2. Installation and connection
The beeping sound varies depending on the state of the battery.
The operation is normal.
Proceed to (5).

Yes
No
The operation is abnormal.
•
If the display looks like either of those shown in "C. Failure (displays and beeps when a
failure occurs in a device) of "3-3 Beeps and displays” on page 33, take the measures
necessary for troubleshooting and then go back to (4).
•
In a case where there is no backup and both the UPS and devices linked to the UPS stop, a
weak battery charge may be the cause.
Insert the AC Input Plug of the UPS into a wall outlet (commercial power), charge the battery
for at least 12 hours, and then go back to (4).
♦
If the problem still remains after performing the two checks above, contact our Customer Support Center.
(5) Insert the AC Input Plug into a wall outlet (commercial
power) again.
The Battery Mode Lamp ( ) goes out, the AC Input
Lamp goes on, and the beeping stops.
(It should appear as in the figure on the right.)
The operating checks are complete.
2-7 Charging the battery
When you connect the AC Input Plug of the UPS to a wall outlet (commercial power), battery-charging will
begin automatically, and it will be fully charged within 12 hours. (When no MB240XR add-on battery is connected.)
(The batteries will charge regardless of whether the UPS is being used or not, and regardless of whether the
power switch ( ) is ON or OFF.)
●
The UPS has been charged prior to shipment, but the backup time may be shorter when using the UPS for
the first time due to natural discharge.
We recommend charging the UPS before use.
2-8 Measuring the backup time
After "2-6 Checking the operation" is complete, you can start the actual operation. However, we recommend
measuring the actual backup time of the UPS in your operating evironment before starting the initial operation.
That gives you a guideline for the battery check.
See also "4-1 Measuring method of the backup time" on page 36.
