INSTALLATION
Electrical connection
Warning!
All electrical work should be carried out by a suitably qualified and authorised electrician. No
alterations or wilful changes in the electricity supply should be carried out.
Fitting guidelines
The cooker is manufactured to work with three–phase alternating current (400V 3N~50Hz).
The voltage rating of the cooker heating elements is 230V. Adapting the cooker to operate
with one-phase current is possible by apropriate bridging in the connection box according
to the connection diagram below. The connection diagram is also found on the cover of the
connection box. Remember that the connection wire should match the connection type and
the power rating of the cooker.
The connection cable must be secured in a strain–relief clamp.
Warning!
Remember to connect the safety circuit to the connection box terminal marked with
. The
electricity supply for the cooker must have a safety switch which enables the power to be cut
off in case of emergency. The distance between the working contacts of the safety switch
must be at least 3 mm.
Before connecting the cooker to the power supply it is important to read the information on
the data plate and the connection diagram.
