INSTALLATION
Make sure that the supply voltage is either 115 volts and a
minimum of 30 amp service or 230 volt and a minimum of 20
amp service. When mounting a plug, make sure it has an
adequate
capa
city, and that the "yellow/green conductor"
of the power
supply cable is connected to the ground or
“earth” terminal. The blue and brown wires need to be
connected to each of the other pins on the plug.
WARNING
Only skilled personnel should install the machine. All
connections must be carried out according to current
regulations.
See complete listing of safety messages at the beginning of
this manual.
The machine must be installed by qualified personnel.
All connections must be made in compliance with
current safety standards and full observance of safety
regulations (see CEI 26-23 - IEC-TS 62081).
Connect the air supply to the fitting B .
• If the system air contains a considerable amount
of
moisture and oil, it is best to use a drying filter to
avoid
excessive oxidation and wear of the consumer
parts,
damaging the torch and reducing the cutting
speed
and
quality
.
If the air supply comes from a pressure regulator of a
com
pressor or centralized system, the regulator must be set
to
an output pressure of no more than 8 bar (0.8 Mpa) or
116 PSI. If
the
air supply comes from a compressed air
cylinder, the
cylin
der must be equipped with a pressure
regulator. Never connect a compressed air cylinder
directly to the r
egu
lator on the machine! The pressure
could exceed
the capacity of the regulator, which might
explode!
1)
Connect the power cord A : the yellow-green cable
wir
e
must be connected to an efficient grounding
terminal of the plug. The remaining brown and blue
wires must be connected to the supply voltage.
2) Amperage requirements
• 230V 20 amp service.
• 115V 30 amp service.
3) The absorbed current I
1
may be determined a l s o by
reading the technical specifications shown on the
machine under the available supply voltage
U
1
.
4) Any extension cords must be sized appropriately for
current
I, but are not recommended.
