INSTALLATION   

A-3

SELECT SUITABLE LOCATION

The Invertec V350-PRO will operate in harsh environments.

Even so, it is important that simple preventative measures

are followed in order to assure long life and reliable opera-

tion.
• 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. Failure to observe these precautions

can result in excessive operating temperatures and nui-

sance shutdown.

• Keep machine dry. Shelter from rain and snow. Do not

place on wet ground or in puddles.

•  DO NOT MOUNT 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 .06”(1.6mm)

thick, which shall extend not less than 5.90”(150mm)

beyond the equipment on all sides.

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

STACKING

V350-PRO 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 GROUNDING CONNECTIONS

•  Only a qualified electrician should connect the Invertec

V350-PRO. Installation should be made in accordance

with the appropriate National Electrical Code, all local

codes and the information detailed below.

• When received directly from the factory, multiple voltage

machines are internally connected for  460VAC. If 460VAC

is the desired input, then the machine may be connected

to the power system without any setup required inside the

machine.

• Initial 200VAC - 415VAC and 575VAC operation will

require an Input voltage panel setup.

SAFETY PRECAUTIONS

ELECTRIC SHOCK 

can kill

.     

• TURN THE INPUT POWER OFF AT 

THE DISCONNECT SWITCH BEFORE

ATTEMPTING TO CONNECT OR DIS-

CONNECT INPUT POWER LINES, OUTPUT

CABLES, OR CONTROL CABLES.

• Only qualified personnel should perform this

installation.

• Connect the green/yellow lead of the power

cord to ground per U.S.National Electrical

Code.

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

WARNING

• Open the access panel on the rear of the machine.

• For 200 or 230: Position the large switch to 200-

230.

For higher voltages: Position the large switch to

380-575.  

• Move the "A" lead to the appropriate terminal.

POWER CORD CONNECTION

A 10 ft. power cord is provided and wired into the

machine. Follow the power cord connection instruc-

tions. 

• 

Incorrect connection may result in equipment

damage.

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

Single Phase Input

Connect green lead to ground per National Electrical

Code.

Connect black and white or brown leads to power.

Wrap red lead with tape to provide 600V insulation.

Three Phase Input

Connect green lead to ground per National Electric

Code.

Connect black, red and white or brown leads to

power.

CONNECTIONS OF WIRE FEEDERS TO V350-PRO 

LN-7 Connection Instructions

An LN-7 can only be used with the “Factory” &

Advanced Process

””

versions of the 350-Pro. 

• Turn the Invertec power switch "off".

• Connect the K480 control cable from the LN-7 to the

14-pin MS-style connector.

• Connect the electrode cable to the output terminal of

the polarity required by electrode. Connect the work

lead to the other terminal.

• 

Set the meter polarity switch on the front of the Invertec

to coincide with wire feeder polarity used.  The wire

feeder will now display the welding voltage.

• If K480 is not available, see connection diagram

S19404 for modification of K291 or K404 LN-7 input

cable with K867 Universal Adapter Plug.

• 

If a remote control such as K857 is to be used with the

LN-7, the remote can be connected directly to the 6-pin

MS-style connector on the front of the Invertec or use a

K864 adapter to connect the LN-7 and the remote to

the 14-pin MS-style connector. (See connection dia-

gram S19901)
