Safety precautions
vi
When an abnormality (unusual sound or smell) occurs, turn OFF the
unit’s power switch to stop the output, and stop the supply of commercial
power.
For the BU75RW/BU100RW, disconnect the AC input plug from the wall
outlet. For the BU200RW/BU300RW, disconnect the AC input plug from
the wall outlet (commercial power) or turn OFF the INPUT PROTECTION
switch (input overcurrent protection switch) on the back of the unit.
●
When performing maintenance on the connected devices, follow the above instructions to
ensure safety.
Do not connect devices such as dryers, some solenoid valves, etc. ,
which have a half-wave rectifi er that allows only half-cycle AC power to
fl ow through.
●
Overcurrent may damage the UPS.
Connect the unit to a wall outlet (commercial power) with the appropriate
capacity (10A or greater for BU75RW, 12A or greater for BU100RW, 24A or
greater for BU200RW, and 35A or greater for BU300RW).
●
Otherwise, the power cord may be heated.
●
When equipment with the maximum output capacity is connected, a maximum current of 10A
(BU75RW),
12A (BU100RW), 24A (BU200RW) or 35A (BU300RW)
fl
ows.
When using the 15A plug (NEMA 5-15P) that is connected to the BU200RW
at shipment, the maximum capacity connectable to the output is
approximately 1100VA/880W.
●
When the power consumption exceeds this capacity, the input voltage becomes larger than 20A,
which may lead to overheating or
fi
re. .
●
If the “overload” display appears, switch to a 30A plug or connect to a power switchboard with a
power capacity of 24A or more.
When using the 30A plug (NEMA L5-30P) that is connected to the
BU300RW at shipment, the maximum capacity connectable to the output
is approximately 2400VA/1920W.
●
When the power consumption exceeds this capacity, the input voltage becomes larger than 30A,
which may lead to overheating or
fi
re.
●
If “OVER LOAD” is displayed, connect to a power switchboard with a power capacity of 35A or
more.
When changing the input cable for the BU200RW and BU300RW, make
sure to perform the connection as specifi ed. Make sure to properly match
the AC input terminal with the appropriate wire color.
Do not perform work on the AC input terminal while BU300RW is
connected to a commercial power source.
●
Refer to “2-4 Connecting the AC input” on page 16.
●
Failure to do so may result in electric shock or ground fault.
Provide secure grounding.
●
After checking the plug shape of the 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.
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 speci
fi
ed, the unit cannot be protected from a
battery
fl
uid leakage.
●
Use the included vertical stand when positioning the unit vertically.
