Safety precautions
iv
Connect the unit to a wall outlet with the proper current capacity, as
follows: 8A or more (BU50SW), 10A or more (BU75SW), 12A or more
(BU100SW), or 16A or more (BU150SW).
●
Otherwise, the power cord may be heated.
●
When equipment with the maximum output capacity is connected, a maximum current of
8A (BU50SW), 10A (BU75SW), 12A (BU100SW), or 16A (BU150SW) fl ows.
Provide secure grounding.
●
For a 3P wall outlet, directly connect the AC input plug of the unit to it. A failure or leak that
occurs when the unit is not properly grounded may result in electric shock.
●
When you use a 3P-2P conversion plug for AC input plug, be sure to perform grounding
before connecting the AC input plug into a wall outlet (commercial power).
Do not disconnect the grounding before disconnecting the AC input plug from a wall outlet
(commercial power).
Do not disassemble, repair, or modify the unit.
●
Doing so may cause an electric shock or a fi re.
Do not install the unit in other than specifi ed orientations.
●
Dropping or toppling the unit may cause injury.
●
If you install the unit in an orientation other than specifi ed, the unit cannot be protected from
a battery fl uid leakage.
Do not use the unit where the maximum temperature exceeds 40
°
C.
●
The battery becomes weak rapidly, which may cause a fi re.
●
Doing so may cause a failure or malfunction of the unit.
Do not exceed the ranges specifi ed for environmental conditions during
use/storage.
Do not install or store the unit in the places listed below.
●
Do not store in places where the humidity is lower than 10% or higher than 90%.
●
Do not use in places where the humidity is lower than 25% or higher than 85%.
●
Do not install/store the unit in closed places such as cabinets with no clearance, places
where there is fl ammable or corrosive gas, places with large amounts of dust, places ex-
posed to direct sunlight, places exposed to shock or vibration, or outdoors.
●
Installation or storing the unit in such a place may cause a fi re.
Do not connect equipment that exceeds the output capacity of the
unit. You can use a plug strip to connect additional devices, but do not
connect devices that exceed the current capacity of the plug strip.
●
The current protection of the unit may operate, which may stop the output.
●
The wiring of the plug strip heats up, which may cause a fi re.
Do not pinch or sharply bend the cable.
Do not fold or knot the cable.
●
Doing so may cause the cable to be damaged or heated, which may cause an electric shock or a
fi re.
●
If the cable is damaged, stop using the unit and have the cable repaired.
For repair, contact us; ____
All of the included accessories are designed to be used exclusively with
the unit. Do not use the accessories with other devices.
●
Doing so may compromise the safety of devices.
