Safety precautions
Provide secure grounding.
● Connect the ground terminals of the UPS and the devices to be connected to the ground.
(Refer to "2. Installation and connection" on page 12.)
If a failure or leak occurs, it may cause an electric shock. Touching the UPS and other devices
without grounding at the same time may cause an electric shock.
● When you use the 3P-2P conversion Plug for the AC Input Plug, be sure to perform grounding
before connecting the AC Input Plug into a wall outlet (commercial power). On the other hand,
be sure to disconnect the AC Input Plug from a wall outlet (commercial power) before discon-
necting the grounding wire.
● Without grounding, the Power line surge protection and the Network line surge protection do
not work.
The installation orientation is designated. Do not install the product in
other orientations.
● Refer to "2-2 Installing the product" on page 14.
● Falling may cause injury.
Do not use the product where the maximum temperature exceeds 40°C.
● The battery becomes week rapidly, which may cause a fire.
● Doing so may cause a failure or malfunction of the UPS.
Concerning installation and storage of the products, follow the instructions
listed below.
● Do not install the product in a place where humidity is lower than 20% or higher than 90%.
● Do not use the product in a place where humidity is lower than 25% or higher than 85%.
● Do not install the products at a closed place such as in a cabinet without clearance, at a place
with flammable gas or corrosive gas exist and in the open air.
● Doing so may cause a fire.
Do not obstruct the air inlet and outlet in the side and rear of the product.
● Inside temperature increases, which may cause a failure of the UPS and the deterioration of
the battery.
● Install the product at least 5 cm from the walls.
Do not install the product on an unstable base.
● Dropping or falling may cause injury.
Connect the UPS to a wall outlet (commercial power) with a current capacity
larger than the maximum input current of the UPS.
● Otherwise, the power cord may be heated.
● When the equipment of the maximum capacity is connected, the maximum current that flows
is 8A for the BU50XS, 10A for the BU70XS and 14A for the BU100XS.
Be sure to connect the input plug of the UPS to a wall outlet (commercial
power) of 100 VAC (50/60Hz).
● Connecting it to a wall outlet (commercial power) of a different voltage may cause a fire.
● The UPS may fail.
