ESD Ground Procedures and Equipment
The best protection against ESD is to keep the ground braids as short as
possible and connect them to a central point on the booth base as shown in the
Star diagram. Under normal conditions making Star connections is not a
problem, but in some systems, such as roll-on/roll-off booths, the ground braids
required for a Star connection are too long to be effective against ESD. In this
case, a Daisy Chain ground configuration is acceptable.
Figure 2 ESD Grounding Procedures and Equipment
Always use the special flat braided copper ESD ground cables furnished with all
Nordson spray gun controllers to ground them. The ESD ground cables should
always be attached to the welded booth base, not to a panel, enclosure, or other
component bolted to the base. Keep the cables as short as possible. If using a
grounding block kit, make sure the block is installed directly to the welded base
with the included self-drilling screws.
An ESD grounding block kit is available for connecting the ground braids to the
booth base. The kit contains two 6-position grounding blocks, fasteners,
terminals, and 15 meters (50 feet) of braided ground cable. If additional kits are
required, order:
