4 Checking the battery
4-1 Checking the battery
■
Manual testing
This test can also be performed manually. Press and hold
the “Buzzer Pause/Test” switch of the UPS for 5 seconds or
longer. When the beeper begins to sound intermittently,
release the Switch.
By performing the self-diagnosis test, backup operation is started automatically.
(Status indicator “
”, No beep sounds.)
After the test is completed, UPS automatically returns to the normal operation.
If the status indicator/battery replacement lamp blinks and the beeper sounds: See also
"3-4 Interpreting beeps and displays".
Additional Information
●
Follow the directions for the solutions described in “3-4-4 Displays and beeps when
there is an equipment failure” and “4-2 Replacing the battery”.
●
The self-diagnosis test can be performed also from attached UPS monitoring software.
For more details, refer to the online help of UPS monitoring software.
4-1-3 Estimated backup time
The backup time varies depending on the capacity of connected devices.
After calculating the total capacity of connected devices, refer to the graph of the backup
time to obtain an estimation of the initial value of the backup time. (This is also applied to
checking the battery.)
1.
Convert the total capacity (power consumption) of the connected devices to watts (W).
For the indication of connected devices, check your computer and the rear of the
display. The indicator can show values in three different ways: volt-amperes (VA),
amperes (A), and watts (W).
Example 1) 100 VAC, 50/60 Hz, 145 W
Indication
Value
Example 2) 100 VAC, 50/60 Hz, 1.8 A
A
A × power factor × 100 = W
Example 3) 100 VAC, 50/60 Hz, 150 VA
VA
VA × power factor × 100 = W
For devices that use the VA or A indication, convert the capacity into W. Multiply the
value indicated on devices by the value in the right table for conversion.
(When the power factor is unknown, enter “1”. The power factor usually ranges
between 0.6 and 1.)
2.
Add the values converted into W to obtain the total capacity of the connected devices.
3.
Calculate the initial value of the backup time for the total capacity of the connected
devices from the graph below.
・
Graph of backup time (graph of initial values for products that have not been used
at 25°C). The backup time becomes shorter than the graph (table) below when
temperature is lower.
・
The smaller the capacity of connected devices becomes, the longer the backup
time becomes.
