Inspecting the Battery (Battery Check)
Inspection of the battery is performed using a battery check function. There are two kinds
of battery check functions, an automatic check and a manual check.
The manual check is not necessary ordinarily since automatic check is performed while
the UPS is operating.
Automatic check is performed in the following cases:
When the operation of UPS is started up
Every two weeks in an operation continuation state
When the UPS has switched to the normal operation from the bypass operation
Perform manual check in the following cases:
When a warning beep sounds due to the abnormalities in a battery
When performing the battery check other than the automatic check
Important
Do not perform the battery check in succession.
When the battery check is performed, the UPS temporarily switches to the battery
operation.
If the battery check is performed in succession, there is fear of the battery deterioration
or a shortening of a cycle of battery replacement since the battery becomes an
over-discharge state.
Confirming the state of the UPS
1.
Confirm that the UPS is operating normally.
