SAFETY PRECAUTIONS

Read this entire installation section before you

start installation.

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.

WARNING

ELECTRIC SHOCK can kill.

•Only qualified personnel should per- form 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 subjected to falling water, nor should any parts of it be submerged in water. Doing so may cause improper operation as well as pose a safety hazard. The best practice is to keep the machine in a dry, sheltered area.

Do not mount the Power Wave 455/STT over combustible sur- faces. Where there is a combustible surface directly under sta- tionary or fixed electrical equipment, that surface shall be cov- ered with a steel plate atleast .060" (1.6mm) thick, which shall extend not less than 5.90" (150mm) beyond the equipment on all sides.

Place the welder where clean cooling air can freely circulate in through the rear louvers and out through the case sides and bot- tom. Dirt, dust, or any foreign material 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 tem- peratures 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 out- put 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., con- nect 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)

LIMIT ON STACKING

CAUTION

FALLING EQUIPMENT can cause injury.

•Do not lift this machine using lift bale if it is equipped with a heavy accessory such as trailer or gas

cylinder.

•Lift only with equipment of ade- quate lifting capacity.

•Be sure machine is stable when lifting.

•Do not stack more than three high.

•Do not stack the CV-400 on top of any other machine.

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

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 diagram 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. Connect L1, L2, L3 and ground according to the Input Supply Connection Diagram decal located on the inside of the input access door or refer to Figure A.1 on the following page.
