Upon receiving the system:
• Remove the welding generator and all relevant accessories-
components from their packaging.
• Check that the weld machine is in good condition, if not report
any problems immediately to the seller-distributor.
• Make sure all ventilation grilles are open and that no foreign
bodies are blocking the air circulation.
Installation
The installation site for the system must be carefully chosen
in order to ensure its satisfactory and safe use. The user is re-
sponsible for the installation and use of the system in accord-
ance with the producer’s instructions contained in this manual.
Before installing the system the user must take into consider-
ation the potential electromagnetic problems in the work area.
In particular, we suggest that you should avoid installing the
system close to:
• Signalling, control and telephone cables.
• Radio and television transmitters and receivers.
• Computers and control and measurement instruments.
• Security and protection instruments.
Persons fitted with pace-makers, hearing aids and similar
equipment must consult their doctor before going near a ma-
chine in operation. The environment in which the equipment
is installed must be suitable for the casing’s protection level.
This system is cooled by means of the forced circulation of air,
and must therefore be placed in such a way that the air may
be easily sucked in and expelled through the apertures made
in the frame.
The welding unit is characterised by the following levels:
• Protection level IP 23 S indicates that the equipment can be
used both indoors and outdoors.
• Use class “S” means that the equipment can be used in con-
ditions subject to heightened electrical shock.
Connection to the electrical supply
Connection of the machine to the user line (electrical cur-
rent) must be performed by qualified personnel.
Before connecting the welding machine to the mains pow-
er supply, make sure that rated voltage and frequency cor-
respond to those provided by the mains power supply and
that the welding machine’s power switch is turned to “O”.
The four-pole cable supplied with the system must be used
for the connection to the mains power supply. This cable is
made up of:
• Three conductors that are used to connect the machine to
the power supply.
• The fourth, which is YELLOW-GREEN, is used to form the
“GROUND” connection.
Connect a suitable load of normalised plug (3p+t) to the
power cable and provide for an electrical socket complete
with fuses or an automatic switch. The ground terminal
must be connected to the ground conducting wire (YEL-
LOW-GREEN) of the supply.
Table 2 shows the capacity values that are recommended for
fuses in the line with delays.
NOTE: Any extensions to the power cable must be of a suita-
ble diameter, and absolutely not of a smaller diameter than the
special cable supplied with the machine.
