CXCM2 Replacement (as used with 1.8kW shelf)
Refer to all safety instructions provided in the documentation package provided with your system.
WARNING: HIGH VOLTAGE AND SHOCK HAZARD.
Use extreme care when working inside the shelf while the system is energized.
Do not make contact with live components or parts.
Circuit cards, including RAM chips, can be damaged by static electricity. Always wear a grounded
wrist strap when handling or installing circuit cards.
1. Write down the CXCM2 communication information: dynamic or static IP, IP address, and gateway.
2. Connect user laptop to CXCM2 per software manual; standard network crossover cable to Ethernet port.
3. A step-by-step connection (wizard) application (Windows® 2000 operating system) – provided to establish
remote communications with your CXCM2 – is available via the Argus website (The CXC Connection Wizard will save your LAN configuration and restore it back when exiting the
application.
4. Save CXC configuration file (see software manual).
5. Bypass system LVD using LVD Inhibit switch as required and remove signal wires (via DB connectors) from
CXCM2.
CAUTION: If the LVD is not bypassed, the DC loads will be shut down when the wiring to the
controller is removed.
6. Ensure rectifier is in the right-most position.

9. Review steps 1 through 3 with respect to new installation and upload the saved CXC configuration file to the
new controller.
10. Use a meter to verify the buss voltage and current shunt. Recalibrate as required due to differences in the
new CXCM2.
11. Replace rectifiers and signal wires. Return LVD Inhibit switch to normal.
