SAFETY PRECAUTIONS Read
entire installation section before you start installa-
tion.
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 working on the equipment.
• Do not touch electrically hot parts.
• Always connect the Power Wave 455M/STT (CE)
grounding lug (located inside the reconnect input
access door) to a proper safety (Earth) ground.
----------------------------------------------------------
SELECT SUITABLE LOCATION
Do not use Power Wave 455M/STT (CE) in outdoor
environments. The Power Wave 455M/STT (CE) 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 safe-
ty hazard. The best practice is to keep the machine in
a dry, sheltered area.
Do not mount the Power Wave 455M/STT (CE) 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 1.6mm (.060") thick, which shall extend
not less than 150mm (5.90") beyond the equipment on
all sides.
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 mate-
rial 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 oper-
ating temperatures and nuisance shutdowns.
Machines are equipped with F.A.N. (fan as needed) cir-
cuitry. 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 min-
utes) after the output is disabled, to ensure all compo-
nents 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)
INSTALLATION
LIFTING
this
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.
FALLING
EQUIPMENT can
cause injury.
Do not stack the Power Wave 455M/STT (CE) on
top of any other machine.
------------------------------------------------------------------------
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
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.

WARNING
• Lift only with equipment of
adequate lifting capacity.
• Be sure machine is stable
when lifting.
• Do not lift this machine using
lift bail if it is equipped with a
heavy accessory such as trail-
er or gas cylinder.
• Do not lift machine if lift bail is
damaged.
• Do not operate machine while
suspended from lift bail.
