Safety Notes
This section provides notes on using your US110 safely. Read this section carefully to ensure proper
and safe use of the US110. For symbols, see "SAFETY INDICATIONS" provided earlier.
General
WARNING
Do not use the US110 for services where critical high availability may directly
affect human lives.
Your US110 is not intended to be used with or control facilities or devices
concerning human lives, including medical devices, nuclear facilities and
devices, aeronautics and space devices, transportation facilities and devices;
and facilities and devices requiring high reliability. NEC assumes no liability for
any accident resulting in personal injury, death, or property damage if the
US110 has been used in the above conditions.
Do not use the US110 if any smoke, odor, or noise is present.
If smoke, odor, or noise is present, immediately turn off the US110 and
disconnect the power plug from the outlet, then contact your service
representative. Using the US110 in such conditions may cause a fire.
Keep needles or metal objects away from the US110.
Do not insert needles or metal objects into the US110. Doing so may cause an
electric shock.
CAUTION
Keep water or foreign matter away from the US110.
Do not let any form of liquid (water etc.) or foreign matter (e.g., pins or paper
clips) enter the US110. Failure to follow this warning may cause an electric
shock, a fire, or a failure of the US110. When such things accidentally enter
the US110, immediately turn off the power and disconnect the power plug
from the outlet. Do not disassemble the US110. Contact your service
representative.

v
Power Supply and Power Cord Use
WARNING
Do not hold the power plug with a wet hand.
Do not disconnect/connect the plug while your hands are wet. Failure to
follow this warning may cause an electric shock.
CAUTION
Plug in to a proper power source.
Use a wall outlet of specified voltage. Use of an improper power source may
cause a fire or a power leak.
Do not install the US110 where you need an extension cord. Use of a cord
that does not meet the power specifications of your US110 may heat up the
cord and cause a fire.
Do not connect the power cord to an outlet that has an illegal number of
connections.
The electric current exceeding the rated flow overheats the outlet, which may
cause a fire.
Insert the power plug into the outlet as far as it goes.
Heat generation resulting from a halfway inserted power plug (imperfect
contact) may cause a fire. Heat will also be generated if condensation is
formed on dusty blades of the halfway inserted plug, increasing the possibility
of fire.
Use the authorized power cord only.
Use only the power cord that comes with your US110. Use of an unauthorized
power cord may cause a fire when the electric current exceeds the rated flow.
Also, observe the following to prevent an electric shock or fire caused by a
damaged cord.
■Do not stretch the cord harness.
■Do not bend the power cord.
■Do not twist the power cord.
■Do not step on the power cord.
■Do not bundle power cords.
■Do not pinch the power cord.
■Keep chemicals away from the power cord.
■Do not place any object on the power cord.
■Do not alter, modify, or repair the power cord.
■Do not secure the power cord with staples or equivalents.
■Do not use any damaged power cord. (Replace a damaged power cord
with a new one of the same specifications. Ask your service representative
for replacement.)

vi
CAUTION
Do not use the attached power cord for any other devices or usage.
The power cord that comes with your US110 is designed aiming to connect
with this US110, and its safety has been tested. Do not use the attached
power cord for any other purpose. Doing so may cause a fire or an electric
shock.
Do not pull the cord harness to disconnect the power cord.
Hold the connector of the power cord and pull it straight. Pulling the cord
harness or applying excess force to the connector may cause a damage to
the cable, resulting in a fire or an electric shock.
Installation, Relocation, Storage, and Connection
CAUTION
Do not install the US110 in any place other than specified.
Do not install the US110 in the following places or any place other than
specified in this User's Guide. Failure to follow this instruction may cause a
fire.
■a dusty place
■a humid place such as near a boiler
■a place exposed to direct sunlight
■an unstable place
Do not use the US110 in the place where corrosive gases exist.
Make sure not to locate or use the US110 in the place where corrosive gases
(sulfur dioxide, hydrogen sulfide, nitrogen dioxide, chlorine, ammonia, ozone,
etc.) exist.
Also, do not place it in the environment where the air (or dust) includes
components accelerating corrosion (ex. sulfur, sodium chloride) or conductive
metals. There is a risk of a fire due to corrosion and shorts of an internal
printed board. Consult with your service representative for a place
appropriate to US110.

vii
Cleaning and Working with US110
WARNING
Do not disassemble, repair, or alter the US110.
Never attempt to disassemble, repair, or alter the US110 on any occasion
other than described in this manual. Failure to follow this instruction may
cause an electric shock or fire as well as malfunctions of the US110.
Disconnect the power plug before accessing inside the US110.
Make sure to power off the US110 and disconnect the power plug from a
power outlet before cleaning. Touching the inside of US110 with its power
cord connected to a power source may cause an electric shock even of the
US110 is off-powered.
Disconnect the power plug from the outlet occasionally and clean the plug
with a dry cloth. Heat will be generated if condensation is formed on a dusty
plug, which may cause a fire.
During Operation
WARNING
Avoid contact with the US110 during thunderstorms.
Disconnect the power plug from the outlet when a thunderstorm is
approaching. If it starts thundering before you disconnect the power plug, do
not touch any part of the US110 including the cables. Failure to follow this
warning may cause a fire or an electric shock.
Keep animals away from the US110.
Failure to follow this warning may cause a fire or an electric shock.

viii
For Proper Operation
Observe the following notes for successful operation of the US110. Use of the US110 ignoring the
notes will cause malfunctions or failures of the US110.
