Between the oven and the power grid there must be a general omnipolar switch with a contact
distance of at least 3mm, with a capacity close to the load and equipped with the appropriate
protection devices.
It is necessary to provide the appropriate automatic differential protection devices, able to guarantee
protection against direct and indirect contact with the live parts and the ground fault currents in
accordance with the applicable Regulations; the maximum leakage current admitted is of 1 mA/kW.
This switch must be installed in the permanent electrical system of the room where the oven is
installed and in close proximity to the oven itself so that operators have easy access to it.
For the dimensions of the power supply line, of the general switch and the cable refer to the data
given in the technical data table (see paragraph 1.3).
In order to connect or replace the power supply cable to the terminal box of the oven proceed
as follows:
1)
Connect the terminal box placed on the backside of the oven to the wires of the electric cable,
as indicated in the illustrated electrical diagram.
Make sure the yellow/green grounding wire is longer than the others (phase and neutral) of
about 3 cms so that in case of pulling it is going to be the last one to break loose
guaranteeing the security of the protection against electric shock.
2)
Block the cable and close the lid of the terminal box.
Grounding
The oven must be connected to an efficient grounding system.
The yellow/green wire of the supply cable must be secured in the clamp marked with the grounding
symbol
The oven must be included in an equipotential system the connection of which will have to be
performed with a cable having a minimum section of 10 mm2 connected to the clamp marked with the
symbol placed on the backside of the oven.
3.3 - Safety devices
The oven is equipped with the following protection and safety devices:
Cabinet safety thermostat (if present): in case of overheating of the cooking cabinet, it intervenes
by cutting off the chamber heating.
The safety thermostat (
F1 - Fig. 5
) may be reactivated only in manual by pressing the red button
after having removed the back panel in order to reach the component. Before executing the
operation make sure you have disconnected the power supply.
Door switch that interrupts the operation of the oven when the door is opened: both the heating
system and the cabinet ventilation fan motor.
Protection grilles preventing access to the moving parts of the cooking cabinet.
CAUTION!
All potential reactivation operations must be performed by specialized technical personnel
after the elimination of the causes of interruption.
