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 weights of the units are 28kg (BU2002RWLG), 33kg (BU3002RWLG) and 61kg
(BU5002RWLG).
●
If you drop the unit, stop using it and have it inspected and repaired.
For repair, contact Omron representatives.
Do not hold the side of the front panel when lifting.
●
Injury may result if the panel comes off and falls.
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 (200/208/220/230/240VAC) and 50/60Hz
frequency.
●
Connecting to a commercial power source with a different rated input voltage or frequency may
result in a fire.
●
The unit may fail.
For BU5002RWLG, when an abnormality (unusual sound or smell) occurs,
disconnect the AC input plug from the wall outlet, or turn OFF the INPUT
PROTECTION switch (input overcurrent protection switch) on the back of
the unit. The socket-outlet shall be installed near the equipment and shall
be easily accessible.
For BU2002RWLG and BU3002RWLG, turn OFF the external breaker
installed on the input side.
●
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 the unit to a wall outlet (commercial power) with the
appropriate capacity (11A or greater for BU2002RWLG, 16A or greater for
BU3002RWLG and 27A or greater for BU5002RWLG).
●
Otherwise, the power cord may be heated.
●
When equipment with the maximum output capacity is connected, a maximum current of 11A
(BU2002RWLG), 16A (BU3002RWLG), or 27A (BU5002RWLG) flows.
When changing the input cable, make sure to perform the connection as
specified.
●
When connecting a cable to the terminal block, use a cable that complies with the input current
specification of the UPS.
●
Failure to do so may result in electric shock or ground fault.
