6 • ELECTRICAL CONNECTIONS AND EQUIPOTENTIAL BONDING
6.1 • As this oven is a type Y appliance (oven
without power cable and plug), the cable
and other hardware needed to make
the connection to the electrical power
supply must be provided by the installer.
The cable must satisfy the requirements
indicated in table 1 "General data". As
already mentioned, the oven must be
connected to the power supply by way
of a multiple pole main isolating switch
ensuring a gap between open contacts of
at least 3 mm on each pole.
6.2 • To access the power terminal block,
the oven panel must be removed by
unscrewing the fastening screws.
6.3 • The cable must be fed in through the
clamp from the back. The individual wires
are then fastened to the corresponding
terminals of the terminal board. The earth
wire must be longer than the other wires,
so that in the event of the cable being
jerked or the clamp broken, the live wires
will disconnect first.
Check the efficiency of the isolating switch.
6.4 • Connect the power cable according to the
following diagrams:
