Fluorescent Emergency Ballast
Installation
Instructions
! IMPORTANT !
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 leads, prior to installation,
battery connector must be open. Do not join battery connector until installation is complete
and AC power is supplied to the emergency ballast.
2. This product is for use with most 2’ through 8’ (17W - 215W) single or bi-pin fluorescent
lamps.
3. Please ensure that all connections are in accordance with the National Electric Code (NEC)
and other local regulations (if applicable).
4. To avoid the chance of electric shock, disconnect both normal and emergency power
supplies and the battery connector of the emergency ballast before servicing.
5. This emergency ballast is designed for factory or field installation in either the ballast
channel, or on top of the fixture.
6. Do not install this device near gas or electric heaters.
7. An AC power source is required (120 or 277VAC, 60Hz)
8. The battery used in this product is a sealed, no-maintenance unit, and is not field
replaceable. Contact the manufacturer for information on service.
9. The use of accessory equipment not recommended by the manufacturer may cause an
unsafe condition.
10. Do not use this emergency ballast for other than intended use.
11. Product servicing should only be performed by qualified service personnel.

INSTALLATION INSTRUCTIONS
WARNING: TO PREVENT HIGH VOLTAGE FROM BEING PRESENT ON RED, YELLOW &
YELLOW/BLACK OUTPUT LEADS PRIOR TO INSTALLATION, BATTERY CONNECTOR MUST
BE OPEN. DO NOT JOIN BATTERY CONNECTOR UNTIL INSTALLATION IS COMPLETE AND AC
POWER IS SUPPLIED TO THE EMERGENCY BALLAST.
NOTE: Please verify that the necessary branch wiring is available before continuing. An unswitched source of power is
required. The emergency ballast must be fed from the same branch circuit as the AC ballast.
STEP 1 ► Installing the Emergency Ballast
• Disconnect AC power from the fixture.
• Select the appropriate wiring diagram to connect the emergency ballast to the AC ballast and lamp.
• Refer to Diagram 1 to install the emergency ballast and test/monitor plate. Make electrical connections
in accordance with the National Electrical Code and any local regulations. The test/monitor plate may be
installed close to the fixture in the ceiling or at a remote location (up to 50 feet). The emergency ballast
may be remotely installed up to half the distance the AC ballast manufacturer recommends remoting the
AC ballast from the lamp, or up to 50 feet, whichever is less. If no AC ballast is used, the emergency ballast
can be remotely mounted up to 50 feet away.
Note: A switch box is not supplied.
STEP 2 ► Wiring The Emergency Ballast
• See page fore more detailed wiring schematics. The emergency ballast can be used with one or two lamp
fixtures, and operates one or two lamps in the emergency mode.
• Cut fixture wire between the lamp holder and AC ballasts and connect the blue and blue/white emergency
ballast wires to the AC ballast and the yellow and yellow/black wires to the lamp holder.
• On switched fixtures, an additional unswitched hot (120 or 277VAC) wire must be run to the junction box
and connected to the emergency ballast.
• The emergency ballast must be connected to an unswitched 120 or 277VAC power source. Do not connect
to other voltages. After fixture installation is complete, supply AC power to the emergency ballast, then join
the ballast connector.
STEP 3 ► Emergency Ballast Quick Check and Labeling
• For short-term testing of the emergency function, the battery must be charged for at least one hour. The
emergency ballast must be charged for at least 24 hours before conducting a long-term test.
• In a readily visible location, attach the label “CAUTION: This unit has more than one power supply
connection point. To reduce the risk of electrical shock, disconnect both the branch circuit breakers or
fuses and emergency power supplies before servicing.”

EMERGENCY BALLAST
OPERATION
When AC power is supplied to the emergency ballast, the charging light is illuminated; the battery is being charged at
this point. When power fails, the emergency ballast will switch over to the battery, and will operate one or two lamps
at reduced illumination. This emergency ballast will operate 6W through 42W lamps for a minimum of 90 minutes.
MAINTENANCE
NOTE: Emergency ballast servicing should only be performed by qualified personnel.
No routine maintenance is required to keep the emergency ballast functional, but it should still be checked periodically to
confirm that it is working correctly. The following should be performed as specified:
1. Inspect the charging indicator and confirm that it is lit.
2. At 30-day intervals, a short-term discharge test should be performed. The test switch should be held
for 30 seconds, and either one or two lamps should be functioning (at reduced illumination).
3. Annually, a long-term (90 minutes) discharge test should be performed. One or two lamps should
function for a minimum of 90 minutes
