CONNECTIONS TO THE MAINS AND CONNECTION PLANTS MUST COMPLY WITH THE LEGAL PROVI- SIONS IN FORCE IN THE COUNTRY OF INSTALLATION AND MUST BE PERFORMED BY QUALIFIED PERSONNEL AUTHORISED BY THE MANUFACTURER. n order to avoid any risks, damaged power supply cables must be replaced by the Manufacturer, by an approved technical support centre, or in any case by an individual with similar qualifications. Before connect- ing the device to the mains:
- read the safety instructions provided at the beginning of the installation manual;
- make sure the mains voltage and frequency correspond to those indicated in the device serial number A rated volt- age variation of +/-10% is accepted.
THE DEVICE MUST BE CONNECTED TO AN EFFICIENT GROUND SOCKET. THE DEVICE MUST INCLUDE AN EQUIPOTENTIAL SYSTEM COMPLIANT TO THE LEGAL PROVISIONS IN FORCE (YELLOW GREEN CONDUCTOR WITH A MAXIMUM SECTION OF 10 MMQ - CEI EN 60335-2-89 NORM). THIS CONNECTION MUST BE MADE BETWEEN THE VARIOUS DEVICES WITH THE TERMINAL MARKED WITH THE EQUIPOTENTIAL SYMBOL.
For mains connections, use a circuit breaker with manual reset high sensitivity (30 mA), with adequate power that permits com- plete cut-off in over voltage category III conditions, in order to protect the device against over voltages or short circuits.
For the sizing of the protection device, please refer to the technical data table at the end of the manual.
The single-phase appliances leave the factory with the power cable and an Unel plug already installed on the terminal block: it is not allowed to make any other type of electrical connection and no dimensional modification of the cable other than its length- ening, replacing it with one having the same characteristics as the original one (rubber type, section, etc.).
The three-phase appliances leave the factory with the power cable already installed on the terminal block: fit an electric plug (not supplied) of a type and capacity suitable for the maximum current absorbed by the phases of the appliance or make a direct connection to an electrical panel.
