Caution about Safety
v
Damage Do not use the UPS for the uses that may hurt the human
body or exert an important influence on the society and
public.
Medical instrument affecting human life directly
Device that may hurt the human body
Socially and publicly important computer system
Do not put an object (display or floppy disk etc.)
vulnerable to magnetism around the UPS.
There is fear of exerting a bad influence on the object.
Confirm that the voltage set up by the switch of voltage
setting is within the range of input voltage of the
connection device.
There is fear of damaging the connection device.
Do not operate the switch of voltage setting during
operation of the UPS.
There is fear of damaging the connection device, since the changed
voltage is outputted at the restart. And even if operating the switch
during operation of the UPS, the output voltage cannot be changed.
Replace the battery periodically.
If continuing to use the UPS that the battery life ended, there is fear
of a liquid leak of battery, a smoking, and an ignition.
Replace the battery with one specified by our company
and a new one.
If using the un-specified battery or mixing an old battery and a new
battery, it becomes the cause of a liquid leak of battery, a smoking,
an ignition, and the UPS failure and trouble.
When performing the rolling blackouts or when cutting off
an input power supply, perform them after stopping the
operation of the UPS, with reference to Chapter 4.2
"Turning off the UPS". The stop of operation can be
confirmed by slow blink (in the cycles of approximately
1.6 sec.) of the RUN LED (green).
If cutting off an input power supply when the UPS is operating (the
RUN LED is lighting), the UPS switches to the battery operation
since it will be in the same state as a power failure.
Performing such unnecessary battery operation leads to a shortening
of a cycle of battery replacement.
Warning label
Warning labels are attached to the UPS.
Never remove the labels.

Do not perform the battery check in succession.
When the battery check is performed, the UPS temporarily switches to the battery
operation.
If the battery check is performed in succession, there is fear of the battery deterioration
or a shortening of a cycle of battery replacement since the battery becomes an
over-discharge state.
If the UPS is not used for a long time, charge the battery every two
months.
The battery is charged by operating the UPS.
For the battery charging time, refer to Chapter 8.1 "Rated Specification".
If the UPS is left without operating for a long time, there is a possibility that the UPS get
unusable since the battery becomes an over-discharge state due to self-discharge.
This UPS is recyclable.
This UPS uses the small sealed lead storage battery. The small sealed lead storage
battery uses expensive and rare resources. However, these precious resources are able to
recycle. Cooperate in recycling without disposing of the used battery.
Do not block the vent hole and cooling fan or use the UPS in a stuffy place.
The vent hole and cooling fan are equipped in order to cool the inside of the UPS.
There is a possibility that the inside and ambient temperature of the UPS may get out of
the rated specification.
Replace the cooling fan periodically.
If continuing to use the UPS that the cooling fan life ended, there is a possibility that the
inside temperature of the UPS may get out of the rated specification.
Do not use 5 to 9 of the switch of voltage setting.
It becomes impossible for the UPS to start up normally.

Caution for Use
vii
The permissible voltage between the input electric cable of the UPS and
the ground is 250V AC.
If the voltage more than 250V AC is applied, the filter circuit of the input part may be
damaged.
The permissible input surge voltage of the UPS is 5kV peak (1.2 50µs).
However, if the model of the UPS is "-UC" and "-C", it is 2kV peak (1.2 
50µs).
If the surge voltage more than 5kV peak ("-UC" and "-C" are 2kV peak) is applied, the
filter circuit of the input part may be damaged.
The input voltage of the UPS is 160 to 288V AC.
When input voltage is different from the rated specification (400V AC etc.), install a
transformer at the outside of the UPS to convert voltage. If the voltage more than the
range of the input voltage is applied, the UPS may be damaged.
Pay attention to an input voltage.
This UPS can operate up to 288V AC. However, an input voltage of the general device is
200V AC ±10%. Therefore, if switching to the bypass operation when applying the
voltage of 220V AC to the UPS, the voltage exceeding specification is applied to the
connection device. Adjust the input voltage to the specification of connection device.
Do not apply single-line grounding on the output side.
Between the input and output of the UPS is not insulated. Therefore, do not apply
single-line grounding on the output side.
There is fear of becoming the cause of the trouble of connection device by noise or the
failure.
When connecting the UPS to the electrical power equipment with the earth
leakage breaker, select the earth leakage breaker not to trip due to current
leakage.
When connecting the UPS to the electrical power equipment with the earth leakage
breaker, select the earth leakage breaker in consideration of total number of current
leakage of the UPS plus current leakage of the connection device.
When connecting the UPS to a three-phase power supply system, be sure
to connect the grounding phase of the three-phase power supply system
to the electrode of a grounding side of the AC input of the UPS.
If connecting to an un-grounding power supply, there is fear of becoming the cause of
the malfunction.

Caution for Use
viii
When using a generator temporarily during the rolling blackouts, use a
generator satisfying the following specification.
If connecting a generator not satisfying the following specification to the input part of
the UPS, there is a possibility of becoming the cause of the malfunction or damage of the
UPS.
Voltage regulation: depend on the input specification of the connection device
Frequency variation: within rated frequency ± 5% (frequency does not change
rapidly)
Voltage waveform distortion: within 5%
