OTi30W Self Test Slim Emergency Driver
Installation and Troubleshooting Guide - PN: 57414
IMPORTANT SAFEGUARDS
WHEN USING ELECTRICAL EQUIPMENT, BASIC SAFETY PRECAUTIONS SHOULD
ALWAYS BE FOLLOWED, INCLUDI NG THE FOLLOWING:
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
1. This product is for use with an LED lighting load and supplies up to 10W of power at factory
programmed current with a voltage between 10.0 VDC and 55.0 VDC in emergency mode for
a minimum of 90 minutes.
2. Make sure all connections are in accordance with the National Electrical Code, Canadian
Electrical Code and any local regulations.
3. To reduce the risk of electric shock, disconnect AC power of the emergency driver and fuse
from fuse holder of the battery pack before servicing.
4. This emergency driver is suitable for factory and field installation. For field installation, please
see the instructions on page 3.
5. This product is suitable for damp locations where the driver case temperature is 75°C maximum
and battery pack case temperature is 55°C maximum.
6. Do not use for outdoor applications.
7. Product is not suitable for heated air outlets and wet or hazardous locations.
8. Do not install near gas or electric heaters.
9. The use of accessory equipment not recommended by the manufacturer may cause an unsafe
condition.
10. Do not use this product for other than intended use.
11. Equipment should be mounted in locations and at heights where it will not readily be subjected
to tampering by unauthorized personnel.
12. Servicing should be performed by qualified service personnel.
13. Use caution when servicing batteries.
SAVE THESE INSTRUCTION
THIS PRODUCT CONTAINS A RECHARGE A B LE NI CK EL-CADMIUM
BATTERY. THE BATTERY MUST BE RECYCLED OR DISPOSED
PROPERLY.
Normal Mode Operation
When AC power is applied, the driver is in normal mode where the output current is at the
programmed setpoint. The Illuminated Test Switch light is ON (not flashing) indicating the batteries
are being charged.
Emergency Mode Operation
When power fails, the emergency driver automatically switches to emergency power, operating the
emergency LED load at required illumination. When the AC power is restored, the emergency driver
returns to the Normal Mode of Operation. This emergency driver will operate an LED lighting load with
a voltage between 10.0 VDC and 55.0 VDC and up to 10W of output power. The LED driver ensures
that there is light output for a minimum of 90 minutes.
Self-Testing Operation
The OSRAM self-testing emergency driver unit contains a control/monitor circuit that automatically
performs a 30-second discharge test once a month and a full 90-minute discharge test once a year.
During automated routine testing, the self-testing emergency driver simulates an AC power failure
causing the unit to automatically switch to emergency mode. The unit monitors the operation of the LED
load, battery voltage and LED load connections. If the unit detects any failures, the indicator light will
flash as per failure condition (see Troubleshooting section) until the condition has been corrected and
the unit passes the next test. To reset a failure indication, push the three wire Illuminated Test Switch
for at least 5 seconds. If t he d riv er detects that condition has not been cor rected, the uni t will detect the
failure and signal the failure condition.

Installation Instr uctions
DO NOT CONNECT BATTERY PACK TO DRIVER
UNTILL ALL INSTALLATION & WIRING IS COMPLETE. AFTER
INSTALLATION & WIRING COMPLETE, CONNECT BATTERY PACK TO
NOTE: Make sure the necessary branch circuit wiring is available. An unswitched source of power is
required and must be from the same branch circuit.
This product is suitable for field installation with suitable LED loads including LED luminaires, DC
voltage driven LED replacements for fluorescent lamps and others. There are a set of checks that
need to be carried out to determine if your luminaire is eligible for field installation.
1. Ensure the LED load’s rated power/current is greater than or equal to the Emergency Mode
and Normal Mode power/current output of this LED driver.
2. This is to ensure that this product will not produce more power/current in either modes than
the LED load can handle, thus ensuring that the LED load will not be damaged when the
system is operating.
3. The Normal and Emergency Mode output current can be programmed in a given range that is
dependent on the model type. Please refer to the product specification for the exact range. For
more information on programming instructions, please refer to www.osram.us
4. The emergency mode power should be less than or equal to rating of the driver and the
battery pack that is being used for the application.
5. Verify that the forward voltage of the luminaire’s LED array is within the limits of the
emergency LED driver and its programmed settings. The forward voltage of the LED array is
commonly designated as V
specifications, or imprinted directly on the LED arrays. If multiple LED arrays are to be driven,
and should be found on the luminaire markings, in the luminaire
