7. Using the UPS monitoring software and contact signal
47
Explanation
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 is dead.
If a period of 3 months is exceeded, you start operation by supplying commercial power and pressing
the Start Switch. However
, if the battery is dead, you may not be able to start operation. In this case,
replace the battery according to "6-2 Replacing the battery" on page 37.
Start of operation in scheduled operation using the UPS monitoring software
●
T
o manually start up this unit after it has been stopped by a scheduled operation, turn OFF the power
switch and turn it back ON again.
T
o stop the unit when it is in operation, turn OFF the power switch.
Auto restart after OS closing processing using the UPS monitoring software
●
When
a power failure occurs, certain PCs (*1) automatically restart immediately after the OS is shut
down by auto shutdown.
In
this
case,
the
UPS
stops
during
or
after
the
restart
of
the
PC,
which
may
damage
les
and
the
hard
disk.
You can avoid this phenomenon by disabling POWER MANAGEMENT in the BIOS settings of the
PC.
*1) Certain PC: It is known that this phenomenon occurs for MICRON's Millennia Mme.
Precautions when “setting the UPS to stop automatically” after OS shutdown
●
If,
after a power failure occurs, the power is restored while auto shutdown processing is being per-
formed, UPS output stops once after the set time elapses. After shutdown processing is complete, do
notturnONthecomputeruntiltheUPShasnishedrestarting.
