SAFETY PRECAUTIONS

Read this entire installation section before you

start installation.

WARNING

ELECTRIC SHOCK can kill.

•Only qualified personnel should perform this installation.

•Turn the input power OFF at the

disconnect switch or fuse box before working on this equipment. Turn off the input power to any other equipment connected to the welding system at the disconnect switch or fuse box before work- ing on the equipment.

•Do not touch electrically hot parts.

•Always connect the Power Wave grounding lug (located inside the reconnect input access door) to a proper safety (Earth) ground.

----------------------------------------------------------

SELECT SUITABLE LOCATION

Do not use Power Waves in outdoor environments. The Power Wave power source should not be subject- ed to falling water, nor should any parts of it be sub- merged in water. Doing so may cause improper opera- tion as well as pose a safety hazard. The best practice is to keep the machine in a dry, sheltered area.

Place the welder where clean cooling air can freely cir- culate in through the rear louvers and out through the case sides and bottom. Dirt, dust, or any foreign mater- ial that can be drawn into the welder should be kept at a minimum. Do not use air filters on the air intake because the air flow will be restricted. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdowns.

Machines above code 10500 are equipped with F.A.N. (fan as needed) circuitry. The fan runs whenever the output is enabled, whether under loaded or open circuit conditions. The fan also runs for a period of time (approximately 5 minutes) after the output is disabled, to ensure all components are properly cooled.

If desired, the F.A.N. feature can be disabled (causing the fan to run whenever the power source is on). To disable F.A.N., connect leads 444 and X3A together at the output of the solid state fan control relay, located on the back of the Control PC board enclosure. (See Wiring Diagram)

CAUTION

DO NOT MOUNT OVER COMBUSTIBLE SURFACES.

Where there is a combustible surface directly under stationary or fixed electrical equipment, that surface shall be covered with a steel plate at least

.06”(1.6mm) thick, which shall extend not less than 5.90”(150mm) beyond the equipment on all sides.

LIFTING

Lift the machine by the lift bail only. The lift bail is designed to lift the power source only. Do not attempt to lift the Power Wave with accessories attached to it.

STACKING

Power Wave machines can be stacked to a maximum of 3 high.

CAUTION

The bottom machine must always be placed on a firm, secure, level surface. There is a danger of machines toppling over if this precaution is not taken.

MACHINE GROUNDING

The frame of the welder must be grounded. A ground

terminal marked with the symbol is located inside the reconnect/input access door for this purpose. See your local and national electrical codes for proper grounding methods.

HIGH FREQUENCY PROTECTION

Locate the Power Wave away from radio controlled machinery.

CAUTION

The normal operation of the Power Wave may adversely affect the operation of RF controlled equipment, which may result in bodily injury or damage to the equipment.

INPUT CONNECTION

WARNING

Only a qualified electrician should connect the input leads to the Power Wave. Connections should be made in accordance with all local and national electrical codes and the connection dia- gram located on the inside of the reconnect/input access door of the machine. Failure to do so may result in bodily injury or death.

------------------------------------------------------------------------

Use a three-phase supply line. A 1.75 inch (45 mm) diameter access hole for the input supply is located on the upper left case back next to the input access door.
