10.2 Replacing a Rectifier Module
The Cordex Converter (CXD) Rectifier (CXR) series modules are plug and play. When a rectifier module is added
to the system, the CXC will detect and update the inventory automatically. Replacing an installed rectifier requires
a manual Inventory Update at the controller to clear the removed rectifier from its current list of rectifiers.
1. To remove a module, loosen the screw on the bottom of the faceplate. Grasp the handle and pull it out,
sliding the module away from the rear connector and out of the shelf.
2. At the controller LCD initiate an Inventory Update as follows (or Main Menu > Rectifiers > Inventory Update for
the web interface):
FL + TC 54.00V 250A
Inventory Update
Rectifier Report
Converter Report
Tap the Rectifier icon on
the controller home page.
nventory Update clears the current list
of rectifiers and re-acquires all con-
nected modules.
3. Place the new rectifier module on the shelf bottom and slide the module into the rear connector (inside the
shelf). Apply pressure on the module handle to engage the rear connector in the shelf receptacle.
4. Tighten the screw on the bottom of the faceplate to secure the module to the shelf.
Tap Inventory Update.
A pop-up window appears with
a progress bar showing the
number of modules acquired
during the update.
WARNING!
Use extreme care when working inside the unit while the system is energized. Do not
make contact with live components or parts.
Circuit cards, including RAM chips, can be damaged by static electricity. Always wear a
grounded wrist strap when handling or installing circuit cards.
Ensure redundant modules or batteries are used to eliminate the threat of service inter-
ruptions while performing maintenance on the system’s alarms and control settings.
