1. The LED module itself and all its components shall not be subjected to mechanical stress and assembly must not damage or destroy conducting paths on
the circuit board.
2. Observe correct electrical polarity, incorrect polarity may destroy the module. (Depending on the product, incorrect polarity may lead to emission of red or
no light.)
3. Ensure the power supply is of adequate power to operate the total load.
4. Electrostatic Discharge (ESD) precautions shall be incorporated when handling or installing the module. (For more information, reference document
# LED093 ESD Protection for LED Systems.)
5. Installation of LED modules shall be made with regard to all applicable electrical and safety standards. Only qualified personnel should be allowed to
perform installations.
6. Modules may be hot to the touch. Use caution when handling.
7. Damage by corrosion and improper heat sinking will not be honored as a materials defect claim. It is the user’s responsibility to ensure adequate heat sink
and protection against corrosive agents such as moisture, condensation and other harmful elements.
8. Avoid looking directly into the light beam as the high brightness may damage eyes.
9. 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 modification first (cutting, wiring) and then apply a conformal coating in the final
stages of installation.
WARNING: ONLY QUALIFIED PERSONNEL SHOULD PERFORM INSTALLATION. TO AVOID ELECTRICAL SHOCK OR COMPONENT DAMAGE, DISCONNECT
POWER BEFORE ATTEMPTING INSTALLATION OF THE POWER SUPPLIES AND/OR MODULES.
Failure to install the power supplies and/or LED modules in accordance with the National Electric Code (NEC), all applicable Federal, State and local electric codes as well
as the specific Underwriters Laboratories (UL) safety standards for the installation, location and application may cause serious personal injury, death, property
damage and/or product malfunction.
Safety Information
Assembly Information
1. The LINEARlight FLEX® POWER FLEX must be mounted on an appropriate metal heat sink.
2. The Smallest Electrical Unit can be removed by cutting with scissors before or after the designated solder pad.
3. The module may also be cut at points X1 or X2 (reference “Assembly Diagram” for locations). The following must be observed when making cuts at
these locations:
a. Observe the correct orientation of the module: The power feed must come from the side indicated in the technical drawing.
b. The module must not be cut before the first two LEDs, which have the Tc Point in between them. This part would emit no light.
c. To operate the desired subunits, the termination LF-2TERM must be applied. Disengage the terminations locking mechanism, slide it over
the open contacts and press the locking mechanism back in place.
4. The mounting of the module is facilitated by means of the double-sided adhesive on the back-surface of the module. Care must be taken to provide a clean
and dry mounting surface, free of oils or silicone coatings as well as dirt particles. The mounting substrate must have sufficient structural integrity. Take care
to completely remove the adhesive backing. Once the module is appropriately positioned, press on the module with about 20N/cm2 (refer to application
techniques of 3M adhesive transfer tapes).
5. Solder connections should only be performed on designated solder pads (marked “24V +/-”). During soldering, do not exceed the maximum
soldering time of 10 seconds and the maximum soldering temperature of 260°C.
6. Connecting soldered wires to an un-mounted module: Solder pads must not be pre-tinned. However, the wires must be pre-tinned at a max. 4 sec. at 300°C.
Allow solder points to completely cool down before performing the next soldering. Prevent shear, or peel forces.
7. Connecting soldered wires to a module mounted on a heat sink: Pre-tin solder pads and wires and solder for max. 3 sec. at 350°C. Allow
solder points to completely cool down before performing the next soldering. Prevent shear, or peel forces.
8. For applications involving exposure to humidity and dust, the module must be protected by a fixture, or housing with a suitable protection class.
9. The module can be protected against condensation by treatment with an appropriate circuit board grade conformal coating. The conformal coating should have
the following features:
a. Optical transparency
b. UV – resistance
c. Thermal expansion matching the thermal expansion of the module 15-30 x 10^-6cm/cm/K
d. Low permeability of steam for all climate conditions
e. Resistance against corrosive environment
Note: Since this module’s connectors are “Dry Location Only” rated, they must not be used as a connection means when conformal coating becomes necessary.
Soldered wires are the appropriate connection means used in conjunction with conformal coating. Any of the necessary steps 2, 3, 5, 6, & 7 must be completed
before conformal coating can be applied.
