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 3-6 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:

Encoder, Photoeye, and Scanner Connections
A 25-conductor cable carries the encoder and discrete part ID and zone
input signals from the Photoeye Junction Box (PEJB) to the I/O board in the
iControl console. If these inputs are shared by a second booth then an
additional 25-conductor cable is supplied. Table 3-3 lists the 25-conductor
cable connections to be made at the terminal strip.
Section 7 contains a system wiring diagram, console wiring diagram, and
diagrams for the junction boxes and control panels listed in Table 3-3.
NOTE: Refer to your system plan views when locating the part ID stand
and mounting the photoeyes or scanners.
