The AC normal (Green) LED will be on when the UPS is 
operating in the normal AC mode and will turn off when the 
UPS is operating in the Battery mode. 

The On-Battery (Yellow) LED will turn on when the UPS is 
operating in the Battery mode and will turn off when the UPS is 
operating in the AC normal mode. 

The Warning / Fault (Red) LED will turn on when the UPS 
detects an internal fault, an Overload, a Weak / Bad / 
Disconnected Battery, a Low Battery Warning, or a Site Wiring 
Fault.  The LED will be off when the UPS is operating 

normally. 

 
See the LED and Alarm functions table for more information. 
 

The On/Off Button functions as follows: 
When the UPS is in the Off position, press and hold the On/Off 
button until the alarm sounds one beep and then release to turn 
the UPS On. 
 
When the UPS is in the On position, press and hold the On/Off 
button until the alarm sounds one beep and then release to turn 
the UPS Off. 

When the unit is operating in Battery mode, pressing the Alarm 

Silencer Button will silence the audible alarm.    Once the UPS 
reaches the LBW (Low Battery Warning) threshold the alarm 
will start beeping.  The alarm cannot be silenced during the 
LBW alarm.  Once the UPS transfers back to the AC normal 

mode the alarm will reset back to the default setting. 

 
Except for the On-Battery alarm all the other Warning/Fault alarms cannot 
be silenced.  Once the Warning/Fault condition has been corrected the 
alarm will reset to default.
