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 supplied with a connection
cable incorporating a 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 2-3 cm longer
than the phase and neutral wires. 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 400 V 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
connected to terminal
. After connecting
the supply cable to the terminal board,
secure it with a junction clamp.
