Terminal Block Wiring
The polarity and use of each terminal depends on the configu-
ration of the TDI. Refer to Figure
for general I/O point ter-
minal block assignments. Refer to the appendices for specific
application I/O point terminal block assignments and point
wiring polarity. A 12 AWG to 22 AWG wire should be used for
field wiring.
NOTES:
1.
Proper polarity wiring is required for DC signals.
2.
There are only 30 pins on the master/slave module P3 connec-
tor; the termination unit can handle 16 I/O points. When using points
7 and 8 of each group, the positive (+) side of these points share a
pin (A7 - A8 and B7 - B8). Refer to Table
Each installation is unique, presenting a special set of require-
ments and operating conditions. Refer to the
Site Planning,
Preparation and Equipment Installation Product Instruc-
tion, I-E93-900-5
for analog and digital I/O line wiring
requirements. It provides a general description of wiring rec-
ommendations for process I/O signals.
System Power Connections
Some I/O configurations require system power (24 VDC, 125
VDC or 120 VAC). Three terminals (E1, E2 and E3 common)

CAUTION
We strongly recommend that you turn the cabinet power off
before doing any termination unit wiring. Failure to do so could
result in equipment damage. Do not apply power until you ver-
ify all wire connections.
ATTENTION
Il est fortement recommande de debrancher l'alimentation elec-
trique du cabinet avant d'effectuer toute connexion aux cartes
de raccordement du chassis. Des dommages aux equipements
pourraient survenir dans le cas contraire. Ne pas rebrancher
l'alimentation avant que toutes les connexions aient ete veri-
fiees.
