The specialized installer must install the following components in accordance with the regulations of the country
where the equipment is used:
A power cable with suitable plug and socket.
Line switch/disconnector.
Thermal release and differential switch with sensitivity characteristics proportional to the leakage current of
the resistors.
The components must be installed by the user near the oven's installation point. The appliance must be
grounded through a reliable grounding system. A thorough visual and instrumental check of the conditions
and characteristics of the grounding system is necessary, restoring any necessary elements.
Perform the connection according to the specified technical procedures, ensuring both the cyclic phase
connection sequence and the color coding of the conductors are respected:
L1 –
Phase
R –
Black/Grey/Brown color;
L2 –
Phase
S –
Black/Grey/Brown color;
L3 –
Phase
T –
Black/Grey/Brown color;
N –
neutral - Blue. Position of terminal strip 4-5
connected with a bridge;
Earth = protective conductor - Striped yellow/green

Models P134H, P134HA, P234H, P150H and PI 50HA
use oil-resistant H05RN-F cables with 3x1.5 mm2
section and equipped with 220/230V Schuko plugs.
After installing the protection devices for the oven power supply, it is necessary to test the efficiency of
the residual-current circuit breaker using an appropriate instrument. Check that there are no inflammable
materials or objects of any kind inside the oven. Once the necessary checks have been carried out, the
oven can be switched on for preliminary testing. No protective panel needs to be removed.
Turn the thermostat knob to the middle of the graduated scale. Check the current absorption and proper
operation of all the indicator lights on the oven. Wait for the thermostat to interrupt the circuit and
switch the oven off. Following this test, it is possible to use the oven.
At the end of the connection of the equipment and the functional testing of the oven, the installer
must issue the required declaration regarding the perfect success of the work carried out.
N.B. For professional ovens only: The appliance must be connected to an equipotential system
whose effectiveness must be appropriately verified according to the regulations in force.
This connection must be made between different devices using the appropriate terminal, marked with the symbol
in the figure above and located on the back of the oven. The equipment must be connected to the earth line of
the electrical network, the equipotential conductor must have a minimum section of 2.5 mm².
