When you
fi
nish connecting the unit, con
fi
rm that the backup operation works properly.
Check that the Battery Mode is performed normally according to the following procedure.
(In this operation check, the effects of a power failure are reproduced by disconnecting the AC input
plug from the wall outlet (commercial power) or, when using the BU200RW/BU300RW, by turning OFF
the INPUT PROTECTION switch (input overcurrent protection switch).)
(1) Turn ON the unit's power switch.
The beeper sounds and the current settings are displayed on the LED.
After 5 secounds, the self-diagnostic test is performed in Battery Mode for approximately 10
seconds.
When the self-diagnosis test
fi
nishes normally, the unit’s operation switches to commercial power
and the status indication below is displayed.
(When the battery voltage is low, the self-diagnostic test is not performed and output begins
immediately via commercial power.)
(2) Bring all the connected devices into operation.
(Including devices connected to the AC outlet of your PC.)
The unit was charged before shipment, but it may have
self-discharged during shipment, resulting in a reduced
backup time. We recommend charging the unit before use.
.
(3) Under this condition, check the the unit's LED display and beep sound.
Are they in the same status as shown below?
