Safety precautions
vi
When an abnormality (unusual sound or smell) occurs, turn OFF the unit's
power switch and disconnect the AC input plug from the wall outlet.
Install the unit soon after the AC input plug is disconnected from the wall
outlet.
●
When performing maintenance on the connected devices, follow the above instructions to en-
sure safety.
Do not connect devices such as dryers, some solenoid valves, etc. ,
which have a half-wave recti
fi
er that allows only half-cycle AC power to
fl
ow through.
●
Overcurrent may damage the UPS.
The maximum output capacity cannot be used when using the AC input
plug that ships with the BN150S and BN300S (BN150S: 15A/NEMA5-15P,
BN300S: 30A/NEMAL5-30P).
●
Overheating or
fi
re may occur if the power consumption exceeds the limits shown in the “AC
input plug” table on page 16.
●
If the maximum output capacity is being used, replace the plug as described in the table on
page 13.
When changing the input cable for the BN150S/BN220S/BN300S, perform
connection as speci
fi
ed and make sure to properly match the AC input
terminal with the appropriate wire color.
●
Refer to “ AC input plug replacement procedure” 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 speci
fi
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.
Do not use the unit where the maximum temperature exceeds 40
°
C.
●
The battery deteriorates rapidly.
●
Doing so may cause a failure or malfunction of the unit.
Do not exceed the ranges speci
fi
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 the unit in places where the ambient temperature is lower than 0°C or higher than
40°C.
●
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 exposed to direct sunlight, places with large amounts of dust,
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 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.
