Due to the special conditions of the manufacturing processes of LED the typical data of technical parameters can only reflect statistical figures and do not necessarily
correspond to the actual parameters of each single product which could differ from the typical data.
+) Preliminary Data
Technical Features

Cut into operable subunits at regular intervals
Mounting hole (Ø 4 mm) allows easy installation
with screws or standard circuit board support
hardware
Parallel connection up to two LED chains with
power feed in the centre of one OT 50W
Only parallel connection allowed
Conformal coating protects against
condensation water

Safety Information
The LED module itself and all its components must not be mechanically 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.
The LED Module incorporates no protection against short circuits, overload or 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".
OSRAM OPTOTRONIC ® power supplies are specifically designed with protection features for safe operation.
When using 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
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.
Observe correct electrical polarity!
For all W3 / W3F types (except LM10P / LD06A / DC02A) wrong polarity will lead to emission of red light. Attention, the module
can be destroyed! Correct polarity immediately!
For all other types, including LM10P / LD06A / DC02A), wrong polarity will lead to no light emission only (see also reverse voltage,
page 2)
Parallel connection is highly recommended as safe electrical operation mode.
Serial connection is not recommended. Unbalanced voltage drop can cause hazardous overload and damage the LED module.
Detach each circuit board unit of the LED-chain exclusively by cutting the connecting cables.
Electrical contact is achieved with the contact cables. A maximum of one LED-chain can be installed with power feed from one
end. Operation with more than one consecutive LED-chain, power feed from one end only, will reduce photometric performance
and exceed the current carrying capacity of the LED-chains.
Installation with more than one LED-chain on one OPTOTRONIC® 50W has to be realised by either feeding the power to the
centre or by splitting the power feed to contact groups of single LED-chains.
When using power supplies other than OPTOTRONIC® the maximum number of LED-chains on one 50 W power supply is: 2 for
white and 2,4 for blue and green. Otherwise overloading may occur.
The LED-chain can typically survive transient current levels of up to 3 Amperes. As a general design precaution, if the maximum
output current of the power supply is more than 3 Amperes, fast-blow fuses should be incorporated into the wiring plan.
If BL04 and OPTOTRONIC® class 1 power supply (e.g. OT50E) is being assembled on a metal grounded surface, use plastic
screws or plastic connectors to fix BL04. Otherwise the LED-system does not fulfil SELV requirements.
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 is required to be higher than 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-chain may be performed with screws or snap-in spacer (e.g. from Richco www.richco-int.com) by using Ø 4
mm holes in the circuit board.
The mounting of the LED-chain 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.
To connect the LED-chain with each other or with OPTOTRONIC® Power Supply we recommend standard clamps. (e.g. WAGO
243-214 or 224-201)
