The NIAI02 inserts into a standard INFI 90 termination mount-
ing unit (TMU) and occupies one slot. To install:
1. Verify slot assignment of the NIAI02 module.
2. Align the NIAI02 module with the guide rails in the TMU
and partially insert the module. Leave enough room to connect
terminal wiring and cables.
Completely seat the module after cabling and termination wir-
ing is attached.
Terminal Wiring
Connect the wiring from the thermocouple or millivolt signal
sensing the process to the termination module terminals. For
new installations, refer to the
manual for information on I/O wiring.
shows the terminal assignments for each input and
a field input termination example.
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
Ll est fortement recommande que toutes les alimentations
(armoire, E/S, etc.) soient coupees avant d'effectuer quelque
raccord que ce soit sur une carte de raccordement. Un man-
