connector. Swing the “Display” panel back to its vertical position and install the two screws to hold the panel in
position. Do not tighten the screws very much, since they will be removed again.
2.3.3.2 System Personalization
Before installing the power modules into the receiver rack, apply the 48 DC input voltage (44 to 56VDC). The
controller (microprocessors) within the unit should become activated. The “Status” indicators on the “Display” panel
should sequence through their self test mode, changing from “red” to “yellow” to “green”, then momentarily off in
approximately 4 seconds. After this, ignore all the LED displays. Using the “Lap-Top” PC, call up the “Filed Service
Set-up” program. In the “Windows” menu, select the desired AC output voltage, frequency, and modes of
operation*. The “Windows” menu will appear similar to the following:
TYPICAL “WINDOWS SET-UP MENU
AC output voltage 100 110 115 120
AC output voltage 200 220 230 240
Output frequency 50 HZ 60 HZ
Restart AUTOMATIC MANUAL RESTART
AC bypass available YES NO
After the selections are complete, click on the “GO” box. The data will be sent to the appropriate address in the
controllers “EEROM”. Data will be fed back as text to the screen so as to verify that the “EEROM” was set up
properly. Verify that data sent is correct, or repeat this step until the correct data is obtained. Remove the applied
48VDC to the system by turning off the main DC feed circuit breaker.
*Note: This software has not been developed at present.
2.3.3.3 Redundant Controller Set-Up
After making sure the 48VDC power has been removed from the unit, remove the two “Phillips” head screws from
the “Display” panel as above. Re-install the top “controller” printed board that was previously partially removed.
Using the circuit board retaining bracket, disengage the bottom “controller” board from its connector. Replace the
“Display” panel and secure it with the two “Phillips” head screws previously removed. Repeat step 3.3.2 for this
second “controller”. When the set-up is complete, remove the 48VDC applied to the system. Again open the front
“Display” panel and reseat the bottom “controller” circuit board. Replace the circuit board retaining bracket and
secure it in its final position using the two 6-32 “Phillips” head screws. Replace the “Display” panel and secure it to
the rack using the two 8-32 x 3/8” “Phillips” head screws. Set up is complete.
2.3.4 Power Module Installation
The power modules are designed to be “hot swap”. However, for initial start up, all of the power modules should be
installed. In a system where all of the module positions are not used, reinstall the previously removed blank panels in
these locations. Install the “power modules” and tighten the four thumbscrews on each module. Before turning on the
main source DC circuit breaker and utility AC circuit breaker (if used), make sure that all of the “power module” circuit
breakers (upper left-hand corner) of each module is OFF. Also verify the ON/Stand-by” switch on the “Display” panel
is in the OFF (down) position. The inverter plant usually supplies power to some type of distribution circuit breaker
panel. Confirm that all of these circuit breakers (loads) are OFF before starting up the inverter. After the DC input cable,
utility line cable, and output cable are properly connected and secured, the inverter system is ready to be turned ON.
2.3.5 Start-Up Sequence
Confirm that all power modules’ ON/OFF circuit breakers are set to the OFF position. On the LCD “Display” panel,
be sure inverter switch SW1 is set at OFF position.
