mance and certification.
To replace a NIAI02 termination module:
1. Remove the termination module front cover.
2. Pull the termination module several inches from the TMU
backplane.
3. Label and remove all power and field wiring from the termi-
nal blocks.
4. Slide the TM out of the TMU.
5. Slide the new TM into the same slot as the module that was
removed.
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-
quement a ces instructions pourrait causer des dommages a
l'equipment. Ne pas rebrancher les alimentations avant d'avoir
verifie tous les raccordements.
CAUTION
Remove modules from their assigned slots before installing a
cable to that slot. Failure to do so could result in damage to the
module or station.
