EXTERNAL GROUNDING CONDUCTOR PROTECTION KIT
Item No. 36098
for V352, V382, V 452, V 582, V 652cvcc and V 782cvcc
Power Sources
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 sen­sor 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 sen­sor heading towards the inside of the power source. Then reconnect the ground lead to the ground lug.
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 cross­member 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 opera­tion. 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.
Be sure this information reaches the operator. Y ou can get extra copies through your supplier .
