SAFETY PRECAUTIONS
Read the entire installation section before starting
installation.
ELECTRIC SHOCK can kill.

Only qualified personnel
should perform this
installation.

Turn the input power OFF at
the main 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 main switch or fuse
box before working on the equipment.

Do not touch electrically
“Hot” parts.

Always connect the INVERTEC
®
grounding lug
(located at the rear of the case) to a proper safety
(Earth) ground. INVERTEC
®
is for use on a 4 wire
system with earthed neutral.
SELECT SUITABLE LOCATION
This 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 safety hazard. The best practice is to keep the
machine in a dry, sheltered area.
The bottom of machine must always be placed on a
firm, secure, level surface. There is a danger of the
machine toppling over if this precaution is not
taken.
Place the welder where clean cooling air can freely
circulate in through the back louvers and out through
the case sides. Water,dirt, dust or any foreign material
that can be drawn into the welder should be kept to a
minimum. Failure to observe these precautions can
result in excessive operating temperatures and
nuisance shutdowns.
Locate the INVERTEC
®
machine away from radio
controlled machinery. Normal operation of the welder
may adversely affect the operation of RF controlled
equipment, which may result in bodily injury or damage
to the equipment.
STACKING
The INVERTEC
®
machine may be stacked 3 high. Be
sure to locate the machines on a firm level surface and
align the pins in the roofs of the lower unit with the
holes in the base of the upper unit.
Two INVERTEC
®
CV /CC machines can be stacked
together through the two holes ( 1.1 ) and the two pins
( 1.2 ). Please see
FIGURE A.1.
The INVERTEC
®
CV/CC machine can be moved using
the handles ( 1.3 ). Please see FIGURE A.1 .

INPUT POWER AND GROUNDING
CONNECTION
Only a qualified electrician should connect the
input leads to the INVERTEC
®
. Connections should
be made in accordance with the connection
diagram. Failure to do so may result in bodily injury
or death.
Open the input box on the rear of the case. Use a
three-phase supply line, the three live wires should go
through the three holes of the input wire holder and be
securely clamped and fixed. Connect L1, L2, L3 and
ground according to the Input Supply Connection
Diagram decal, refer to Figure A.2 on this page.
Make sure the amount of power available from the input
connection is adequate for normal operation of the
machine. Refer to the Technical Specifications at the
beginning of this Installation section for recommended
fuse and wire sizes. Fuse the input circuit with the
recommended super lag fuse or delay type breakers.
Using fuses or circuit breakers smaller than
recommended may result in “nuisance” shut-offs from
welder inrush currents, even if the machine is not being
used at high currents.
