■ Actions during operation
There is no problem if the “Power” switch of the UPS remains on (operating status), or if it
is turned off every time the connected systems are stopped. Operation can be performed in
whichever way.
It is recommended to turn off the power switches of the connected devices which are not
used for a long time.
The battery can be charged by connecting the “AC input” plug of the UPS to the
commercial power.
■ Actions when power outage has occurred
When a power outage or an input power fault occurs, operation is automatically switched to
back up operation, and power output continues using electrical power from the battery (this
is referred to as “backup operation”).
During backup operation, the screen becomes the battery mode as follows.
