SAFETY PRECAUTIONS
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.
•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
Place the welder where clean cooling air can freely circulate in through the rear louvers and out through the case sides and bottom. Dirt, dust, or any foreign material that can be drawn into the welder should be kept at a minimum. Using filters on the air intake to prevent dirt from building up restricts air flow. Do not use such filters. Failure to observe these precau- tions can result in excessive operating temperatures and nuisance shutdowns.
This machine (above code 10500 only) is 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 prop- erly 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, locat- ed on the back of the Control PC board enclosure.
STACKING
Power Wave machines can be stacked to a maximum of 3 high. 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.
ENVIRONMENTAL PROTECTION
The Power Wave power source is rated IP21S and 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.
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.
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
If possible, locate the Power Wave away from radio controlled machinery. 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 electri- cal 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.
