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 maxi-
mum 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.
-------------------------------------------------------------
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.
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.

SAFETY PRECAUTIONS
Read this entire installation section before you
start installation.
ELECTRIC SHOCK can kill.
• Only qualified personnel
should perform this installa-
tion.
• 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 sys-
tem 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.
-------------------------------------------------------------
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 impro per 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® over combustible
surfaces. Where there is a combustible surface direct-
ly under stationary or fixed electrical equipment, that
surface shall be covered with a steel plate at least
.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 bottom. 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 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 cir-
cuit 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.
