5.1 CONNECTION TO ELECTRICAL POWER SUPPLY
We recommend not to connect the machine to the electrical power supply until it is not correctly placed in the
right place. Before connecting the machine to the electrical power supply, it is necessary to verify that the
electrical system corresponds to the following necessary power and safety requirements:
grounded equipotential electrical system
the electrical power system must be in conformity with CEI 64.8 (CENELEC HD 384, IEC364-4-41) rules
Automatic protection devices installed upstream respect to the machine; they have to be coordinated to
guarantee the automatic break according to above mentioned rules.
the tolerance of admissible voltage is +/-10%
Voltage and frequency for the motors are specified on the plates placed on them
Connect the power supply cable to R-S-T terminals: the electrical connection is done by three-phase plug (or
single-phase plug, depending on the panel). The cable for ground connection is yellow-green.
When voltage is applied to the electrical power supply, check that the spindles rotation direction is the one
written in the plate placed on the head (Black=Right; Red=Left).
If the rotation direction does not match the one impressed in the plate, please invert the connection cables to
three phase power supply.
For any information please see the electrical diagrams included in this manual.
THE CONNECTION OF THE MACHINE MUST BE CARRIED OUT BY QUALIFIED
TECHNICAL PERSONNEL
DO NOT tamper with the electrical system
Make sure that the voltage of the electric plug corresponds to that required by the machine
