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 appropriate National Electrical Code.

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.

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)

POWER CORD CONNECTION

A 5 meter power cord is wired into the machine.

Follow the power cord connection instructions. V350-PRO (CE) Incorrect connection may result in equipment damage.
