this
entire installation section before you start installa-
tion.
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 work
ing on the equipment.
• Do not touch electrically hot parts.
• Always connect the POWER WAVE® 300C
grounding lug (located inside the reconnect input
access door) to a proper safety (Earth) ground.

SELECT SUITABLE LOCATION
The POWER WAVE
®
300C will operate in harsh environ-
ments. Even so, it is important that simple preventative
measures are followed in order to assure long life and reli-
able operation.
• The machine must be located where there is free circula-
tion of clean air such that air movement in the back, out
the sides and bottom will not be restricted.
• Dirt and dust that can be drawn into the machine should
be kept to a minimum. The use of air filters on the air
intake is not recommended because normal air flow may
be restricted. Failure to observe these precautions can
result in excessive operating temperatures and nuisance
shutdown.
• Keep machine dry. Shelter from rain and snow. Do not
place on wet ground or in puddles.
• Do not mount the POWER WAVE
®
300C over com-
bustible 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
.060” (1.6mm) thick, which shall extend not less than
5.90” (150mm) beyond the equipment on all sides.
WARNING
STACKING
The POWER WAVE
®
300C cannot be stacked.
TILTING
Place the machine directly on a secure, level surface or on
a recommended undercarriage. The machine may topple
over if this procedure is not followed.
INPUT AND GROUND CONNECTIONS
Only a qualified electrician should connect the POWER
WAVE
®
300C. Installation should be made in accordance
with the appropriate National Electrical Code, all local
codes and the information in this manual.
MACHINE GROUNDING
The frame of the welder must be grounded. A ground ter-
minal marked with a ground symbol is located next to the
input power connection block.
See your local and national electrical codes for proper
grounding methods.
HIGH FREQUENCY PROTECTION
The EMC classification of the POWER WAVE
®
300C is
Industrial, Scientific and Medical (ISM) group 2, class A.
The POWER WAVE
®
300C is for industrial use only. (See
Electromagnetic compatibility EMC Safety Section)
.
Locate the POWER WAVE
®
300C away from radio con-
trolled machinery. The normal operation of the POWER
WAVE
®
300C may adversely affect the operation of RF con-
trolled equipment, which may result in bodily injury or dam-
age to the equipment.
• Lift only with equipment of adequate
lifting capacity.
• Be sure machine is stable when lifting.
• Do not operate machine while suspend-
ed when lifting.
FALLING
EQUIPMENT can
cause injury.
