Safety Precautions
Caution (for installation and connection)
Transportation, unpacking, and installation works must be carried out by
more than one person. Carry the unit considering its weight and
balance, and place it on a stable and robust base.
 Dropping or toppling the unit may cause injury.
 The approximate weight of the unit is 21kg.
 If you drop the unit, stop using it and have it inspected and repaired.
For repair, contact us.
Keep plastic package bags out of reach of children.
 Children may suffocate if they place their heads into plastic bags.
Make sure to connect the unit's AC input to a commercial power source
with rated input voltage (100 VAC - 120 VAC) and 50/60 Hz frequency.
 Connecting to a commercial power source with a different rated input voltage or
frequency 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. The socket-outlet shall be installed near the
equipment and shall be easily accessible (Be sure to pull out the AC
input plug from the power outlet.).
 When performing maintenance on the connected devices, follow the above
instructions 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.
Connect to a commercial power source having a capacity of 15A or
more.
To use the 15A plug (NEMA 5-15P) connected to the unit by factory
default, the maximum power capacity connectable to an output terminal
is approximately 1200VA or 1050W.
 If the unit is used at power consumption levels higher than the above, the input
current may become 15A or over, causing a heat or fire.
 If the indication "OL (Overload)" is displayed, change the plug to a 20A AC input
plug in the product package.
When changing the input cable, make sure to perform the connection as
specified.
Make sure to stop the primary power supply before connecting the unit
to the AC input terminal.
 There is a danger of an electrical shock or electric leak.
Provide secure grounding.
 Connect the terminal to a commercial power source and ground it. A failure or leak
that occurs when the unit is not properly grounded may result in electric shock.
