SAFETY PRECAUTIONS

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 terminal

(located inside the reconnect input access doors).

SELECT SUITABLE LOCATION

Place the welder where clean cooling air can circulate
in through the rear louvers and out through the side
and front louvers. 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 fil-
ters. Failure to observe these precautions can result in
excessive operating temperatures and nuisance shut-
downs.

The Power Wave may be used outdoors. Power Wave
power sources carry an IP23 enclosure rating. They
are rated for use in damp, dirty environments subject
to occasional falling water such as rain. However, the
best practice is to keep the machine in a dry, sheltered
area, since a wet environment speeds corrosion of
parts. Do not place the machine in puddles or other-
wise submerge parts of the machine in water. This
may cause improper operation and is a possible safe-
ty hazard.

STACKING

Power Wave machines cannot be stacked.

TILTING

Each machine must be placed on a secure, level sur-
face. The machine may topple over if this procedure
is not followed.

LIFTING

Lift the machine by the lift bail only. Do not attempt to
lift the machine by the push handle.

HIGH FREQUENCY PRECAUTIONS

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 CONNECTIONS

Be sure the voltage, phase, and frequency of the input
power is as specified on the rating plate, located on
the rear of the machine. See Figure A.1 for the loca-
tion of the rating plate.

WARNING

1. RATING PLATE
2. RECONNECT/INPUT ACCESS DOOR
3. INPUT CORD ACCESS HOLE

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.

Use a three-phase supply line. The Power Wave has
a 1.375” (35mm) access hole for the input cord, but
the input cord is not supplied.
