## **LEDset interface** 

LEDset allows to control the output current of the control gear (ref. to LEDset application note). The input voltage of the Vset pin defines the output current relative to the maximum nominal current of the control gear. LEDset interface is not isolated to the secondary side of the LED driver output.

The relation between input voltage and output current is as following: 

**==> picture [353 x 206] intentionally omitted <==**

**----- Start of picture text -----**<br>
700mA<br>600mA<br>500mA<br>400mA<br>300mA<br>200mA<br>100mA<br>OFF<br>1V 3V 5V 7V 9V 11V<br>Vset<br>Iout<br>Protection region<br>**----- End of picture text -----**<br>


Output current relative to the nominal current Iout [% of Imax]=(Vset-1V)/(10V-1V) between Imin and Imax 

## **LEDset and DIPswitch** 

The output current could also be set in combination with the DIPswitch current pre-selection (350,500 and 700mA) and the LEDset interface. In those three operation modes the ECG does not switch off as soon as Vset exceeds 11V (no protection region).

**Earth connection** 

Earth connection is not required but may be used to improve EMI performance of the installation 

## **Wrong wiring** 

This control gear is inherently protected against wrong wiring. The wrong connections between LED+ with Vset and GNDset could damage irreversibly the ECG. All the other wrong wirings on the secondary side, once removed, make the ECG work regularly. LED- and GNDset terminals cannot be connected together. 

## **Installation notes** 

The luminaire manufacturer is responsible for providing the required clearances and creepage distances and also for the protection against electrical shock, especially for the line and load wires according EN 60598. 

## **Instruction sheet** 

Please consult the instruction sheet for further important information on e.g. wire stripping and wiring limitations in system installations. The instruction sheet is enclosed with the device or available upon request.
