Exceeding maximum ratings for operation and storage temperature will reduce expected life time or destroy the LED Module.
Exceeding maximum ratings for operation voltage will cause hazardous overload and will likely destroy the LED Module.
The temperature of the LED module has to measured at the Tc-point according to EN60598-1 in a thermally constant status with a temperature sensor or a temperature
sensitive label (available e.g. at RS-Components). For exact location of the Tc-point see drawing below.

Safety Information
The LED module itself and all its components may not be mechanical stressed.
Assembly must not damage or destroy conducting paths on the circuit board.
To avoid mechanical damage to the connecting cables, the boards should be attached securely to the intended substrate. Heavy
vibration should be avoided.
Detach each circuit board unit of the module only by severing the connecting cables (with power disconnected).
The LED Module incorporates no protection against: Short circuits, Overload, Overheating. Therefore it is absolutely necessary to
operate the modules with a electronically stabilised power supply offering protection against the above mentioned safety risks.
For dimming applications attention should be paid to specific references in "OPTOTRONIC Technical Guide".
Parallel connection is highly recommended as safe electrical operation mode.
Serial connection is not recommended. Unbalanced voltage drop can cause hazardous overload and demage the LED module.
Installation of LED modules (with power supplies) needs to be made with regard to all applicable electrical and safety standards.
Only qualified personnel should be allowed to perform installations.
Correct electrical polarity needs to be observed. Wrong polarity will result in no light emission.
OSRAM OPTOTRONIC power supplies are specifically designed with the necessary protection features for
safe operation.
When using other power supplies other than OPTOTRONIC the following basic safety features are required, in addition to any other
application specific concerns and local safety codes:
Short circuit protection
Overload protection
Overheat protection
Correct output voltage
Electrical contact is achieved with the contact cables. A maximum of 3 modules can be installed consecutively from one power
feed. Operation with more than 3 consecutive BACKlight modules will reduce photometric performance and exceed the current
carrying capacity of the module.
The BACKlight can typically survive transient current levels of up to 2 Amperes. As a general design precaution, if the maximum
output current of the power supply is more than 2 Amperes, fast-blow fuses should be incorporated into the wiring plan.
The module itself is protected against condensation water with a polymeric conformal coating. Supplementary soldering on any
solder pad will destroy the conformal coating and with it protection against condensation water.
If the IP rating of the fixture or channel letter system should be higher as IP22 the design of the housing should be according to the
IP standards. Operation in or under water is not allowed.

Assembly Information
Mounting of the LED module may be performed with screws or Snap-In spacer (e.g. from Richco www.richco-int.com) by using 4
mm holes in the circuit board.
The mounting of the module is carried out by attaching it at the mounting holes. Mounting screws should be treated with synthetic
washers to prevent circuit board damage and possible short circuiting.
A maximum of 3 Modules can be installed consecutively from any power feed. Installation with more than 3 BACKlight Modules
may take the form of, for example, either 6 Modules installed consecutively with a power feed to the centre or with a splitting of the
power feed to contact groups of 3 Modules.
To connect the LED Modules with each other or with OPTOTRONIC Power Supply we recommend standard clamps. (e.g. WAGO
243-214 or 224-201)
