SAFETY PRECAUTIONS
WARNING
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.
----------------------------------------------------------------------
SELECT SUITABLE LOCATION
The Invertec V350-PIPE 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.
CAUTION
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-PIPE 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-PIPE. 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.
• Initial 200VAC - 415VAC and 575VAC operation will
require an Input voltage panel setup.
INSTALLATION
• 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 leads to power.
CONNECTIONS OF WIRE FEEDERS TO V350-PIPE
LN-25 Connection Instructions
• Turn the Invertec power switch "off".
• Connect the electrode cable to the output terminal of
polarity 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 con-
nected 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 con-
nector 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 con-
nect it to the V350's 14-pin MS-style connector.
