8. System Startup
Visually inspect the installation thoroughly.
After completing the system installation and power system wiring, perform the following startup and test proce-
dure to ensure proper operation:
8.1 Check System Connections
1. Make sure that the AC input power is switched off, the batteries are disconnected, and all the power modules
are removed from the shelf.
2. Triple-check the polarity of all connections.
8.2 Verify AC and Power the Rectifier Shelf
NOTE:
Insert the first module into the front left most position using the side of the shelf (or the
optional shelf-mounted controller) as a guide. Subsequent modules can be inserted us-
ing the previous module as a guide.
Do not force a module into position if it does not seat properly. All modules are keyed to
ensure that the correct module (voltage/polarity) type is used.
1. Install one power module.
a. Place the rectifier module on the shelf bottom and slide the module into the rear connector (inside the
shelf).
b. Apply pressure on the module handle to engage the rear connector in the shelf receptacle.
c. Tighten the screw on the bottom of the faceplate to secure the module to the shelf.
2. Verify that the AC input voltage is correct and switch on the corresponding feeder breaker. The power
module AC ON LED illuminates after a preset start delay. (See 3.1.1 for a description of the LEDs.)
3. Using the CXC, test the functionality of various module alarms and controls.
8.3 Triple Check Battery Polarity and Connections
1. Use a voltmeter to verify that the battery polarity is correct. Ensure that no cells or batteries are reversed.
2. Connect the batteries to the output of the system.
3. Install the remaining power modules.
4. In the adjustments menu of the CXC, set the float and equalize voltages to the levels specified by the battery
manufacturer.
5. Using the CXC, test the functionality of the various module alarms and controls. Perform a load test with the
system using a resistive load box.
6. Enable the temperature compensation (temp comp) feature in the batteries menu. Program the settings for
slope and breakpoints (upper and lower) according to the specific batteries used.
8.4 CXC Reset
The reset button located on the front panel of the optional CXC is used to restart the microprocessor. When
pressed momentarily, the unit beeps twice then resets. The front-panel LEDs illuminate temporarily but extinguish
after the system has finished its 15-second self-test.
