➢TECHNICAL NOTES
Installation:
•Installation and maintenance must be performed only by qualified personnel in compliance with current regulations.
•The product must be installed inside an electrical panel protected against overvoltages.
•The product must be installed in a vertical or horizontal position with the cover / label upwards or vertically; Other positions are not
permitted. It is not permitted to bottom-up position (with the cover / label down).
•Keep separated the circuits at 230V (LV) and the circuits not SELV from circuits to low voltage (SELV) and from any connection with this
product. It is absolutely forbidden to connect, for any reason whatsoever, directly or indirectly, the 230V mains voltage to the bus or to
other parts of the circuit.
Power supply:
•For the power supply use only a SELV power supplies with limited current, short circuit protection and the power must be dimensioned
correctly. In case of using power supply with ground terminals, all points of the protective earth (PE = Protection Earth) must be
connected to a valid and certified protection earth.
•The connection cables between the power source "low voltage" and the product must be dimensioned correctly and they should be
isolated from every wiring or parts at voltage not SELV. Use double insulated cables.
•Dimension the power supply for the load connected to the device. If the power supply is oversized compared with the maximum
absorbed current, insert a protection against over-current between the power supply and the device.
•For the constant current output, the voltage of LED module (Vf) must be less of 5V at the voltage of power supply.
Command:
•The length of the connection cables between the local commands (N.O. Push button or other) and the product must be less than 10m;
the cables must be dimensioned correctly and they should be isolated from every wiring or parts at voltage not SELV. Use double
insulated shielded and twisted cables.
•All the product and the control signal connect at the local command (N.O. Push button or other) must be SELV (the devices connected
must be SELV or supply a SELV signal)
Outputs:
•The length of the connection cables between the product and the LED module must be less than 10m; the cables must be dimensioned
correctly and they should be isolated from every wiring or parts at voltage not SELV. Is preferable to use shielded and twisted cables.

4- On the screen will appear a box to name the strip led or spotlight controlled by DALCNET BLE device.
For ex.: you can name 'kitchen' the light in the kitchen, and 'living' the one in the living room. This is a simple way to control the lights in your
house.
5- DALCNET device has now been correctly paired and ready for use.
You will see the lamp name on the display. Here you can start controlling your led light.
