2.6 CXCM2 I/O Terminal Block (Option)
When using the DCP03 as a distribution solution for use with a 1.8kW rectifier shelf with a modular CXCM2
controller, an I/O terminal block can be installed in the UDC front door for front access to controller signals.
The CXCM2 terminal block kit comes with 25-pin, 15-pin, and 9-pin D-sub wire harnesses for connection to the
back of the 1.8kW rectifier shelf using the CXCM2 controller. Refer to the manual for the 1.8kW rectifier shelf (or
system).
The internal signals from the distribution center are wired to the CXCM2 I/O board direct from the internal alarm
board. The remaining relay outputs, digital inputs, and analog inputs are available on the board via terminal
blocks for customer connection of external signals. Refer to the customer connections (020–702–08) drawing at
the rear of this manual for details on terminal block assignments.

2.7 4R/8D ADIO or 8R/8D 8DIO (Option)
The 4R/8D ADIO or 8R/8D 8DIO Cordex peripheral can also be installed on the front door of the DCP03. The
4R/8D ADIO option expands the I/O capability of an existing Cordex controller by adding an additional 4 relays
outputs and 8 digital inputs. The 8R/8D 8DIO option expands the I/O capability of an existing Cordex controller by
adding an additional 8 relays outputs and 8 digital inputs.
The 4R/8D ADIO or 8R/8D 8DIO peripheral installs on the right side of the front door. They connect to the Cordex
system via CAN communications using RJ-12 offset communications cables.
All I/O connections are made via screw terminal blocks. Refer to the customer connections (020–702–08) drawing
at the rear of this manual for details on terminal block assignments.
NOTE: The 4R/8D ADIO option and the 8R/8D 8DIO option cannot be used in the same configuration with the CXCM2
I/O terminal block assembly. For applications requiring CXCM2 and ADIO/ 8DIO, one of the two devices must be
mounted externally to the distribution center. Consult factory for options.
