systems without a power switch and without an external power
adapter, line voltages are present within the device when the
power cord is connected.
•
For devices with an external power adapter, the power adapter
shall be a listed Limited Power Source The mains outlet that is
utilized to power the device shall be within 10 feet (3 meters) of
the device, shall be easily accessible, and protected by a circuit

For AC powered devices which have 3 conductor power plugs
(L1, L2 & GND or Hot, Neutral & Safety/Protective Ground),
the wall outlet (or socket) must have an earth ground.
•
For DC powered devices, ensure that the interconnecting cables
are rated for proper voltage, current, anticipated temperature,
flammability, and mechanical serviceability.

voltages present regardless of whether the device is powered
ON or OFF. PSTN relates to interfaces such as telephone lines,
FXS, FXO, DSL, xDSL, T1, E1, ISDN, Voice, etc. These are
known as “hazardous network voltages” and to avoid electric
shock use caution when working near these ports. When dis-
connecting cables for these ports, detach the far end connection
first.
