5.7 Alarm Connections
NOTE: To aid the user with installation, frequent reference is made to drawings located at the rear of this manual.
Custom configurations may be detailed within the Argus power system documentation package.
For terminal block connections, the recommended wire sizes are 0.14 to 1.50mm 2 (#26 to #16 AWG) for the
temperature range of 0 to 50 deg. C (as per UL/CSA).
CAUTION: to reduce risk of fire, use only 0.14mm
2
(#26 AWG) or larger wire.
Route via wire-ways and use existing cable clamps to secure to existing (factory) wire harness along with
customer run signal wires. Ensure signal wires are routed along hinge point of front door so door opening and
closing won’t require excess wire slack. Refer to Figure 12 for wire routing example.
Terminal block connections for the internal alarm card or CXCI I/O should be routed along the left side of the
DCP03 (looking at unit from front). Connections to the 4R/8D should be routed along the right hand side of the
DCP03. Refer to the customer connections (“–08”) drawing at the rear of this manual for details on terminal block
assignments.

5.8 CAN Serial Ports
Two CAN Serial ports (modular jacks with offset latches), for communications with Argus’ Cordex rectifiers and
other CAN-enabled equipment (nodes) on the same system, are located on the side of the rectifier shelf. CAN
ports may also be found on the optional 4R/8D ADIO Cordex peripheral (Figure 12).
Daisy-chain from node to node (CAN OUT of one shelf to CAN IN of another) as necessary and ensure that only
the last shelf is terminated as follows:
5.8.1 CAN Termination
A CAN termination jumper is located beside the rightmost rectifier connector on the front of the shelf backplane.
See the customer connections drawing for your shelf.
The CAN bus may be OPEN to the next node in the system or TERMINATED on the final node on the CAN bus.
