INSTALLATION
STEP #3
WIRING THE EMERGENCY BALLAST
> Determine the type of AC ballast installed in the fixture.
> Select the appropriate wiring diagram on back to connect the emergency ballast to the AC ballast and lamp(s). Make sure all connec-
tions are in accordance with the National Electrical Code and any local regulations.
> After installation is complete, supply AC power to the emergency ballast and join the inverter connector.
> At this point, power should be connected to both the AC ballast and the emergency ballast, and the Charging Indicator Light should
illuminate indicating the battery is charging.
> A short-term discharge test may be conducted after the emergency ballast has been charging for one hour. Charge for 24 hours before
conducting a long-term discharge test. Refer to OPERATION.
> In a readily visible location, attach the label "CAUTION - This Unit Has More Than One Power Connection Point.
To Reduce The Risk Of Electric Shock, Disconnect Both The Branch Circuit-Breakers Or Fuses And Emergency
Power Supplies Before Servicing."

OPERATION

When AC power is applied, the charging indicator light is illuminated, indicating the battery is being charged. When power fails,
the emergency ballast automatically switches to emergency power, operating one or two lamps at reduced illumination. When
AC power is restored, the emergency ballast returns to the charging mode and delays AC ballast operation for approximately
three seconds to prevent false-tripping of AC ballast (end-of-lamp-life) shutdown circuits. This emergency ballast will operate
the rated lamp load for a minimum of 90 minutes.

MAINTENANCE

Although no routine maintenance is required to keep the emergency ballast functional, it should be checked periodically to
ensure that it is working. The following schedule is recommended:
1.
Visually inspect the charging indicator light monthly. It should be illuminated.
2.
Test the emergency operation of the fixture at 30-day intervals for a minimum of 30 seconds. Either one or two
lamps should operate at reduced illumination.
3.
Conduct a 90-minute discharge test once a year. One or two lamps should operate at reduced illumination for
at least 90 minutes.
! REFER ANY SERVICING INDICATED BY THESE CHECKS TO QUALIFIED PERSONNEL !

WIRING DIAGRAMS

The following diagrams are typical schematics only.
May be used with other ballasts. Consult the factory
for other wiring diagrams. Emergency Ballast and AC
Ballast must be fed from the SAME BRANCH CIRCUIT.
