All seat cushions are grounded in a similar manner. The illustrations below detail the following instructions for grounding three typical types of truck seats.
ESD Precaution |
Install the LectroCount Ground Strap Kit before installing the LectroCount register. |
Follow these steps to ground a truck seat:
1.Identify any adjustable, shock absorbing seat in the truck cab. These seats will typically have pivot points, hinges, or other mechanical design features that make seat adjustments possible.
Grounded Passenger Seats |
Some truck seats, typically passenger seats, are not adjustable and do not require grounding. |
2.Find an existing screw or hole near the back of the seat frame, close to the cab floor. If a hole or screw does not already exist, drill a 9/32” hole in the seat frame.
3.Attach one end of the ground strap to the seat frame bracket using the lock washer, flat washer and nut provided.
Ensure a Good Ground |
Remove any dirt or oxidation from the ground strap contact point. Lock washers should penetrate any paint to ensure a good electrical connection. |
4.Find an existing screw or hole, or drill a 9/32” hole, in the part of the seat frame—above all pivots and adjustments—that is attached directly to the seat cushion. Make sure that there are no intervening pivot points, guides, adjustment mechanisms, etc., which could interfere with the ground path between the seat cushion and the ground strap.
•If the seat cushion has a wooden base, use a wood screw and washer to attach the strap lug to the bottom of the seat at a point where the seat fabric is attached to the wood. There must be good contact between the seat fabric and ground strap lug.
5.Use the wire ties provided with the kit and tie off the strap so that it doesn’t interfere with the movement of the seat and is clear of traffic areas in the cab.
6.Check the strap for a good ground connection (see below).
