Lincoln Electric IM998 INVERTER ARC 120 - Manual (Page 11)

A-2 INSTALLATION
INVERTER ARC™ 120
A-2
Read entire installation section before starting
installation.
SAFETY PRECAUTIONS
ELECTRIC SHOCK can kill.
• Only qualified personnel should per-
form this installation.
• Disconnect input power by removing
plug from receptacle before working
inside INVERTER ARC™ 120. Allow
machine to sit for 5 minutes mini-
mum to allow the power capacitors
to discharge before working inside
this equipment.
•
Insulate yourself from the work and ground.
•
Always wear dry insulating gloves.
• Always connect the INVERTER ARC™ 120 to a
power supply grounded according to the National
Electrical Code and local codes.

SELECT SUITABLE LOCATION
This machine can operate in harsh environments.
However, it is important that simple preventative
measures are followed to assure long life and reliable
operation:
• This machine must be located where there is free
circulation of clean air without restrictions for air
movement to and from the air vents. Do not cover
the machine with paper, cloth or rags when switched
on.
• Dirt and dust that can be drawn into the machine
should be kept to a minimum.
• This machine has a protection rating of IP21S.
Keep it dry and do not place it on wet ground or in
puddles. Do not use in wet or damp locations. Store
indoors.
• Locate the machine away from radio controlled
machinery. Normal operation may adversely affect
the operation of nearby radio controlled machinery,
which may result in injury or equipment damage.
Read the section on electromagnetic compatibility in
this manual.
• Do not operate in areas with an ambient tempera-
ture greater than 40°C.
STACKING
The INVERTER ARC™ 120 cannot be stacked.
TILTING
Place the machine directly on a secure, level surface.
Do not place or operate this machine on a surface
with an incline greater than 15° from horizontal. The
machine may topple over if this procedure is not fol-
lowed.
INPUT CONNECTIONS
GROUND CONNECTION
The frame of the welder must be ground-
ed. A ground terminal marked with the
symbol is located on the under panel for
this purpose. See your local and national
electrical codes for proper grounding
methods.
A grounding conductor is supplied in the input
cord, it is important that the supply receptacle
ground is connected.
• The welding power source supply cable is pro-
vided with a green or yellow/green wire that must
ALWAYS be earthed. This green or yellow/green
wire must NEVER be used with other voltage
conductors.
• Only install plugs that conform with safety regu-
lations.

WARNING
WARNING
INPUT POWER CONNECTION
Check the input voltage, phase, and frequency sup-
plied to this machine before turning it on. The allow-
able input voltage is indicated in the technical specifi-
cation section of this manual and on the rating plate of
the machine. Be sure that the machine is grounded.
Make sure the power available at the input connection
is adequate for normal operation of the machine. The
fuse rating and cable sizes are both indicated in the
technical specification section of this manual.
Fuse the input circuit with time delay fuses marked “D”
or delay type
(1) circuit breakers. Using fuses or circuit
breakers smaller than recommended may result in
“nuisance” shut-offs from welder inrush currents even
if not welding at high currents.
(1) Also called “inverse time” or “thermal/magnetic” circuit breakers.
These circuit breakers have a delay in tripping action that
decreases as the magnitude of the current increases.
The INVERTER ARC™ 120 is recommended for use
on an individual branch circuit.
