* Pressure regulator F1:
is located on the rear of the
machine; allows the compressed air pressure to be adju-
sted so as to take it to the value most suitable for cutting,
and filters the air from any impurity (e.g. humidity).
* A1: Centralised coupling.
The cable bundle of the torch is connected to this socket.
* A2: Ground cable socket.

5.0 TRANSPORT - UNLOADING
See “1.7 Attention: method of lifting“
Never underestimate the weight of the equipment,
(see technical specifications).
Never make the cargo pass or leave it suspended
over people or things.
Neither let the equipment or the single unit fall,
nor put it down with force.
6.0 INSTALLATION
Choose an adequate installation area by following
the criteria provided in Section "1.0 SAFETY" and
“2.0 ELECTROMAGNETIC COMPATIBILITY (EMC)”.
Do not position the power source and the equip-
ment on surfaces with inclination exceeding 10°
with respect to the horizontal plane. Protect the
installation from heavy rain and sun.
7.0 CONNECTION
7.1 Mains supply voltage
The generator is pre-set for 400V ~ mains voltage, for
delivery.
The equipment is guaranteed to operate for voltages
ranging ±10% above or below the nominal value;
(e.g.: NomV 400V ~ the working voltage ranges from
360V~ to 440V~).
CAUTION: to avoid damaging people or the instal-
lation, you need to control the selected mains volt-
age and the fuses BEFORE connecting the machine
to the mains. Furthermore, you need to make sure
that the cable is connected to a socket fitted with
an earth contact.
7.1.1 Selection of the mains voltage
CAUTION: before carrying out any operation
inside the generator, physically disconnect the
machinery from the mains electricity supply, by
removing the plug.
The voltage of the network should only be modified by qualified
personnel and while the machine is disconnected from the
power source, by simply removing the lateral panel and cor-
rectly positioning the connections onto the terminal box (fig. 4).
Fig. 4 Voltage change terminal box configuration.
For connection to mains 230Vac, the power supply
cable must be replaced using the kit code
73.11.008.
