When AC power is applied, the charging indicator light is illuminated, indicating that the battery is being charged. When
power fails, the emergency ballast automatically switches to emergency power (internal battery), operating one lamp at
reduced illumination. This emergency ballast will operate one 13 W through 42 W lamp for a minimum of 90 minutes. When
AC power is restored, the normal ballast operation is delayed by approximately three (3) seconds to prevent false tripping
of AC ballast (end-of-lamp-life) shutdown circuit. The temperature control circuitry assures the proper charging current and
battery protection under the full allowable ambient temperature range.
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. One lamp should
operate at reduced illumination.
3. Conduct a 90-minute discharge test once a year. One lamp should operate at reduced illumination for at least
90 minutes.

OPERATION
STEP #4 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 electrical connections in accordance with the National Electrical Code, Canadian 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."
MAINTENANCE
STEP #3 INSTALLING THE CHARGING INDICATOR LIGHT
> Install the CHARGING INDICATOR LIGHT as shown in the illustration below so that it will be visible after the
fixture is installed.
NOTE: After installing the charging indicator light and test switch, mark each with the appropriate label.
