Cautions 2. When performing debugging with the on-chip debug function, be careful of the positions and
timing for step executions and breaks. Stopping the PFC circuit or Buck converter abruptly
may damage the circuit elements on the board due to overvoltage or overcurrent, resulting in
smoke or fire in the worst case. Especially, do not set any break for the Peripheral Break
function because it stops the timer for PFC and Buck converters upon a break.
Do not touch to the high voltage area of the board.
Touching the board by tools or body while power is being supplied cause product failure or electric
shock.
Do not touch with wet hands.
Doing so cause product failure or electrical shock.
Do not turn on the power switch in insufficient state of each cable connection such as AC
power cable, LED connection cable and interface cable.
Doing so may cause product failure, generation of heat, fire or electric shock.
Confirm the outlet is near this board and easily unplugged.
If smoke or an abnormal smell or sound is emitted or heating occurs, promptly switch off the
board power and unplug from AC power supply.
Using the board in such a state poses a risk of fire, burning or electric shock.
