EARTHING
It is essential to earth the unit.
To this purpose, it is necessary to connect to an efficient earthing system the terminals marked with the symbols (
placed on the line-receiving terminal box. The earthing system should comply with the law in force.
SPECIFIC WARNINGS
The electrical safety of this unit is assured only when it is correctly connected to an efficient earthing system as stated
in the electrical safety regulations in force; the Manufacturer declines any responsibility for the non-compliance with
these safety regulations.
It is necessary to verify this fundamental safety requisite and, in case of doubt, ask for an accurate testing of the system by
professionally qualified personnel.
The Manufacturer cannot be deemed responsible for any damages caused by the lack of unit earthing.

POWER SUPPLY CABLE
The unit is supplied fitted for the following voltages:
The flexible cable for power supply connection should not have characteristics lower than the rubber insulation type
H07RN-F. The cable should be inserted through the cable clamp and firmly fastened. Furthermore, the supply voltage with
the unit functioning should not go outside the value of the nominal tension ±10%.
To have access to the terminal box in order to connect the unit to a supply network having different characteristics from those
provided for, or to replace the supply cable, you need to:
- remove the front panel (top or top + cabinet) or
- remove the appropriate panel on the left side (cooker with electric oven)
