wires (Fig. 4).
To open the terminal block and reach the terminals,
proceed as follows:
insert the point of a screwdriver into the visible
protrunding part of the terminal block;
exert a light pressure and lift (Fig. 5)
