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.
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.
Observe correct polarity!
Depending on the product incorrect polarity will lead to emission of red or no light. The module can be destroyed! Correct polarity
immediatelly! (see "reverse voltage", page 2)
Please ensure that the power supply is of adequate power to operate the total load.
When mounting on metallic or otherwise conductive surfaces, there needs to be an electrical isolation at soldering points between
module and the mounting surface.
The maximum length of a coherently operable unit is 9,9m.
By two-pole feed in the middle or from both ends the length can be doubled.
Pay attention to standard ESD precautions when installing the module.
If the module is supposed to be cut at X1, X2 or X3 (see techn. drawing) the following has to be respected:
- Take care for the correct orientation of the module: The power feed must come from the side indicated in the techn drawing.
- The module must not be cut before the first two LED, which have the Tc-Point in between them. This part would emit no light.
- To operate the desired subunits, the termination LF-2TERM must be applied. In analogy to LF-2PIN, push the termination over the o
contacts and and fix it.
The module, as manufactured, has no conformal coating and therefore offers no inherent protection against corrosion. The ability to
customize the length of the module by cutting at specifically marked points is a key feature of the product and hence the reason for no
factory installed conformal coating. For these reasons, it is recommended that the user complete all module modifications first (cutting
wiring) and then apply a conformal coating in the final stages of installation.
Damage by corrosion will not be honored as a materials defect claim. It is the user´s responsibility to provide suitable protection again
corrosive agents such as moisture and condensation and other harmful elements.
For applications involving exposure to humidity and dust the module must be protected by a fixture or housing with a suitable protectio
class. The module can be protected against condensation water by treatment with an appropriate circuit board grade conformal coatin
The conformal coating should have the following features:
- Optical transparency
- thermal expansion matching the thermal expansion of the module 15-30*10^-6 cm/cm/K
- low permeability of steam for all climatic conditions
- resistance against corrosive environment
To also ease the luminaire/installation approval, electronic control gear for LED or LED modules should carry the CE mark and be ENE
certified. In Europe the declarations of conformity must include the following standards:
CE: EC 61374-2-13, EN 55015, IEC 61547 and IEC 61000-3-2
ENEC: 61374-2-13 and IEC/EN 62384.
Also check for the mark of an independent authorized certification institute.
Please see the relevant brochure for more detailed information (see "Related and Further Information")
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.
In order to drive OSRAM LED-Modules safely, it is absolutely necessary to operate them with an electronically stabilised power
supply protecting against short circuits, overload and overheating.
OSRAM OPTOTRONIC® electronic control gear complies to all relevant standards and guarantees safe operation.
