TThe appliance must be connected to the electrical mains
with a double insulated three-core cable or equivalent with
appropriate cross-section.
For the connection to the mains power supply 2-pole switch
must be provided in the vicinity of the appliance. This switch
must have a contact opening distance of at least 3 mm, as
expected by applicable standards in force.
Ensure that the polarity between live and neutral wires is
maintained when connecting the appliance.
