SECTION 1 − SAFETY PRECAUTIONS − READ BEFORE

USING

YWarning: Protect yourself and others from injury — read and follow these precautions.

1-1. Symbol Usage

safety_ihom 5/05

Means Warning! Watch Out! There are possible hazards with this procedure! The possible hazards are shown in the adjoining symbols.

YMarks 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

YThe 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 1-5. Read and follow all Safe- ty Standards.

YOnly qualified persons should install, operate, maintain, and repair this unit.

YDuring 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.

DDo not touch live electrical parts.

DEnclose any connecting bus bars and coolant fittings to prevent unintentional contact.

DWear dry, hole-free insulating gloves and body protection.

DInsulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact with the work or ground.

DAdditional safety precautions are required when any of the follow- ing electrically hazardous conditions are present: in damp locations or while wearing wet clothing; on metal structures such as floors, gratings, or scaffolds; when in cramped positions such as sitting, kneeling, or lying; or when there is a high risk of unavoidable or ac- cidental contact with the workpiece or ground. For these conditions, see ANSI Z49.1 listed in Safety Standards. And, do not work alone!

DDisconnect input power before installing or servicing this equip- ment. Lockout/tagout input power according to OSHA 29 CFR 1910.147 (see Safety Standards).

DUse only nonconductive coolant hoses with a minimum length of 18 inches (457 mm) to provide isolation.

DProperly install and ground this equipment according to its Owner’s Manual and national, state, and local codes.

DAlways 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.

DWhen making input connections, attach proper grounding conductor first − double-check connections.

DFrequently inspect input power cord for damage or bare wiring − re- place cord immediately if damaged − bare wiring can kill.

DTurn off all equipment when not in use.

DDo not use worn, damaged, undersized, or poorly spliced cables.

DDo not drape cables over your body.

DDo not touch power circuit if you are in contact with the work, ground, or another power circuit from a different machine.

DUse only well-maintained equipment. Repair or replace damaged parts at once. Maintain unit according to manual.

DWear a safety harness if working above floor level.

DKeep all panels and covers securely in place.

SIGNIFICANT DC VOLTAGE exists in inverter-type power sources after removal of input power.

DTurn Off inverter, disconnect input power, and discharge input capacitors according to instructions in Maintenance Section before touching any internal parts.

FUMES AND GASES can be hazardous.

Induction Heating of certain materials, adhesives, and fluxes can produce fumes and gases. Breathing these fumes and gases can be hazardous to your health.

DKeep your head out of the fumes. Do not breathe the fumes.

DIf inside, ventilate the area and/or use local forced ventilation to re- move fumes and gases.

DIf ventilation is poor, wear an approved air-supplied respirator.

DRead and understand the Material Safety Data Sheets (MSDSs) and the manufacturer’s instruction for adhesives, fluxes, metals, consumables, coatings, cleaners, and degreasers.

DWork in a confined space only if it is well ventilated, or while wearing an air-supplied respirator. Always have a trained watchperson near- by. Fumes and gases from heating can displace air and lower the oxygen level causing injury or death. Be sure the breathing air is safe.

DDo not heat in locations near degreasing, cleaning, or spraying oper- ations. The heat can react with vapors to form highly toxic and irritating gases.

DDo 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 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.
