(4) When the installation and connection is complete, connect the AC Input Plug of the UPS to
a wall outlet (commercial power).
<BU150SW>
● The BU150SW comes equipped with a 15A input plug (NEMA 5-15) at shipment.
If this plug is used, make sure the capacity of the connected devices stays below the maxi-
mum capacities shown in the table below.
● When the "15A input exceeded" display appears (
cator), do not continue using the unit with the 15A input plug. Replace the input plug with the
included 20A plug.
When a 15A plug (NEMA5-15P) is used with BU150SW, the maximum
capacity connectable to output is approximately 1100VA/950W.
● When the power consumption exceeds this capacity, the input voltage becomes larger than
15A, which may lead to overheating or fi re.
● When the "15A input exceeded" display appears, replace the input plug with the 20A input
plug.
● When the AC input is connected directly from a power switchboard, make sure that the wir-
ing work is performed by a qualifi ed electrical engineer (with Type II certifi cation or higher).
To use with up to 1500VA/1050W, a wiring capacity of 20A or more is required.
(Recommended cable: nominal cross-section of 3.5mm
Input plug Maximum output capacity
15A plug Up to 1100VA/950W
20A plug Up to 1500VA/1050W
● Using a 15A plug
•
It is possible to use a wall outlet (commercial power) with a basic 15A (NEMA 5-15) plug.
•
It is possible to connect to a 2-pin outlet using the included 3P-2P adapter.
In this case, make sure the grounding is connected separately.

● Using a 20A plug
The maximum usable capacity is the rated output capacity of the BU150SW.
•
Provide a wall outlet (commercial power) suitable for the shape of the 20A plug (NEMA
L5-20).
•
Replace the AC input plug of the BU150SW with the included NEMA L5-20 plug.

● If the input current exceeds 15A, replace the plug with the 20A plug that was included
with the unit.
Changing the AC input cable
(1) Disconnect the 15A plug.
(2) Connect the NEMA L5-20 plug as shown in the diagram on the right.
Make sure that the wire colors match those in the diagram before
tightening the screw.
The maximum output capacity that can be connected is determined
according to the settings of the setting switches. (See the table above.)
Turn OFF setting switch 8 when using a 15A plug, and turn it ON when using
a 20A plug.
Malfunction occurs when the maximum output capacity is exceeded.
