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-PRO will operate in harsh environ- ments. Even so, it is important that simple preventa- tive 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.

CAUTION

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.

•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.

CAUTION

•Incorrect connection may result in equipment damage.

LN-25 Connection Instructions

(Factory, Construction & Advance Process versions can be connected.-Not recommended for Pulse Welding in the Advance Process version).

•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 K1728-1 and K1728-4 versions 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 24/42 VAC connector using Remote Control Cable assembly K627- [ ]. LN-25s with a K431-1 remote kit can be connected to the V350’s 24/42 VAC 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 24/42 VAC connector.
