5.8 Electrical connections
To know the installed electrical power refer to the motor rating plate (technical data sheet).
The electrical connection operations must be performed by specialised, suitably
trained personnel.
Before making the electrical connections, make sure the electricity supply has been
disconnected so there is no voltage present.
The device must always be protected from dangers of indirect contact and dangers of
overload and overcurrent. Prepare adequate protections during installation, referring
to the technical characteristics of the product.
The electricity supply to the electrospindle MUST be through an inverter.
For the electric supply use a cable with cross-section adequate to the power installed at three
poles + earth. Before connecting the wires to the terminal board of the panel carry out the following
instructions:
„
check that the power supply matches that on the motor rating plate;
„
verify the condition of the conductors and the presence of the earth conductor;
„
verify that the absorption matches that on the motor rating plate.
To prevent any damage to the motor caused by overvoltages or rapid voltage changes, you are
required to test the power connections, which must be carried out while the entire system is
running, which checks the following conditions:
„
voltage surge measurement between one phase and another <1000 V;
„
phase voltage rise time measurement >200 ns.
Power supply distribution must comply with the voltage limits established by the
manufacturer. Check the values while the entire system is running.
