Getting started
Any measurement equipment must be isolated from the mains before powering the board.
To use an oscilloscope with the demonstration board, it is safer to isolate it from the AC line.
This prevents electric shocks which can occur as a result of touching any single point in the
circuit, but does not prevent shocks when touching two or more points in the circuit.
There is no insulation varnish on solder points. Care should be taken when performing
measurements (for example, voltage probes must be connected only when the line and the
power supply voltages are removed).

J1
The demonstration board is not electrically isolated from the
AC input. The MCU is directly linked to the mains voltage. No
insulation is ensured between the accessible parts and the
high voltage. The STCC08 demonstration board must be used
with care and only by persons qualified to work with
electricity at mains voltage levels.
