INSTALLATION INSTRUCTIONS
! IMPORTANT SAFEGUARDS !
WHEN USING ELECTRICAL EQUIPMENT, BASIC SAFETY PRECAUTIONS SHOULD ALWAYS BE
FOLLOWED, INCLUDING THE FOLLOWING:
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
1. To prevent high voltage from being present on red & yellow output leads prior to installation,
inverter connector must be open. Do not join inverter connector until installation is complete and
AC power is supplied to the emergency ballast.
2. This product is for use with most 32 W through 40 W single pin or bipin fluorescent lamps,
including energy saving, circline, U-shaped and rapid-start (4-pin) long compact fluorescent
lamps.
3. Make sure all connections are in accordance with the National Electrical Code and any local
regulations.
4. To reduce the risk of electric shock, disconnect both normal and emergency power supplies and
inverter connector of the emergency ballast before servicing.
5. This emergency ballast is for factory or field installation in either the ballast channel or on top of
the fixture.
6. This product is suitable for damp locations where the ambient temperature is 0°C minimum,
+50°C maximum. Product is not suitable for heated air outlets and wet or hazardous locations.
7. An unswitched AC power source is required (120 or 277 VAC, 60 Hz).
8. Do not install near gas or electric heaters.
9. Do not attempt to service the battery. A sealed, no-maintenance battery is used that is not field
replaceable. Contact the manufacturer for information on service.
10. The use of accessory equipment not recommended by the manufacturer may cause an unsafe
condition.
11. Do not use this product for other than intended use.
12. Servicing should be performed by qualified service personnel.
CAUTION: Verify that all replacement lamp types marked on the installed luminaire are also identified
as suitable for use with this inverter/charger pack.

INSTALLATION
WARNING: TO PREVENT HIGH VOLTAGE FROM BEING PRESENT ON RED AND YELLOW
OUTPUT LEADS PRIOR TO INSTALLATION, INVERTER CONNECTOR MUST BE OPEN. DO
NOT JOIN INVERTER CONNECTOR UNTIL INSTALLATION IS COMPLETE AND AC POWER
IS SUPPLIED TO THE EMERGENCY BALLAST.
NOTE: Make sure the necessary branch circuit wiring is available. An unswitched source of power is
required. The emergency ballast must be fed from the same branch circuit as the AC ballast.
1. Disconnect AC power from the fixture. Remove the ballast channel cover and install the emergency ballast
either in the ballast channel (see Illustrations 1 & 2) or on top of the fixture* (see Illustration 3).
mounting distance must be less than half the maximum remote mounting distance for the AC ballast. Consult AC
ballast manufacturer before remote installation.
2. Select the appropriate wiring diagram to connect the emergency ballast to the AC ballast and lamp. Make sure
all connections are in accordance with the National Electrical Code and any local regulations.
* Remote
ILLUSTRATION 1
*For installation on top of the fixture, wire bundle covers may be required by state or local codes. These covers are available from the
manufacturer as an accessory kit and must be ordered separately. Call your local distributor or the factory for complete infomation.
3. Install the test switch through the ballast channel cover of a troffer or through the side of a strip fixture. Drill
a 1/2" hole and install the switch as shown (see Illustration 1 & 2). Wire the test switch so that it removes AC
power from both the emergency ballast and the AC ballast at the same time (see wiring diagrams).
4. Refer to Illustration 4 and install the charging indicator light 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. If
a detached charging indicator light is used, connect by matching wire colors and install as shown
in Illustration 4.

5. 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.”

NOTE: After installing the charging indicator light and test switch, mark each with the appropriate label.
6. After installation is complete, supply AC power to the emergency ballast and join the inverter connector.
7. 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.
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 lamp 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. 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.
REFER ANY SERVICING INDICATED BY THESE CHECKS TO QUALIFIED PERSONNEL.
