Caution
(for installation and connection)
Make sure to connect the unit’s AC input plug to a commercial power
source with rated input voltage (100 VAC) and 50/60 Hz frequency.

Connecting to a commercial power source with a different rated input voltage or fre-
quency may result in a fire.

The unit may fail.
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. Disconnect the AC input plug from the wall outlet.
The socket-outlet shall be installed near the equipment and shall be easily
accessible.

When performing maintenance on the connected devices, follow the above instruc-
tions to ensure safety.
Do not connect devices such as dryers, some solenoid valves, etc., which
have a half-wave rectifier that allows only half-cycle AC power to flow
through.

Overcurrent may damage the UPS.
Do not connect the maximum load when using the default AC plug with
BN150T or BN300T. (The default plug of BN150T: 15A/NEMA5-15P,
BN300T: 30A/NEMA L5-30P)

If the power consumption exceeds the limits shown in the table in "2-3 Connecting the
AC input", overheating or fire may occur.

If the maximum output capacity is being used, replace the plug as described in the
table in "2-3 Connecting the AC input".
When changing the input cable for the BN150T/BN220T/BN300T, perform
connection as specified.
Make sure to properly match the AC input terminal with the appropriate
wire color.
Do not perform work on the AC input terminal while the unit is connected
to a commercial power source.

Use an input cable that complies with the input current specification of the UPS.

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 fire.
Do not install the unit in other than specified orientations.

Dropping or toppling the unit may cause injury.

If you install the unit in an orientation other than specified, the unit cannot be protected
from a battery fluid leakage.

Caution
(for installation and connection)
Do not use the unit where the maximum temperature exceeds 40°C.
l
The battery deteriorates rapidly.
l
Doing so may cause a failure or malfunction of the unit
Do not exceed the ranges specified for environmental conditions during
use/storage.
Do not install or store the unit in the places listed below.
l
Do not store in places where the humidity is lower than 10% or higher than 90%.
l
Do not use the unit in places where the ambient temperature is lower than 0°C or
higher than 40°C. (With no condensation)
l
Do not use in places where the humidity is lower than 25% or higher than85%
l
Do not install/store the unit in closed places such as cabinets with no clearance,
places where there is flammable or corrosive gas, places with large amounts of dust,
places exposed to direct sunlight, places exposed to shock or vibration, salty or wet
places, or outdoors.
l
Installation or storing the unit in such a place may cause a fire.
When you use plug strip and other plugs to connect additional devices, do
not connect devices that exceed the current capacity of the available plugs.
l
The current protection of the unit may operate, which may stop the output.
l
The wiring of the plug strip heats up, which may cause a fire.
Do not pinch or sharply bend the cable.
Do not fold or knot the cable.
l
Doing so may cause the cable to be damaged or heated, which may cause an electric
shock or a fire.
l
If the cable is damaged, stop using the unit and have the cable repaired.
l
For repair, contact the shop of purchase.
All of the included accessories are designed to be used with the unit. Do
not use the accessories with other devices.
l
Doing so may compromise the safety of devices.
Do not block the air vents (front, rear, and sides).
l
Doing so will cause the internal temperature to rise, which may cause the unit to fail
and the battery to deteriorate.
l
Leave at least 5 cm of space between the vent and the wall.
Do not connect a transformer such as a voltage transformer or isolating
transformer to the output side.
l
Overcurrent may damage the UPS or cause it to malfunction.
l
Even when connected to the input side, the UPS may fail or malfunction. Make sure to
check the operation before use.
Do not connect devices that cannot be used with commercial power supply.
l
When the unit’s power switch is turned ON and an error occurs with the connected
device, bypass operation is performed and commercial power supply is supplied as is
to the connected devices.
Do not exceed the ranges specified for environmental conditions during
use/storage.
