INSTALLATION/SETUP FABRICATOR 252i
Manual 0-5155 3-1 INSTALLATION/SETUP
3.01 Environment
This unit is designed for use in environments with
increased hazard of electric shock as outlined in IEC
60974.1. Additional safety precautions may be required
when using unit in an environment with increased hazard
of electric shock. Please refer to relevant local standards
for further information prior to using in such areas.
A. Examples of environments with increased hazard of
electric shock are:
1. In locations in which freedom of movement is
restricted, so that the operator is forced to perform
the work in a cramped (kneeling, sitting or lying)
position with physical contact with conductive
parts.
2. In locations which are fully or partially limited by
conductive elements, and in which there is a high
risk of unavoidable or accidental contact by the
operator.
3. In wet or damp hot locations where humidity
or perspiration considerably reduces the skin
resistance of the human body and the insulation
properties of accessories.
B. Environments with increased hazard of electric shock
do not include places where electrically conductive parts in
the near vicinity of the operator, which can cause increased
hazard, have been insulated.
3.02 Location
Be sure to locate the welder according to the following
guidelines:
A. In areas, free from moisture and dust.
B. Ambient temperature between 32° F to 104° F.
C. In areas, free from oil, steam and corrosive gases.
D. In areas, not subjected to abnormal vibration or shock.
E. In areas, not exposed to direct sunlight or rain.
F. Place at a distance of 1 foot or more from walls or
similar that could restrict natural air flow for cooling.
G. The enclosure design of this power source meets the
requirements of IP23S as outlined in IEC60529.
H. Precautions must be taken against the power source
toppling over. The power source must be located on
a suitable horizontal surface in the upright position
when in use.
SECTION 3: INSTALLATION OPERATION AND SETUP
WARNING
This equipment should be electrically
connected by a qualified electrician.
3.03 Ventilation
!
WARNING
Since the inhalation of welding fumes can
be harmful, ensure that the welding area is
effectively ventilated.
3.04 Mains Supply Voltage
Requirements
The Mains supply voltage
should be within ± 15% of the rated Mains supply volt-
age. Too low of a supply voltage may cause poor welding
performance or wirefeeder malfunction. Too high of a
supply voltage will cause components to overheat and
possibly fail.
WARNING
The Fabricator 252i must be electrically con-
nected by a qualified electrical trades-person.
Damage to the PCA (Power Control Assembly)
could occur if 276 VAC or higher is applied to
the Primary Power Cable.
