5.6 Electrical connections
The unit’s connection to the power supply must be made in compliance with laws and prescriptions in force in the place of
installation, after having consulted the electrical diagram supplied with the plant.
The power input voltage must not surpass the tolerance limits shown on the electrical schematic, even momentarily; the
frequency and number of phases must comply with the indications on the unit’s data plate.
Unless otherwise specified, the frequency tolerance is +/-1% of the nominal value (+/-2% for short periods).
Voltage must be supplied between phase and neutral and the neutral conductor must be connected to earth in the factory
substation (TN system to IEC 364) or by the electricity company (TT system to IEC 364).
The positions of the phase conductor and the neutral conductor must not be switched.
For the electrical power supply:
1. Connect the unit (terminal in the electrical panel) to the electrical earthing system of the building.
2. Ensure automatic suspension of the power supply in the event of an insulation fault (protection against indirect
contact in compliance with the prescriptions of IEC 364) by means of a residual current device (the nominal trip
current of which should normally be set to 0.03 A).
3. Make sure the level of protection against indirect contact at the source of the power feeding cable is equivalent at
least to IP2X or IPXXB.
4. At the start of the power feeding cable or the power cable supplied with the unit install a device that protects the
cable from overcurrents (short circuits) (refer to the indications in the electrical schematic).
Install protection devices that limit the short circuit current to 17 kA peak in correspondence with the rated breaking
capacity if the short-circuit current in the point of installation is greater than an effective value of 10 kA.
5. Use connectors rated for the maximum required voltage at the maximum operating ambient temperature,
according to the chosen installation type (see the indications on the electrical schematic).
Indications on the electrical schematic:
1. maximum permissible size of the fuse type gG.
In general, fuses can be replaced by an automatic circuit breaker adjusted in relation to the machine maximum
current input (consult the manufacturer if necessary).
2. section and type of power cable (if not already supplied):
A installation: insulated conductors, multicore cable in a cable duct, installed overhead or fixed to a masonry
structure (type C in compliance with IEC 364-5-523 1983) or without any other cables in contact;
B cable type: copper conductors, 70 °C / 158 °F PVC insulation (unless otherwise specified) or 90 °C / 194 °F
EPR insulation.
