INSTALLATION
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
SAFETY PRECAUTIONS
SELECT SUITABLE LOCATION
The Invertec V350-PRO will operate in harsh environ-
ments. Even so, it is important that simple preventative
measures are followed in order to assure long life and
reliable operation.
• The machine must be located where there is free cir-
culation 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 nuisance 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 volt-
age 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.
CAUTION
• Initial 200VAC - 415VAC and 575VAC operation will
require an Input voltage panel setup.
• 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 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 leads to power.
CONNECTIONS OF WIRE FEEDERS TO V350-PRO
LN-25 Connection Instructions
(Factory, Construction &
Advanced Process versions
can be connected.-Not recommended for Pulse
Welding with the Advanced Process Model).
• Turn the Invertec power switch "off".
• Connect the electrode cable to the output terminal of polar-
ity required by electrode. Connect the work lead to the
other terminal.
• LN-25 with Remote Control options can be used with the
Factory Advanced Process version of the V350. The 6-Pin
(K444-1) and 14-pin (K444-2) remotes can be connected
directly to the 6-pin & 14-pin MS-style connectors. The 42
Volt Remote Voltage and Output Control (K624-1) Kit can
be connected to the V350’s 14-pin MS-style connector
using Remote Control Cable assembly K627- [ ]. LN-25s
with a K431-1 remote kit can be connected to the V350’s
14-pin MS-style connector using a K432 cable and K876
adapter. (See connection diagram S19899). Or the K432
cable could be modified with a K867 Universal Adapter
Plug (See connection diagram S19405) to connect it to the
V350’s 14-pin MS-style connector.
