Safety precautions
Caution (for installation and connection)
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.
● This UPS utilizes voltages that may be hazardous. Do not attempt to disassemble the unit The
unit contains no user serviceable parts. Only factory service personnel may perform repairs.
● Connection to any other type of receptacle other than a two-pole,three-wire grounded recep-
tacle may result in shock hazard as well as violate local electical codes.
● Do not allow liquids or any foreign object to enter the UPS. DO not place beverages or any
other liquid-containing vessels on or near the unit.
● This unit intended for installation in a controlled environment (temperature controlled, indoor
area free of conductive contaminants). Avoid installing the UPS in locations where there is
standing or running water,or excessive humidity.
● Do not attach a power strip or surge suppressor to the UPS.
● Do not attach non-computer-related items,such as medical equipment,life-support
equipment,microwave ovens,or vacuum cleaners to UPS.
● With the installation of the equipment it should be prevented, that the sum of the leakage
current of the UPS and the connected consumer does not exceed 3.5mA.
Do not block the air vents on the unit. The BU1002SW has air vents on the
front, side and back, while the BU3002SW has air vents on the front and back.
● Doing so will cause the internal temperature to rise, which may cause the unit to fail and the
battery to deteriorate.
● Leave at least 5 cm of space between the vent and the wall.
Do not connect a standalone transformer such as a voltage transformer
or isolating transformer to the output side.
● Overcurrent may damage the UPS.
● There is no problem in connecting a transformer to the input side.
Do not connect devices that cannot be used with commercial power supply.
● 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 con-
nected devices.
Do not connect devices with rated voltage of 200 to 240 VAC or higher.
● The rated output voltage of this device is 200 to 240 VAC.
● Overcurrent may damage the connected devices.
When in use, make sure the output terminal block cover is attached.
Do not turn ON the power switch when it is detached.
● Voltage is applied to the output terminal block when the power switch is ON, which can result
in electric shock.
For PLUGGABLE EQUIPMENT, the socket-outlet shall be installer near
the equipment and shall be easily accessible.
