Startup
Visually inspect the installation thoroughly.
After completing the system installation and power system wiring, perform the following startup and test
procedure to ensure proper operation:
6.1
Check System Connections
• Ensure AC is off, battery breaker is off, and all power modules are removed from the shelf.
• Triple-check the polarity of all connections.
6.2
Verify AC and Power the Rectifier Shelf
• Install one power module.
• Verify AC input voltage is correct and turn on the corresponding feeder breaker.
• The power module OK LED should illuminate after a preset start delay.
• Using the CXCI (via web browser), test functionality of various module alarms and controls.
6.3
Check Battery Polarity and Connect
• Verify correct battery polarity using a voltmeter (ensuring no cells or batteries are reversed).
• Turn on battery breaker, as required, to the output of the system.
• Install remaining power modules.
• In the adjustments menu of the CXCI, set float and equalize voltage to the levels specified by the battery
manufacturer.
• Using the CXCI, test functionality of various module alarms and controls. In addition, perform a load test with
the system using a resistive load box as needed.
• Enable the temperature compensation (temp comp) feature (Batteries menu) and program the settings for
slope and breakpoints (upper and lower) with respect to the specific batteries used.
6.3.1
CXC Alarm Configuration for Nominal 120Vac Operation
The default setting for low AC voltage alarming is 180Vac. For nominal 120Vac operation, it is recommended to
reset this value to 100Vac.
To reconfigure this alarm parameter, go to “Alarms” – “Configure Alarms”. Under “Alarm Configuration,” select
“Voltage Alarms.” Select and modify the activation value for “AC Mains Low” to 100Vac. Submit changes to save
the new configuration.
