Instructions for the installer
The instructions given below are
designed specifically for a qualified
installer and should aid him or her to
perform all installation, adjustment,
and maintenance operations with
absolute precision and in compliance
with all current legislation and
regulations. We strongly recommend
that all operations for the installation
of your cooker be carryed out by
Qualified Personnel in accordance
with existing rules and regulations.
Electrical connection
Prior to making the electrical connection,
make sure that:
— the protection fuse and the domestic
wiring system are suitable to carry the
total electric load of the oven (see rating
plate);
— your domestic wiring system has an
efficient earth connection in compliance
with rules and laws in force;
— the wall socket or the omnipole switch
used for the electrical connection can
easily be reached after the oven is built
in.
This appliance is delivered without an
electric supply cable, therefore, you will have
to fit to it a supply cable with standard plug,
suitable for the total electric load shown on
the rating plate. The plug is to be inserted
into a suitable wall socket. If you require a
direct connection to the electric network
(mains), it will be necessary to fit between
the appliance and the mains an omnipole
switch, with a minimum gap between
contacts of 3 mm, suitable for the required
load and in compliance with rules in force.
The green & yellow ground wire must not be
interrupted by the switch and it should be 2-
62
3 cm. longer than the other cables. The
supply cable must in all cases be laid out in
such a way as to ensure that it does not
reach at any given point a temperature 50°C
higher than the ambient temperature.
Suitable power supply cables are the
following types, considering the respective
necessary section of cable: H07 RN-F, H05
RN-F, H05 RR-F, H05 VV-F, H05 V2V2-F
(T90), H05 BB-F.
Connecting the terminal board
The appliance incorporates an easily
accessible 6-pole terminal board whose
jumpers (bridges) are already pre-set for
operation on 400V tri-phase with neutral wire
(Fig. 10). In case a different mains voltage
is present, the jumpers on the terminal board
must be rearranged as shown in the diagram
(Fig. 11). The ground cable must be
