For a Mobile ESD Cart
One "grounding post"
One connection per shelf to the "ground post" using an ESD Clip(TM) or metal split sleeve
Provides one connection to the ESD floor by the single "grounding post" contacting the conductive floor
OR, for a Mobile Cart:
Use an ESD Wheel (conductive wheel) for grounding a mobile ESD safe cart
Optional: to assure that a cart is grounded while at rest, connect a ground wire between the cart and an ESD ground when the cart is stationary using an ESD Clip + Ground Point
OR, for a mobile cart
Use Two ESD Wheels (conductive wheels) for grounding a mobile ESD safe cart
Use Four ESD Wheels (conductive wheels) for grounding a mobile ESD safe cart
Optional: To assure that a cart is grounded while at rest, connect a ground wire between the cart and an ESD ground when the cart is stationary using an ESD Clip + Ground Point
If you are considering conductive wheels, you have probably concluded that your "drag chains" or "grounding cables" are not working well for you. Conductive wheels are more reliable and less prone to corrosion and contamination than drag chains or cables.
While even 4 conductive wheels or posts will not provide a good connection to a dirty or non-functioning ESD floor, more connections means a higher probability of making a successful connection. With only one leg / wheel, you only have one possibility for connection. All it takes to disrupt the ESD ground connection is to move the cart onto a small scrap of paper or plastic or perhaps move the leg onto a place on the floor that is not conductive. In this case, more is better.
