Indicates areas of equipment where AC line voltages are used
and present a potential risk of electrocution. Areas using line voltages should not be
accessed during operation.
AC-to-DC Power Supply:
Indicates AC line voltages are used and present on portions
of the power supply, including the heat sinks. A potential risk of electrocution exists.
Areas using line voltages should not be accessed during operation.
