2. Safety warning

The SSL5301DB1215 demo board input is connected to the 120 V mains. Avoid touching

the board while it is connected to the mains voltage and when it is in operation. An

isolated housing is obligatory when used in uncontrolled, non-laboratory environments.

Galvanic isolation from the mains phase using a fixed or variable transformer is always

recommended. Figure 1

shows the symbols that identify these devices.
