4.

Connect the two combined neutral black wires to the mains supply neutral and, lastly,

connect J6 from the FSC board to live of the mains supply.

5.

Ensure that all parts of the FSC PCB and connection wires are well isolated from any

conducting surfaces such as metal parts, etc. to avoid accidental shock hazard or

damage to the circuit.

6.

Once the switch is turned on, ensure that no part of the PCB is touched using bare

hands or metallic objects.

7.

The fan speed can now be changed using the IR remote transmitter unit or using the

tactile switches provided onboard. When using the onboard tactile switches, kindly

ensure that no direct body contact is made with the circuit (use safety gloves).

8.

The microcontroller can be programmed over the SWIM interface using an ST-Link or

R-Link programming tool. When doing so, the circuit should be completely

disconnected from the mains supply and powered using the +5 V supply from an R-

Link or an external +5 V power supply.
