This kit is designed to protect the external grounding

circuit from being damaged by welding current. The

kit causes the output of the welding power source to

be de-energized if current is detected in the external

grounding circuit. Should this condition occur, the red

"fault" light on the power source control panel will light.

This kit consists of 70" long leads with a U-shape sen-

sor on one end and PC board connector on the other

end. It also includes 8 tie-wraps and 4 snap-in bases

for tie-wraps.

To install kit, proceed as follows:

Before installing this kit, make sure all primary

input power to the power source is disconnected

and/or lock out procedures are in place.

1. Remove 2 screws from the upper corners of the

control panel on the power source and open the

control panel.

2. Remove the top cover and both side panels from

the power source.

3. Disconnect the external grounding conductor from

the ground lug on the right rear A-frame leg.

4. Insert the external grounding conductor through

the U-shape sensor with the leads from the sen-

sor heading towards the inside of the power

source. Then reconnect the ground lead to the

ground lug.

Power Sources

DO NOT disturb the nuts on the sensor. This

sensor was factory assembled and preset to

the proper value.

5. Push in a tie-wrap base into the second hole of

the A-frame below the ground lug. Then tie wrap

the sensor to the tie-wrap base, making sure the

leads are still heading towards the inside of the

power source as shown in Fig. 1.

6. The leads should then pass under the top cross-

member to the right front leg of the A-frame; over

to the left front A-frame leg above the capacitor

bank; through the grommet of the control panel

along with other wiring harnesses; and then plug

in the leads into J2 header of the control pc board

assembly as shown in Fig. 2.

7. Insert the tie-wrap bases into the appropriate holes

in the A-frame legs and then tie- wrap the leads to

these bases. Do not allow too much slack along

the way especially over the capacitor bank.

8. Tie-wrap the leads to other wiring from left front

A-frame leg and through the control panel section

where appropriate.

9. Close control panel and secure with the two

screws previously removed. Reinstall the side

panels and top cover.

The power source is now ready for normal opera-

tion. When the red fault light is lit, immediately

turn OFF all primary input power to the power

source and turn OFF the power source input power

switch (S1). Locate and correct the fault.

After the fault has been corrected, apply input

power to the power source and turn the power

source input power switch (S1) ON. The power

source should now be ready for normal operation.
