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 working 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.
LOCATION
Even though the machine is designed to operate under a wide variety of environmental conditions, for maximum reliability and long life the machine should be located in a clean, dry place where there is free cir- culation of clean air in through the front and out the back of the machine. Dirt and dust that can be drawn into the machine should be kept to a minimum. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdown of the machine.
The case front incorporates a recessed control panel which protects the controls and minimizes the possi- bilities of accidental contact. This cover panel can be flipped open to permit access to the enclosed control section.
The individual case sides are removable for easy access for internal service or inspection.
The case rear is equipped with a removable cover plate, permitting easy access to the input panel.
The total enclosure, designed to permit outdoor operation, resists dust, salt, rain, humidity, and high and low temperature extremes.
The machine uses a 38” (965mm) long base. The low profile case facilitates installation of the machine under a workbench and stacking the machines two high to conserve floor space.
A permanent lifting eye is located at the top of the machine and is positioned so that it acts as nearly as possible through the center of gravity. This lift eye fits under the case of the second machine without interference when stacking.
STACKING
WARNING
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 adequate lifting capacity.
•Be sure machine is stable when lifting.
•Do not stack more than two high.
•Do not stack the
Two
1.Make sure the first or bottom unit is setting on a level, well- supported surface.
2.The units must be stacked with their fronts flush, making sure the two holes in the base rails of the top unit are over the two pins located on top of the bottom unit.
INPUT WIRING
Be sure the voltage, phase and frequency of the input power is as specified on the welder nameplate.
Dual voltage (e.g. 230/460) models are shipped connected for the highest voltage. To change the connection, see the connec- tion diagram pasted to the inside of the access panel in the case back.
Have a qualified electrician remove the rear access panel and connect 3 phase AC power to terminals L1, L2 and L3 of the
input panel in accordance with the U.S. National Electrical Code, all local codes and the wiring diagram located inside the machine.
The welder frame must be grounded. A stud marked with the
symbol 
located inside the machine near the input panel is provided for this purpose. See the U.S. National Electrical Code for details on proper grounding methods. (See Technical Specifications)
