INSTALLATION
CAUTION: DO NOT JOIN BATTERY CONNECTOR UNTIL INSTALLATION IS
COMPLETE AND AC POWER IS SUPPLIED TO THE EMERGENCY DRIVER.
NOTE: Make sure the necessary branch circuit wiring is available. An unswitched source of
power is required. The emergency driver must be fed from the same branch circuit
as the AC driver.
This product is suitable for field installation with suitable LED loads. There are Three (3) checks to
determine if your luminaire is eligible for field installation.
1. Ensure the LED load’s rated power is greater than or equal to the power output of this emergency LED
driver. This is to ensure that this emergency product will not produce more power than the LED load
can handle. Thus ensuring that the LED load will not be damaged when the system is in the emergency
mode.
2. Verify that the forward voltage of the luminaire’s LED array is within the limits of this emergency LED
driver. The forward voltage of the LED array is commonly designated as Vf and should be found on the
luminaire, in the luminaire specifications, or imprinted directly on the LED arrays. If multiple LED arrays
are to be driven, verify that the total forward voltage is within the limits of this product. Using a voltage
meter, it may be possible to directly measure the voltage across the LED arrays when operating from
the AC driver.
3. Ensure the output current of the LED driver does not exceed 5.0 Amps. This is the current into the
red/blue output wire.
NOTE: This product has been designed to reliably interface with a wide selection of LED loads and is
electrically compatible with every simple LED array that meets criteria 1 and 2 above. However
compatibility cannot be guaranteed with all current and future LED systems. Compatibility testing of the
end-use systems is suggested . Please contact the factory with any questions.
NOTE: After installation, it will be necessary to measure the egress lighting illumination level to ensure it
complies with national state and local code requirement.
Installation of this emergency LED driver will vary based on the luminaire type, however generally follow
these steps.
STEP #1 INSTALLING THE EMERGENCY DRIVER
Disconnect AC power from the LED luminaire.
Mount the emergency LED driver by the mounting tabs using appropriate screws(not
provided). The luminaire’s installation instructions may provide guidance on the
recommended mounting location.

3
NOTE: Considerations must be made to protect the wires on the models have no flexible conduit if
installed outside of the luminaire.
Note:
If the application requires the emergency LED driver to be mounted on
top of the luminaire, please use the models which provide metal flexible
conduit instead of bare wire.
Mounting Height: Many factors influence emergency illumination levels, such as the lamp load
selected, luminaire design, and environmental factors. Therefore end-use verification is necessary. For
field installations, the mounting height of illumination must be measured in the end application to
ensure the minimum lumens requirements on national, state, and local codes are satisfied.
Lumens can be calculated by the following formula:
Lumens in Emergency Mode = Lumens per Watt of Fixture * Output Power of Chosen Product
_______________(Lumens) = _____________(lm/W) * ____________(W)
Remote Mounting: The emergency LED driver may be remote mounted from the luminaire. If used in
conjunction with an AC driver the allowed distance is up to half the distance the AC driver
manufacturer recommends remote mounting the AC driver from the LED load. If used without an AC
driver, and remote mounting more than 18 feet from the luminaire, please consult the factory to
determine the necessary wire gauge. CAUTION: Remote mounting can result in reduced power output.
STEP #2 INSTALLING THE 4-WIRE TEST SWITCH ON FIXTURE SURFACE
Mount the supplied 4-wire illuminated test switch in a location that is visible and accessible by
maintenance personnel. The switch mounts through a hole which may need to be added to the
luminaire or could come pre-punched by the luminaire supplier.
Wire the test switch per wiring diagrams provided on these instructions.
If wired correctly, the test switch indicator light should be “ON”when AC power is supplied to the
fixture, and the battery switch is “ON” indicating that the emergency inverter battery is charging.

STEP #3 WIRING THE EMERGENCY DRIVER
Select the appropriate wiring diagram to connect the emergency driver to the AC driver and LED load.
Make sure all connections are in accordance with the National Electrical Code and any local regulations.
After installation is complete, supply AC power to the emergency driver and turn on battery switch/join
battery connector. At this point, power should be connected to both the AC driver and the emergency
driver, and the Charging Indicator Light should illuminate indicating the battery is charging.
A short-term discharge test may be conducted after the emergency driver has been charged for one hour. A
24-hour charging period must be performed before conducting a long-term discharge test. Refer to the
OPERATION section of specs.
"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
During normal operation AC power is applied to the driver and the charging indicator light is illuminated,
which indicates that the battery is being charged. When power fails, the emergency LED driver will
automatically switch to emergency power (internal battery), operating the LED load for a minimum of 90
minutes. When AC power is restored, the emergency driver returns to the charging mode.
MAINTENANCE
Although no routine maintenance is required to keep the emergency driver 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. If the charging indicator
is off, contact tech support.
2. Test the emergency operation of the fixture at 30-day intervals for a minimum of 30 seconds. The LED
load should operate at reduced illumination.
3. Conduct a 90-minute discharge test once a year. The LED load should operate at reduced illumination
for at least 90 minutes.
