3.1 TECHNICAL DATA
NOTE: here below data may differ from
the data on the technical table on the unit.
Always refer to the technical data table on
the unit.
4.0 INSTALLATION OF THE
EQUIPMENT
Proper operation of the generator is ensu-
red by adequate installation. The assem-
bly of the inverter must be done by expert
people, following the instructions and in
full respect of the safety standards.

BEFORE ATTEMPTING ANY ELECTRI-
CAL CONNECTION CHECK THE DATA
PLATE AND MAKE SURE THAT THE IN-
PUT VOLTAGE AND THE FREQUENCY
ARE THE SAME OF THE MAINS OUTLET
TO BE USED.
EARTHING
- To protect users the welding machi-
nes must be connected properly to the
earth (ground) system (INTERNATIONAL
SAFETY REGULATIONS).
- It is indispensable to earth (ground)
the machine properly with the yellow-
green conductor of the power supply ca-
ble, in order to avoid discharges due to
accidental contacts with earthed objects.
- The chassis (that is conductive) is
electrically connected to the earth con-
ductor. Failure to earth the equipment
correctly can cause electric shocks dan-
gerous to the users.

Do not use the generator with input ca-
bles’ extensions longer than 10m and
thinner than 2.5mm². Remember to keep
them layed and not wound or entangled.
Do not use the welder with the side panels
partially or completely removed in order
to avoid accidental contacts with inner
live parts.
