INSTALLATION

INVERTEC® V450-PRO

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 V450-PRO with accessories attached to it.

STACKING

V450-PRO machines can be stacked to a maximum 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 V450-PRO away from radio controlled
machinery.

The normal operation of the V450-PRO may
adversely affect the operation of RF controlled
equipment, which may result in bodily injury or
damage to the equipment.

INPUT CONNECTION

Only a qualified electrician should connect the

input leads to the V450-PRO. Connections should

be made in accordance with all local and national

electrical codes and the connection diagram locat-

ed 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. A 1.75 inch (45 mm)
diameter access hole for the input supply is located on
the upper left case back next to the input access door.
Connect L1, L2, L3 and ground according to the Input
Supply Connection Diagram decal located on the
inside of the input access door or refer to Figure A.1 on
the following page.

SAFETY PRECAUTIONS
Read

this entire installation section before you

start installation.

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 working on the equipment.

• Do not touch electrically hot parts.

• Always connect the V450-PRO grounding lug

(located inside the reconnect input access door)

to a proper safety (Earth) ground.

----------------------------------------------------------

SELECT SUITABLE LOCATION

Do not use the Invertec® in outdoor environments with-
out appropriate protection. The V450-PRO 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 V450-PRO over combustible sur-

faces. 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 cir-
culate in through the rear louvers and out through the
case sides and bottom. Water, Dirt, dust, or any foreign
material that can be drawn into the welder should be
kept at a minimum. Failure to observe these precau-
tions can result in excessive operating 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 dis-
able 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)
