SECTION 3:
INSTALLATION, OPERATION AND SETUP
G. The enclosure design of this power source meets the
requirements of IP23S as outlined in EN 60529. This
provides adequate protection against solid objects
(greater than 0.5" (12mm)), and direct protection
from vertical drops. Under no circumstances
should the unit be operated or connected in a micro
environment that will exceed the stated conditions.
For further information please refer to EN 60529.
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.
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
voltage. Too low a voltage may cause poor welding
performance. Too high a supply voltage will cause
components to overheat and possibly fail.
The Welding Power Source must be:
• Correctly installed, if necessary, by a qualified
electrician.
• Correctly earthed (electrically) in accordance with
local regulations.
• Connected to the correct size power point and fuse
as per the Specifications on page 3-2.
3.01 Environment
These units are designed for use in environments with
increased hazard of electric shock as outlined in EN
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 considerable 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 0° C to 40° C.
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 12" (300 mm) or more from
walls or similar that could restrict natural air flow
for cooling.
