22 Smart Star A/D Converter Cards (SR9300)
B.1 Selecting and Installing a Field Wiring Terminal
Connections to the I/O cards are made via a ribbon cable connector or optional field wir-
ing terminals that are either pluggable or have screw terminals. Three different Field Wir-
ing Terminals (FWTs) are available. Table B-1 lists the I/O cards and the Z-World part
numbers for the corresponding FWTs.
Before you can install the FWT you selected
for your I/O card, you must remove the tabs
from the connector on the I/O card. To do
so, move the tab inwards as shown in
Figure B-1. Then insert a screwdriver into
the space below the tab on the side of the
connector and gently nudge the tab up and
out. If you are careful, the tab will remain
intact to be saved and snapped back in place
for future use.
Plug the FWT connector into the connector
on the A/D converter card. Be sure to posi-
tion the pluggable or screw connectors so
that the edge of the FWT they are on faces
outwards from the A/D converter card as
shown in Figure B-2. Position the mylar
insulator above the FWT as shown in
Figure B-2 to protect the header pins on the
printed circuit board, and secure the FWT
using the two 4-40 × ¼ screws supplied.
