108. System Start-Up Procedure
IMPORTANT: The Synchron inverter system is a sophisticated electronic backup power supply. Care must
be taken to follow the steps below in their exact sequence. Failure to do so will result in erroneous alarm
messages and possible equipment failure.
CAUTION: Familiarize yourself with the shut down procedure in section 300.1 before proceeding with the
Start Up.
1. Make sure the front cover/door is installed and secured shut.
2. Turn on the input circuit breaker in the building service panel serving as the AC disconnect to the Synchron
system.
3. Open the front access panel so that the input/output circuit breakers within the Synchron unit are accessible.
4. Turn on all output circuit breakers located within the Synchron system, and/or in the external Load Distribution
Panel (if any).
5. Hold the Pre-charge Switch in the “ON” position for 30 seconds.
6. Release the Pre-charge Switch and immediately turn ON the Main DC Switch.
7. Turn on the Main AC switch.
8. After approximately ve seconds, the system should turn on, the lighting loads should be energized, the front
panel green “AC-ON” and “LOAD” LEDs should illuminate.
109. SystemVerication
At this point, the connected load should be energized, the “Load” and “AC On” LEDs should be lit. Depending on
the state of charge of the batteries the inverter may or may not come on when the test switch is depressed. Allow a
24 hour charge period before testing the inverter system. If you need assistance, call Dual-Lite’s Technical Support
Center at 800-848-6439.
To simulate a power failure, simply press the test switch for a momentary test, or by opening the AC input circuit
breaker for a prolonged test. The inverter and the cooling fans (if any) will begin operating, the "AC On" LED will go off
and the "Load" LED will remain lit. All connected loads should be energized and operational, HID xtures should not
"wink-out".
Allow the inverter to run for several minutes or until satised with its operation. Close the AC input breaker to end the
test and return the unit to standby mode.
Note: It will take a few seconds for the unit to re-synchronize with the input line. The inverter will turn off
when synchronization is achieved.
