CONNECTIONS TO THE MAINS AND CONNECTION PLANTS MUST COMPLY WITH THE LEGAL PROVISIONS 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 those indicated in the device serial number plate. 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 complete cut-off in over voltage category III conditions, in order to protect the device against over voltages or short circuits.
Consider the following for protection device dimensioning:
Imax = 2,3 In (rated current)
Icc (short circuit current) = 4500A with a power source of 230V/1~/50Hz
Icc (short circuit current) = 6000A with a power source of 400V/3~/50Hz
5 and 8 tray machines (single-phase 230V/1~/50Hz ) are supplied with a power cable and a Unel plug installed on the terminal board: any other type of electric connection or any cable dimension modifications are prohibited. The cable can be extended by replacing it with one that has the same specifications as the original (rubber type, section, etc.).
12 and 16 tray machines (three-phase 400V/3~/50Hz) are supplied with a power cable installed on the terminal board: assemble an electric plug (not supplied) of a proper type and a capacity suited to the maximum absorbed current from the oven phases or make a direct connection to the electric panel.
