made according to current standards. It is necessary to check this fundamental safety requirement. In the event of
doubt, have the electrical system checked by qualified personnel.
 The electrical system must be suitable for the maximum power absorption of the device, as indicated on the label
and in the manual, checking in particular that the section of the cables is suitable for that level of power absorp-
tion.
 For the main power supply of the device from the electricity mains:
- do not use adapters, multiple sockets or extensions;
- use a multiple pole switch with at least a 3 mm gap between the contacts (overvoltage category III), as envis-
aged by the present safety standards.
 Do not touch the device with wet or damp body parts and/or in bare feet.
 Do not pull the electric cables.
