Other types of connection
The cable provided is not suitable for the following
types of installation.
If the mains supply corresponds with one of the
following:
Voltage and mains frequency
400V 3 - N ~ 50 Hz
400V 2 - N ~ 50 Hz
230V 3 ~ 50 Hz
230V 2 + 2 - N ~ 50 Hz
proceed as follows:
1. Use a suitable supply cable, H05RR-F or higher,
with the right dimensions (cable section: 1.5 mm).
2. To open the terminal board, insert a screwdriver
into the side tabs of the cover (see Terminal board
picture).
3. Loosen the cable clamp screw and the terminal
board screws according to the type of connection
required and position the connection supports as
shown in the following table and diagrams.
4. Position the wires according to the following table
and diagrams and connect the appliance by
tightening all the screws for the springs as much as
possible.

5. Secure the power supply cable by fastening the
clamp screw then put the cover back on.
Connecting the supply cable to the mains
If the appliance is being connected directly to the mains
an omnipolar circuit-breaker must be installed with a
minimum opening of 3 mm between contacts.
The installer must ensure that the correct electrical
connection has been made and that it is compliant with
safety regulations.
Before connecting to the power supply, make sure that:
The appliance is earthed and the plug is compliant
with the law.
The socket can withstand the maximum power of the
appliance, which is indicated on the attached data
plate.
The voltage is in the range between the values
indicated on the data plate.
The socket is compatible with the plug of the
appliance. If the socket is incompatible with the plug,
ask an authorised technician to replace it. Do not use
extension cords or multiple sockets.
Once the appliance has been installed, the power
supply cable and the electrical socket must be easily
accessible.
The cable must not be bent or compressed.
The cable must be checked regularly and replaced by
authorised technicians only.
The manufacturer declines any liability should these
safety measures not be observed.
