INSTALLATION
A-2
SELECT SUITABLE LOCATION
The Invertec V350-PRO (CE) will operate in harsh
environments. Even so, it is important that simple pre-
ventative 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.
STACKING
V350-PRO (CE) 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 (CE). 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
440VAC. If 440VAC is the desired input, then the
machine may be connected to the power system
without any setup required inside the machine.
• Initial 200VAC - 415VAC 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.
• Move the "A" lead to the appropriate terminal.
POWER CORD CONNECTION
A 5 meter power cord is wired into the machine.
Follow the power cord connection instructions.
Incorrect connection may result in equipment damage.
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 appropriate National
Electrical Code.
----------------------------------------------------------------------
WARNING
Single Phase Input
Connect green/yellow lead to ground per National
Electrical Code.
Connect blue and brown leads to power.
Wrap black lead with tape to provide 600V insulation.
Three Phase Input
Connect green/yellow lead to ground per appropriate
National Electric Code.
Connect blue, black and brown leads to power.
CONNECTIONS OF WIRE FEEDERS TO V350-PRO (CE)
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
"CE" version of the V350. The 6 Pin (K444-1) and 14 pin
(K444-2) remotes can be connected directly to the 6 & 14
pin amphenols. The 42 Volt Remote Voltage and Output
Control (K624-1) Kit can be connected to the V350’s
24/42 VAC amphenol using Remote Control Cable
assembly K627- [ ]. LN-25s with a K431-1 remote kit can
be connected to the V350’s 24/42 VAC amphenol 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 24/42 VAC amphenol.
LN-7 Connection Instructions
• Turn the Invertec power switch "off".
• Connect the K480 control cable from the LN-7 to the
115VAC 14-pin wire feeder amphenol connector on
the rear of the Invertec.
• 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 amphenol on the front of the Invertec or
use a K864 adapter to connect the LN-7 and the
remote to the 115VAC 14-pin amphenol connector
on the rear of the Invertec. (See connection diagram
S19901)
