Output Cable Connections

The output leads are connected to the output termi- nals marked “+” and “-”. They are located at the lower right and lower left corners of the front panel. The CV 500-I provides Twist-Mate European weld cable con- nector receptacles.

K852 Twist-Mate European connector plugs are avail- able for the cable size to be used. The Export model includes two Twist-Mate plugs for 2/0 - 3/0 (70-95mm2) cable and S18737 installation instructions. This informa- tion is also located at the rear of this manual.

Installation of Field Installed Options

REMOTE OUTPUT CONTROL

(K857 WITH K864 ADAPTER OR K775 )

The K857 has a 6-pin MS-style connector. The K857 requires a K864 adapter cable which connects to the 14-pin connector on the machine.

The K775 consists of a control box with 28 ft (8.5m) of four conductor cable. This connects to terminals 75, 76, and 77 on the terminal strip and the case grounding

screw so marked with the symbol on the machine. These terminals are located behind the control panel on the front of the power source. This control will give the same control as the output control on the machine.

– 17 –

A “V” cable 12” (.30m) long to connect a K857 Remote Control (6 pin connector) with a wire-feeder (14-pin connector) and the machine (14-pin connec- tor). If a remote control is used alone the wire-feeder connection is then not used.

WARNING

ELECTRIC SHOCK can kill.

•Turn the power switch of the welding power source “OFF” before installing plugs on cables or

when connecting or disconnecting plugs to welding power source.

CAPACITOR DISCHARGE CIRCUIT (K828-1)

Circuit that mounts inside the CV 500-I. Recommended when:

1)CV 500-I is used in conjunction with any LN-23P or older LN-8 or LN-9 semiautomatic wire-feeder. Eliminates possible arc flash re-start of weld when trigger interlock is used. Not required with current LN-8 (above Code 8700), or LN-9’s with serial numbers above 115187 (manufactured after 12/83), or any LN-9 having an L6043-1 Power PC Board.

2)CV 500-I is used with an LN-22 equipped with an older K279 Contactor-Voltage Control Option. Eliminates electrode overrun when gun trigger is released. Not required when later K279 (above Code 8800) is used.

3)CV 500-I is used with any semiautomatic wire- feeder and possible small spark, if electrode touch- es work just after gun trigger is released, is objec- tionable.

Install per M17060 instructions included with the Kit.
