General information
Check the grid characteristics against the
data indicated on the plate.
The identification plate bearing the
technical data, serial number and brand
name is visibly positioned on the appliance.
Do not remove this plate for any reason.
Perform the ground connection using a wire
that is 20 mm longer than the other wires.
The appliance can work in the following
modes:
•
220-240 V 1N
~
3 x 1.5 mm²
three-core cable.
Fixed connection
Fit the power line with an all-pole
disconnection switch, with a clearance
between its contacts that allows the
complete disconnection as per the
overvoltage category III, in compliance
with the installation regulations.
Connection with plug and socket
Make sure that the plug and socket are of
the same type. Avoid using adapters, gang
sockets or extensions as these could cause
overheating and a risk of burns.

personnel.
• Use personal protective equipment.
• The appliance must be connected to
earth in compliance with electrical
system safety standards.
• Disconnect the mains supply.
• Do not pull the cable to remove the
plug.
• Use cables withstanding a temperature
of at least 90 °C.
• The tightening torque of the screws of
the terminal board conductors must be
1.5 - 2 Nm.
The values indicated above refer
to the cross-section of the internal
conductor.
The aforementioned power cables
are sized taking into account the
coincidence factor (in compliance
with standard EN 60335-2-6).
