When the UPS is overloaded, the alarm will beep twice every second. Some unnecessary loads
should be removed from the ups one by one to decrease the loads connected until it reaches a value
less than 90% of its nominal power capacity.
While doing a battery test, the symbol for battery test will be shown on the display.
If the battery status is “bad battery detected” or “battery disconnected”, the symbol for battery
failure will be shown and UPS will alarm.
