Terminal Wiring
Field and power wiring must be connected to the terminal
strip. See Figure
for IAO terminal strip assignments.
Figure
shows how to wire field equipment. To connect field
and power wiring:
NOTES:
1.
Proper polarity of all signals must be maintained.
2.
For internal (system) power, use the 24 VDC supplied from the
system bus bar to the TMU unit bus bar.
3.
For external power, use the external supply connected to the
TMU unit bus bar.
4.
The external power supply common must be connected to the
system common.
1. Insure the IAO termination module is pulled out far enough
to gain access to the terminal strip.
2. Feed the field wiring into the terminal strip area and con-
nect them to the appropriate analog output terminals. The
auxiliary ground terminals are used for connecting field wiring
shields.
3. Connect an 18 AWG wire from the +24 VDC bus of the ter-
mination mounting unit to the +24 VDC terminal of the IAO
termination module.
4. Connect an 18 AWG wire from the common bus of the ter-
mination mounting unit to the common terminal of the IAO
termination module.
5. Connect an 18 AWG wire from the ground terminal of the
IAO termination module to the cabinet chassis ground bolt.
6. Insert the module until it locks securely into place.
7. Replace (snap on) the front cover.
CAUTION
It is strongly recommended that all power (cabinet, I/O, etc.) be
turned off before doing any termination module wiring. Failure
to do so could result in equipment damage. Do not apply
power until all connections are verified.
ATTENTION
II est fortement recommand, que toutes les alimentations (arm-
oire, E/S, etc.) soient coupées avant d'effectuer quelque rac-
cord que ce soit sur un carte de raccordement. Un
manquement à ces instructions pourrait causer des dommage
à l'équipement. Ne pas rebrancher les alimentations avant
d'avoir vérifié tous les raccordements.
