Safety precautions

9/56

Safety precautions

The board must be used only by expert technicians. Due to the high voltage (220 V ac)

present on the parts which are not isolated, special care should be taken with regard to

people's safety.

There is no protection against high voltage accidental human contact.

After disconnection of the board from the mains, none of the live parts should be touched

immediately because of the energized capacitors.

It is mandatory to use a mains insulation transformer to perform any tests on the high

voltage sections (see circuit sections highlighted in Figure 7 and Figure 8) in which test

instruments like spectrum analyzers or oscilloscopes are used.

Do not connect any oscilloscope probes to high voltage sections in order to avoid damaging

instruments and demonstration tools.

Warning:

ST assumes no responsibility for any consequences which

may result from the improper use of this tool.
