• Do not open the device when the power cord is connected. For sys-
tems 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 uti-
lized to power the device shall be within 10 feet (3 meters) of the
device, shall be easily accessible, and protected by a circuit
breaker in compliance with local regulatory requirements.
• For AC powered devices, ensure that the power cable used meets
all applicable standards for the country in which it is to be
installed.
• 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.
• WAN, LAN & PSTN ports (connections) may have hazardous volt-
ages 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 cau-
tion when working near these ports. When disconnecting cables
for these ports, detach the far end connection first.
