4.3 Electrical wiring
Notes on safety for the electrical wiring
- The electrical wiring must be carried out with the electrical supply disconnected.
- Electrical wiring must be made in accordance with the regulations currently in force in the country of destina-
tion and by qualified personnel. Refer to the wiring diagrams.
DANGER - The manufacturer declines all responsibility for modifications or connections different from those shown in the
wiring diagrams.
- Check that the electrical supply of the burner corresponds to that shown on the identification label and in this
manual.
- The electrical safety of the device is obtained only when it is correctly connected to an efficient earthing sys-
tem, 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. Do not use the gas tubes as an
earthing system for electrical devices.
- 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
absorption.
- 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
envisaged 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.
Before carrying out any maintenance, cleaning or checking operations:
Disconnect the electrical supply from the burner by means of the main system switch.
