Safety When Working With Electricity
WARNING
• This device contains no user serviceable parts. This
device can only be repaired by qualified service person-
nel.
• Do not open the device when the power cord is con-
nected. For systems without a power switch and without
an e
xternal 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 breaker in compli-
ance 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 hazard-
ous voltages present regardless of whether the device is
po
wered 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 volt-
ages” and to avoid electric shock use caution when
w
orking near these ports. When disconnecting cables for
these ports, detach the far end connection first.
• Do not work on the device or connect or disconnect
cables during periods of lightning activity.
