may use safety related graphical symbols
as shown below to note safety requirements.
Lightning Bolt:
The lightning flash with
arrowhead symbol, within an equilateral triangle,
WARNING symbol, is intended to alert the user to
the presence of un-insulated
dangerous voltage
within the product’s enclosure that may be
sufficient in magnitude to constitute a risk of
electric shock to persons or domestic animals.
Exclamation Point:
The exclamation point
within an equilateral triangle, CAUTION symbol,
is in-tended to alert the user to the presence of
