Check system operation beforehand if the unit is used in combination with a
device whose power supply voltage and frequency fluctuate widely, such as a
generator.
●
If the generator's output voltage/frequency falls out of the input voltage/frequency range, the unit will enter
Battery Mode.
●
Even if the input frequency is within the range, the unit will enter Battery Mode when a rapid change (5
Hz/sec or greater) occurs.
In the event you transfer or sell this unit to a third party, please include all of the
documentation that came with the unit. This is to ensure that the unit is used in
line with the conditions described in the included documentation.
●
This manual contains important safety-related information. Please read and understand the contents of
the manual before beginning operation.
This unit uses lead acid batteries,
●
Which are a valuable recyclable resource. Please recycle.
Take measures for handling unforeseen accidents, such as data backup and
system redundancy.
●
The output may stop when there is a circuit failure in the UPS.
Usual operation
●
You may either leave the power switch of the unit ON (operation status) or turn it OFF each time when
stopping the connected system. Choose whichever operation method is more convenient. We recommend
turning OFF the power switch when you do not use connected devices for a long time.
●
The battery can be charged once the unit is connected to a commercial power source.
Quitting Battery Mode
If a power failure lasts for an extended period of time, the battery discharges completely and power output
●
from the unit stops. Shut down your computer after performing appropriate procedures (for example, sav-
ing data) while the unit is still supplying power.
Rebooting
●
If the battery discharges completely during a power failure, the output stops. After recovery from the
power failure, the unit automatically restarts and output begins. If you do not want to restart the connected
devices, disable the "Settings" - "Boot Settings" - "Auto reboot" setting in the menu on the unit's LCD, or
turn OFF the power switch of the connected devices.
Scheduled operation using the UPS monitoring software
●
When performing scheduled operation in which the UPS is stopped and a device such as a breaker is
used to stop the UPS at the same time that commercial power stops, specify a period of no more than 3
months for the start of the next operation.
If you specify a period longer than 3 months, the internal timer is reset and the scheduled operation does
not start. Note that this period reduces to approximately half when the battery needs to be replaced. If a
period of 3 months is exceeded, you start operation by supplying commercial power and pressing the start
switch. However, if the battery needs to be replaced, you may not be able to start operation.
In this case, replace the battery.
