DC Output Connections
WARNING
Leave cables or bus bars disconnected at battery and verify output polarity using a voltmeter.
Make battery connections only after all other wiring is completed.
DC output wire shall be UL approved XHHW or RHH/RHW (for Canadian users, RW90 Type). Control and sense
wires shall be UL approved Style 1015 (for Canadian users, TEW type).
Connect DC output cables at the side of the shelf. Without the distribution option, the side DC access is made
toward the rear of the shelf.
Terminate cable leads with appropriate crimp lugs. Secure the positive and negative to the shelf output post of the
correct polarity; i.e., +Vcable to +Vpost. Ensure the washers are on the bolts in the same order in which they were
shipped from the factory. Tighten the bolts as per Customer Connections drawing at the rear of this manual.
The common output leg of the rectifier system should be connected to ground. This is typically done at the load
common termination point.
Replace rear cover once all connections have been completed.

CAN Serial Ports
Connect Cordex equipment and set jumpers as shown:
Figure 6–CAN ports for multiple shelf connections with CXCM
Serial ports, for communications with Apha’s Cordex
rectifiers and other CAN-enabled equipment, are located
on the backplane.
Daisy-chain from shelf to shelf as necessary and ensure
that the last shelf is terminated with the jumper (below).
List 0 (system equipped for CXCM)
has one CAN OUT port.
List 81 (equipped for six rectifiers
and no CXCM) has one CAN IN
port and one CAN OUT port.
The jumper (P1) allows setting of
the CAN OUT to be open to next
shelf or TERMINATED if last shelf
on CAN bus, as shown here:
