Safety notes
General
WARNING
Do not use US310e for services which may directly affect human
lives and that critically high reliability is required.
Your US310e 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 US310e
has been used in the above conditions.
Do not use US310e if any smoke, odor, or noise is present.
If smoke, odor, or noise is present, immediately turn off US310e
and disconnect the power plug from the outlet, then contact your
maintenance service representative. Using US310e in such
conditions may cause a fire.
Do not insert needles or metal objects.
Do not insert needles or metal objects into ventilation holes or
the USB connector. Doing so may cause an electric shock.
CAUTION
Keep water or foreign matter away from US310e.
Do not let any liquid such as water or foreign materials including
pins or paper clips enter US310e. Failure to follow this warning
may cause an electric shock, a fire, or failure of US310e. When
such things accidentally enter US310e, immediately turn off the
power and disconnect the power plug from the outlet. Do not
disassemble US310e, and contact your maintenance service
company.
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 proper wall outlet with the specified voltage. Use of an
outlet with a voltage other than that specified may cause a fire or
an electric leakage.
Do not install US310e in any environment that requires an
extension cord. Connecting to an outlet that does not meet the
power specifications of US310e causes overheating, resulting in a
fire.
Do not connect many power cords into a single outlet by using
extension cords.
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 and causes the short
circuit. The heat may result in fire.
Use the authorized power cord only.
Use only the power cord that comes with US310e. Use of an If an
electric current exceeding the rated current flows, it could cause a
fire.
Also, observe the following precautions 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.
Uncoil the power cord before use.
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 a damaged power cord. (Replace a damaged power
cord with a new one of the same specifications. Ask your
maintenance service representative for replacement.)
