3.4 ELECTRICAL CONNECTION - START UP
Electrical installation should be carried out by competent, qualified personnel.
The mains connection should be made using the terminal box.
Ensure that the mains supply corresponds with that of the machine, use cables of a section suitable for the power of the motor. For a supply tension of 400
V the minimum section recommended is 2.5 mm, including the earth wire.
For a mains supply of 230 V or a power rating greater than 15 A it will be necessary to increase the section of the connecting cables.
Connect the phase wires to the terminals R- S - T (L1 - L2 - L3) and the earth wire to the earth terminal.
On initial start-up check the direction of rotation, if it is incorrect then invert the two phase wires (for machines with 3 phase supply). Direction of rotation
of machines with single-phase supply is pre-determined during production .
On completion of the installation check that the terminal box is closed correctly and that the plug points are locked.
