SHIELDING
The selective shielding of other cables and equipment present
in the surrounding area may reduce the problems due to inter-
ference. The shielding of the entire welding installation can be
taken in consideration for special applications.

1.5 IP Protection rating

Casing protection rating in compliance with EN 60529:
IP21S
- Casing protected against access to dangerous parts with fin-
gers and against solid foreign bodies with diameter greater
than/equal to 12.5 mm
- Casing protected against vertical drops of water.
Do not use outdoors in the event of rain.
- Casing protected against harmful effects of water seeping in
when the moving parts of the equipment are not operating.

2 INSTALLATION

The connection (series or parallel) of the genera-
tors is prohibited.

2.1 Lifting, transport and unloading procedures

Do not underestimate the weight of the equip-
ment: see technical specifications.
Do not move or position the suspended load
above persons or things.
Do not drop or exert undue pressure on the sy-
stem or individual unit.
The use of the handle for purposes of lifting is
prohibited.
Use the following equipment for lifting:
- a forklift truck, paying maximum attention during movement
to prevent the power source tipping over.
The manufacturer accepts no liability if the above prescrip-
tion is not duly observed and complied with at all times.

2.2 Positioning the power source

Keep to the following rules:
- Easy access to the equipment controls and connections
must be provided.
- Do not position the equipment in reduced spaces.
- Do not place the generator on surfaces with inclination
exceeding 10° with respect to the horizontal plane.
- Position the power source in a dry, clean and suitably venti-
lated place.
- Protect the system against driving rain and the sun.

2.3 Positioning of bottles

- Compressed gas cylinders are dangerous; consult the supplier
before handling them.
Protect them from:
- direct exposure to sun rays;
- flames;
- sudden changes in temperature;
- very low temperatures.
Compressed gas cylinders must be fixed to the walls or to other
supports, in order to prevent them from falling.

2.4 Connection

2.4.1 Mains voltage

CAUTION: to prevent injury to persons or damage
to the system, the selected mains voltage and fuses
must be checked BEFORE connecting the machine to
the mains. Also check that the cable is connected to
a socket provided with earth contact.
Operation of the equipment is guaranteed for voltage
tolerances of up to +10-20% with respect to the rated
value (example: with Vnom 400V the working voltage
is between 320V and 440V).
Before shipment, the power source is pre-set for mains
voltage at 400V.

2.4.2 Selecting the mains voltage

CAUTION: when carrying out any operation
inside the power source, physically disconnect the
system from the mains by unplugging it.
The mains voltage can be altered only by qualified personnel
and with the machine disconnected from the mains, by remo-
ving the side panel and correctly positioning the connections on
the terminal block (fig.1).
