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
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. In case a different mains
voltage is present, the jumpers on the terminal
board must be rearranged as shown in the
diagram. The ground cable must be connected to
terminal
. After connecting the supply cable to
the terminal board, secure it with a junction clamp.
