4.3 When Utility Power Is Interrupted
In case the utility power is interrupted, the UPS converts the built-in battery source to output terminals
immediately to protect your critical loads from loss of data or damage.
Battery back-up time is more than 10 minutes for full load and can be extended by removing non-critical
loads.
After an utility power blackout, the audible alarm and "
LINE FAILURE " indicator on LCD panel will start
operating.1 minute after the power is interrupted, and you will see the message " BAT.USED :001min "on
the LCD panel. This will show you for how long the batteries were used since the power was interrupted.
When the "
Battery Low " alarm appears, you have to shut down all your loads immediately, and turn the
main switch PK1 to position " 0 ".
