SECTION 1 – SAFETY PRECAUTIONS – READ BEFORE
USING
1-1. Symbol Usage
safety_ihom 5/98
Means Warning! Watch Out! There are possible hazards
with this procedure! The possible hazards are shown in
the adjoining symbols.
Y Marks a special safety message.
. Means “Note”; not safety related.
This group of symbols means Warning! Watch Out! possible
ELECTRIC SHOCK, MOVING PARTS, and HOT PARTS hazards.
Consult symbols and related instructions below for necessary actions
to avoid the hazards.
1-2. Induction Heating Hazards
Y The symbols shown below are used throughout this manual to
call attention to and identify possible hazards. When you see
the symbol, watch out, and follow the related instructions to
avoid the hazard. The safety information given below is only
a summary of the more complete safety information found in
the Safety Standards listed in Section 1-4. Read and follow all
Safety Standards.
Y Only qualified persons should install, operate, maintain, and
repair this unit.
Y During operation, keep everybody, especially children, away.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks
or severe burns. The power circuit and output bus
bars or connections are electrically live whenever
the output is on. The input power circuit and machine
internal circuits are also live when power is on. Incorrectly installed or
improperly grounded equipment is a hazard.
D Do not touch live electrical parts.
D Enclose any connecting bus bars and coolant fittings to prevent
unintentional contact.
D Wear dry, hole-free insulating gloves and body protection.
D Insulate yourself from work and ground using dry insulating mats or
covers big enough to prevent any physical contact with the work or
ground.
D Disconnect input power before installing or servicing this equip-
ment. Lockout/tagout input power according to OSHA 29 CFR
1910.147 (see Safety Standards).
D Use only nonconductive coolant hoses with a minimum length of 18
inches (457 mm) to provide isolation.
D Properly install and ground this equipment according to its Owner’s
Manual and national, state, and local codes.
D Always verify the supply ground – check and be sure that input pow-
er cord ground wire is properly connected to ground terminal in
disconnect box or that cord plug is connected to a properly
grounded receptacle outlet.
D When making input connections, attach proper grounding
conductor first – double-check connections.
D Frequently inspect input power cord for damage or bare wiring – re-
place cord immediately if damaged – bare wiring can kill.
D Turn off all equipment when not in use.
D Do not use worn, damaged, undersized, or poorly spliced cables.
D Do not drape cables over your body.
D Do not touch power circuit if you are in contact with the work,
ground, or another power circuit from a different machine.
D Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
D Wear a safety harness if working above floor level.
D Keep all panels and covers securely in place.
SIGNIFICANT DC VOLTAGE exists after removal of
input power on inverters.
D Turn Off inverter, disconnect input power, and discharge input
capacitors according to instructions in Maintenance Section before
touching any internal parts.
INDUCTION HEATING can cause burns.
D Hot parts and equipment can injure.
D Do not touch or handle induction head/coil
during operation.
D Do not touch hot parts bare-handed.
D Allow cooling period before handling parts or equipment.
D Keep metal jewelry and other metal personal items away from
head/coil during operation.
FIRE OR EXPLOSION hazard.
D Do not overheat parts and adhesive.
D Watch for fire; keep extinguisher nearby.
D Keep flammables away from work area.
D Do not locate unit on, over, or near combustible surfaces.
D Do not install unit near flammables.
D Do not operate unit in explosive atmosphere.
Induction Heating of certain materials, adhesives,
and fluxes can produce fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
FUMES AND GASES can be hazardous.
D Keep your head out of the fumes. Do not breathe the fumes.
D If inside, ventilate the area and/or use exhaust to remove fumes
and gases.
D If ventilation is poor, use an approved air-supplied respirator.
D Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instruction for adhesives, fluxes, metals,
consumables, coatings, cleaners, and degreasers.
D Work in a confined space only if it is well ventilated, or while wearing
an air-supplied respirator. Always have a trained watchperson
nearby. Fumes and gases from heating can displace air and lower
the oxygen level causing injury or death. Be sure the breathing air is
safe.
D Do not heat in locations near degreasing, cleaning, or spraying op-
erations. The heat can react with vapors to form highly toxic and
irritating gases.
D Do not overheat coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the
heated area, the area is well ventilated, and if necessary, while
wearing an air-supplied respirator. The coatings and any metals
containing these elements can give off toxic fumes if overheated.
See coating MSDS for temperature information.
