CONNECTING THE COMPRESSOR TO THE ELECTRICAL POWER SUPPLY
The machine is connected to the electrical power network by the customer, at his own
expense and responsibility, using qualified personnel and in compliance with accident
prevention standard EN 60204
5.7.3.1
Ground connection
To protect the operator from electric shocks, the compressor must be grounded during use. The
ground connection must be carried out by a qualified technician or by a specialized service centre.
The ground connection on the compressor power supply cord must be connected only to the
terminal on the compressor itself.
Before replacing the plug of the power supply cord, make certain that the ground is connected.
5.7.3.2
Sizing the Power Supply Cable
Never use damaged cables. Always make certain that the cable is in good condition. Use only
cables with an adequate size to the compressor's maximum current absorption. If the cable is too
thin, there will be a drop in voltage, power loss and the unit will overheat. The cable section must
be proportioned to the cable length and to the ambient temperature of the room where the cables are
used. The values indicated below refer to an ambient temperature within 40°C:
Avoid all risks of electric discharges. Never use the compressor if the power supply
cord or extension cord are damaged. Check the electrical cables regularly. Never use
the compressor in dangerous environments where electrical discharges can occur.
Installation must be performed by a qualified technician.
