DualLite LSN - System Start-Up and Verification

22
CAUTION: If a Make Before-Break type bypass switch is being used, equipment will be damaged
if the switch position is changed while AC line voltage is applied and the LSN system is turned off
or operating in inverter (DC) mode. Make sure the LSN system is running on line (AC mode) and supplying
output voltage before changing the bypass switch position. See the instructions supplied with your bypass
switch.
7. Turn the bypass switch to the “LINE" position. Using an AC voltmeter, verify the voltage to your protected
equipmentloadiscorrect.VoltagecanbeveriedattheLoadDistributionPanel.
8. Turnthebypassswitchtothe“UPS”positionandmeasurethevoltagetoyourprotectedequipmentloadonce
more(attheLoadDistributionPanel).Verifythevoltageiscorrect.
9. If all readings during the voltage and phase check are acceptable, reattach the bypass switch cover. Tighten the
retaining screws securely. Proceed to Section 110 to complete the system start-up.

110. Start-Up Procedure
FACTORY START UP: A Factory Start Up is provided standard with this unit. Please contact Dual-Lite's
Technical Support Center.
IMPORTANT: The LSN inverter system is a sophisticated electronic back-up power supply. Care must be
taken to follow the steps below in their exact sequence. Failure to do so will result in errone-
ous 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. Turn on the input circuit breaker in the building service panel serving as the AC disconnect to the LSN
system and check for proper voltage and phasing on the AC Input terminal block.
2. Turn on all output circuit breakers in the external Load Distribution Panel.
3. Close and lock the main cabinet door to the LSN Inverter cabinet.
4. Open the LSN system Circuit Breaker access door.
5. Turn on the output circuit breakers (if any).
6. TurnontheLSNMasterOn/OffSwitch.Caution:Thisisalockingtoggletypeswitch.Pullitouttowards
you to move it to the "ON" position.
7. Hold the Pre-charge Switch in the "ON" position for 10 seconds.
8. Release the Pre-charge Switch and immediately turn ON the Main DC Switch.
9. Turn on the Main AC switch.
10. Afterapproximatelyveseconds,thesystemshouldturnon,thelightingloadsshouldbeenergized,
the front panel "AC-ON" and "READY" LEDs should illuminate, and the system LCD display will begin to
scroll the system parameters.
11. Depending on the state of charge of the batteries, the front panel Charging LED may illuminate.
111. SystemVerication
Atthispoint,theconnectedloadshouldbeenergized,the"Ready"and"ACOn"LEDsshouldbelit,andthedisplay
isscrollingthrough18operatingmessages.Wait2minuteswhilethesystemcompletesitsnalsetup,andthenlook
at the various messages and make sure they are within expected limits. If any alarms sound, go to section 205 for
further instructions. If you need assistance, call Dual-Lite's Technical Support Center at 800-848-6439.
If no alarms sound, perform the following inverter test to verify its operation:
Once the “Ready” LED is illuminated, simulate a power failure by opening the AC input circuit breaker. The inverter
andthecoolingfanswillbeginoperating.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.
