●
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 plug to a commercial power
source with rated input voltage (100 V AC) and 50/60Hz frequency.
●
Connecting to a wall outlet (commercial power) with a different voltage or frequency may result
in a fi re.
●
The unit may fail.
When an abnormality (unusual sound or smell) occurs, turn OFF the unit's
power switch and disconnect the AC input plug from the wall outlet.
Install the unit soon after the AC input plug is disconnected from the wall
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 rectifi er that allows only half-cycle AC power to fl ow through.
●
Overcurrent may damage the UPS.
Connect the unit to a wall outlet (commercial power) with a capacity of 4.8A
or more for BY35S, 6.5 A or more for BY50S, , 12.0 A or more for BY80S
and 15.0 A or more for BY120S.
●
Otherwise, the power cord may be heated.
●
When equipment with the maximum output capacity is connected, a maximum current of 4.8 A (BY35S),
6.5 A (BY50S), 12.0 A (BY80S) or 15.0 A (BY120S).
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 fi re.
Do not install the unit in other than specifi ed orientations.
●
Dropping or toppling the unit may cause injury.
●
If you install the unit in an orientation other than specifi ed, the unit cannot be protected from a battery
fl uid leakage.
Do not use the unit where the maximum temperature exceeds 40
°
