CONNECTION TO ENERGY SOURCES
4.2 ELECTRICAL CONNECTION
On the power supply line upstream of the appliance, a locking device must be installed that shuts off the
power whenever it is necessary to operate in safe conditions, such as:
• manual switch of suitable capacity, equipped with fuse valves
• circuit breaker with relevant thermal-magnetic and differential relays.
Obligation to exclude the power supply upstream of the appliance whenever it is necessary to operate
in safe conditions
Electrical connection should be performed in compliance with the IEC regulations, only by authorised and competent
per-sonnel. In the first instance, examine the data shown on the technical data table of this manual, on the serial
plate and on the electrical diagram. The envisaged connection is of the fixed type.
Ahead of each unit it is necessary to install an omnipolar main breaker, having a spacing among contacts of
at least 3mm; example:
- manual breaker of appropriate capacity, complete with fuse valves
- automatic breaker with respective magnetothermal relays.
Earthing
It is essential to earth the unit.To this purpose, it is necessary to connect to an effi cient earthing system the termi-
nals 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 effi cient 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 qualifi ed personnel.The Manufacturer cannot
be deemed responsible for any damages caused by the lack of unit earthing.
Never interrupt the earth wire (Yellow-Green).
Connections to various electrical distribution networks
The appliances are delivered to operate with the voltage indicated in the diagram below. Any other use is consid-
ered inappropriate and therefore dangerous.
It is absolutely forbidden to change and/or modify the wiring set by the manufacturer visible on the
product identification plate.
Connection of the wiring that is different from that indicated must be authorised by the manufacturer.
Electrical connection of the cable to the terminal block
Connect the power cable to the terminal block as described in: "Electrical connection attachment".
The diagram and the table (see "Technical Data") indicate possible connections in relation to the mains voltage.
