6. Maintenance
6.1 Verifying UPS operation
It’s
necessary to provide the following operations during the maintenance:
1. Check the operation of the UPS.
If the mains voltage is in allowable range, the UPS is working in utility
mode. If the mains voltage is out of the allowable range, the UPS operates
in battery mode. In both cases, this is not a fault.
2. Check the transition from one mode to another.
Disconnect power to simulate network failure. The UPS transfers into the
battery mode, then try to reconnect the power cable and make sure that the
system returns to the utility mode.
3. Check for errors
During the tests, described above, make sure that the operating mode on
the display is the same as the actual operating mode of the UPS.
6.2 UPS maintenance
