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
and yellow ground wire must not be
interrupted by the switch, and 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 400V tri-phase with neutral
wire (Fig. 13). In case a different mains
voltage is present, the jumpers on the
terminal board must be rearranged as
shown in the diagram (Fig. 14). The ground
cable must be connected to terminal
.
After connecting the supply cable to the
terminal board, secure it with a junction
clamp.
