2 - INSTRUCTIONS FOR INSTALLATION AND MAINTENANCE
2.2 - Electrical connection
Connection to the power grid
• The connection to the power supply grid must be performed in com-
pliance with the international, national and local regulations in force.
• Before connecting the oven make sure that the voltage and the fre-
back panel.
It is reminded that a variation of the maximum voltage of ±10 % is ad-
mitted.
• The oven must be permanently connected to the power grid with an
H07RN-F type cable (heavy duty poly-chloroprene rubber) or or higher
with the section of the leading wires based on the maximum charge ab-
sorbed (see paragraph 1.4).
• Between the oven and the power grid there must be a general omni-
polar switch with a contact distance of at least 3mm, having a capacity
close to the load and equipped with the appropriate protection devices.
• It is necessary to provide the appropriate high-sensitivity automatic dif-
ferential 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 the immediate proximity of the
oven itself so that its operators can 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 para-
graph 1.4).
2.3 Grounding
• The yellow/green power supply cable must be secured in the clamp
• The oven must be included in an equipotential system the connec-
tion of which will have to be performed using a cable with a minimum
section of 10 mm

connected to the clamp (A - Fig. 5) marked with the
symbol placed on the backside of the oven.
• It is recommended to connect the supply cable to the oven inside a
metal tube adequately freed of shard edges or in a tube made of suita-
ble rigid plastic material.
2.4 - Water supply connection

before the water circuit.
• The admitted water supply pressure is of a mi-
nimum of 200 kPa, maximum of 300 kPa.
