If an overload occurs, the OVERLOAD LED will light and an uninterrupted alarm will be
heard. Under this condition, check the load connected to the UPS.
OVERLOAD
BUCK/BOOST
If the UPS detects a high utility voltage, the function of the buck is to automatically reduce the
output voltage to its nominal level. If the UPS should detect a low utility voltage, the boost
function will raise the output voltage to its nominal level. These two functions are repre-
sented by their respective LED on the front panel.
BATTERY REPLACE
This function is to alert users of the need to replace the batteries. When the microproces-
sor in the UPS detects a battery fault, the UPS alarm will give out three beeps. Each beep
lasts for 0.5 seconds and interrupted by an interval of 0.5 seconds. After the initial 3
beeps, the alarm will continue to sound every hour.
