3.1 Cordex Rectifier Shelves
Each bay can contain up to five Cordex shelves that hold up to six individual rectifier modules.
3.1.1 AC Termination Wiring
The individual Cordex rectifier shelves are wired to the customer-provided AC termination panel. The AC input is
routed through a 1" knockout for direct connection to the rectifier shelf with appropriately sized wire according to
the local electrical codes.
Each shelf requires two AC input circuits. The required input voltage varies depends on the rectifier shelf option
chosen at the time of ordering—see Table A for details.
3.1.2 Cordex Rectifier Modules (Purchased Separately)
See the Cordex rectifier shelf manual included with the system documentation package for detailed information.
The CXC controller provides central control of the rectifiers’ output level, load sharing, temperature compensation
and alarm reports. A CAN bus cable is wired or daisy-chained to each rectifier shelf for communication with the
Alpha CXC System Controller.

3.1.3 Rectifier Alarms and LEDs
Rectifier status, such as Mains OK, Minor and Major alarms, display on the rectifier front panel.
• When a Rectifier Major alarm is present, the module has shut down due to a critical fault.
• A Rectifier Minor alarm indicates the module has a noncritical alarm, however, it has not shut down.
See the Cordex rectifier manual included with the system documentation package for detailed information.
