2 Safety warning

The board must be connected to mains voltage. Avoid touching the demo board while

it is connected to the mains voltage. An isolated housing is obligatory when used in

uncontrolled, non-laboratory environments. Galvanic isolation of the mains phase using

a variable transformer is always recommended.

Figure 3

shows the symbols that identify

the isolated and non-isolated devices.
