SECTION 4 - REPAIR/REPLACEMENT PROCEDURES
INTRODUCTION
This section explains how to replace a failed NIRL03 Remote
Link Termination Module.
MODULE REPLACEMENT PROCEDURES
If an IRL termination module is faulty, replace it with a new
one. To replace an IRL module:
1. Turn off power to the cabinet containing the defective IRL
module.
2. Remove (pull off) the front cover from the defective IRL
module.
3. Label and remove all wiring and cables from the defective
IRL module.
4. Remove the defective IRL module from the termination
mounting unit.
5. Verify a 1.0 amp/250 volt fuse is installed in fuse clip F1
and the 5.0 amp/250 volt fuse is installed in fuse clip F2 of the
replacement IRL module. If not already installed, insert the
appropriate fuses into fuse clips F1 and F2.
6. Set the jumpers on the replacement IRL module to match
the jumper settings of the defective IRL module.
7. Connect all wiring removed in Step 3 to the replacement
IRL module.
8. Verify proper wiring connections to the replacement IRL
module.
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
Il 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.
