Connect via screw terminations, hot (–) and return (+), for each fuse position.
The maximum allowable output current of the GMT box is 30A distributed over some or all of the ten
GMT fuse positions. The largest current that can be accommodated is 10A with a fuse of up to 15A.
If using a 15 A fuse, leave the adjacent fuse position(s) empty.

DC Output for Model 030-835-20/ 030-845-20 (bulk distribution)
Models 030-835-20 and 030-845-20 have no integrated distribution. Output connections are made
using 1/4" on 5/8" center 2-hole lugs that connect to the main output bars similar to the 030-851-20
battery terminations.

CAN Ports
The 3 and 4-module shelf, 1RU model with CXCM1+ or CXCM1 HP, has a single CAN port for commu-
nications with CAN-enabled equipment (nodes). It is located on the side of the shelf. The 5-module shelf
has two ports, located on the rear. The 2RU shelf has one port on the side.
Daisy-chain from node to node (CAN OUT of one node to CAN IN of another) as necessary and ensure
that only the last node is terminated.
•
4-module shelf – termination IN – default
•
5-module shelf – termination OUT – default

NOTE
:
This system has a limit of twelve Cordex 1.2kW rectifiers; due to available power from CAN Bus.
They do not have self-powered CAN Bus nodes.
Network Connection and Remote Communications via the Controller
Alpha’s Cordex rectifier shelf systems can be set up, monitored and tested via modem or Ethernet
10/100 Base-T serial data connection. The communication protocol supports a web interface. Some
standard scenarios are described in the following sections.
Ethernet Port for Network Connection
The Ethernet port is designed for controller connection to a user supplied network (TCP/IP secured by
user) via a front panel RJ-45 jack.
Connect to the controller using a standard network cable. Pinouts are shown in the connection draw-
ings.
Ethernet Port for Local Connection
Local access (e.g. laptop computer) is also possible from the Ethernet port connection using a standard
network cable.
NOTE
:
Older CXCM1+ models must use a crossover Ethernet cable for direct connection to a computer.
Signal Wiring Connections
For terminal block connections, the recommended wire sizes are #16 to #26 AWG (1.5 to 0.129mm
2
).
Control and sense wires shall be UL approved Style 1015 (for Canadian users, TEW type).
CAUTION
:
To reduce the risk of fire, use only #26 AWG (0.129mm
2
) or thicker wire.
