Three-phase static transformer-rectifier fre-
quency converter.
N°. Serial number, (that must be indicated on
any request regarding the equipment).
Drooping characteristic.
P.A.C. Suitable for plama cutting.
torch type Welding torch type which has to be used
with this equipment to correctly achieve a
safe system.
U0 Secondary open-circuit voltage (peak value).
X Duty cycle percentage.
The duty cycle expresses the percentage of
10 minutes during which the equipment may
run at a certain current I2 and U2 voltage
without overheating.
I2 Cutting current.
U2 Secondary voltage with I2 cutting current.
This voltage depends on the distance be-
tween nozzle and the workpiece. If this dis-
tance increases also the cutting voltage
increases and the duty cycle X% may de-
crease.
U1 Rated supply voltage.
3~ 50/60Hz 50- or 60-Hz three-phase power supply.
I1 max. This is the maximum value of the absorbed
current.
l1 eff. This is the maximum value of the actual cur-
rent absorbed, considering the duty cycle.
IP21 Degree of housing protection.
Degree 1 as the second digit means that this
device is not suitable for use outdoors.
This device is not suitable for use outdoors.

NOTES:
1-The device has been designed for use in environments
with a pollution rating of 3. (See IEC 60664).
2-This device complies with standard IEC 61000-3-12
provided that the system's maximum permitted im-
pedance Zmax is less than or equal to 98 mΩ (Item No
334) or 66 mΩ (Item No 336) or 22 mΩ (Item No 337) at
the interface point between the user's system and the
mains. The fitter or the device user are responsible for
connecting the device to a power supply with a maxi-
mum permitted system impedance Zmax less than or
equal to 98 mΩ (Item No 334) or 66 mΩ (Item No 336)
or 22 mΩ (Item No 337).

3.1 UNPACKING AND PLACEMENT

Use appropriate lifting and handling measures.
For Item No 337
The power source, including its wooden pallet, weighs
approximately 45 kg. Use appropriate lifting and han-
dling measures.
To remove the wooden pallet forming part of the pack-
aging:
• Remove the fastening straps
• Remove the cardboard packaging
Lift the power source with the aid of another person or a
fork lift. In the latter case, follow all the fork lift manufac-
turer's safety guidelines.
