Step 3
Use the crimping tool to secure the grounding cable in the grounding lug.
Step 4 Remove the adhesive label from the grounding pad on the chassis.
Step 5
Place the grounding lug against the grounding pad so that there is solid metal-to-metal contact, and insert the two screws
with washers through the holes in the grounding lug and into the grounding pad.
Step 6 Make sure that the lug and cable do not interfere with other equipment.
Step 7
Prepare the other end of the grounding cable and connect it to an appropriate grounding point in your site to ensure
adequate earth ground.
