SECTION 3:
INSTALLATION, OPERATION AND SETUP
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
Thermal Arc advises that this equipment
be electrically connected by a qualified
electrician.
3.03 ELECTRICAL INPUT
CONNECTIONS
WARNING
ELECTRIC SHOCK can kill; SIGNIFICANT
DC VOLTAGE is present after removal of
input power.
DO NOT TOUCH live electrical parts.
SHUT DOWN welding power source, disconnect input
power employing lockout/tagging procedures. Lock-
out/tagging procedures consist of padlocking line
disconnect switch in open position, removing fuses
from fuse box, or shutting off and red-tagging circuit
breaker or other disconnecting device.
• Electrical Input Requirements
Operate the welding power source from a single-phase
50/60 Hz, AC power supply. The input voltage must
match one of the electrical input voltages shown on
the input data label on the unit nameplate. Contact the
local electric utility for information about the type of
electrical service available, how proper connections
should be made, and inspection required. The line
disconnect switch provides a safe and convenient
means to completely remove all electrical power
from the welding power supply whenever necessary
to inspect or service the unit.
Do not connect an input (BROWN or BLUE) conductor
to the ground terminal.
Do not connect the ground (GREEN or GREEN/
YELLOW) conductor to an input line terminal.
Refer to Figure 3-1:
1. Connect end of ground (GREEN or GREEN/
YELLOW) conductor to a suitable ground. Use
a grounding method that complies with all
applicable electrical codes.
3.01 ENVIRONMENT
These units are designed for use in environments
with increased hazard of electric shock. Examples
of environments with increased hazard of electric
shock are:
A. 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.
B. 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.
C. 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.
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 300mm 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
EN 60529. This provides adequate protection
against solid objects (greater than 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.
