Consult rectifier document #010-566-C0 for module installation, rectifier states and modes of operation. After
completing the shelf wiring and installation, perform the following startup and test procedure to ensure proper
operation:
1. Ensure all power modules and the CXCM are removed from the shelf. Verify correct battery polarity
using a voltmeter, and connect battery (if required) to the output of the system.
2. Install one power module and verify that the Module Fail LED illuminates (assuming a battery is
connected to the system providing backup power). This indicates correct output polarity.
3. Verify AC input voltage is correct and turn on the corresponding AC input feeder breaker. The AC and
ON LED should illuminate after a preset start delay and system will begin charging batteries.
4. Install remaining power modules and CXCM. In the adjustments menu of the CXCM, set Float and
Equalize voltage to the levels specified by the battery manufacturer.
5. Using the CXCM, test functionality of various module alarms and controls. In addition, perform a load
test with the system using a resistive load box as needed.
5.1 CXCM Reset
A reset button is located on the front panel for restarting the CXCM’s microprocessor. It takes approximately 15
seconds before the display reappears after pressing the reset button. To protect against accidental load disconnect,
see 4.15.1.1.
