5.3 Inspecting the Battery
There are two types of battery check functions: automatic checks
and manual checks. Automatic checks are performed while the UPS
is running, so manual checks are not usually required.
Automatic checks are performed in the following cases:
At the start of UPS operation
Every two weeks in continuous operation
When switching from bypass operation to normal operation
Manual checks are performed in the following cases:
When a warning beep sounds due to a battery malfunction
When performing a battery check other than the automatic check
IMPORTANT
Do not perform the battery checks continuously.
When performing battery checks, the internal battery actually gets
discharged to check the voltage.
Consecutive battery checks may degrade the battery and shorten the
battery replacement cycle.
Checking UPS status
1. Check if the UPS is operating properly.
When all the LEDs on the front of the UPS are off, turn on the UPS and
proceed to step 2. For details, refer to Chapter 4.1 “Turning on the UPS”.
Also refer to Chapter 6 "Troubleshooting”.
RUN LED (green) is lit.
